Just in Time (JIT) and its types

Nov 18, 2010 Posted by Lara Kannan 0 comments

Just in Time (JIT)

JIT is responsible for converting the managed code into machine code. It is a part of the runtime execution environment.

JIT known as dynamic translation is a technique for improving the runtime performance of a computer program.


JIT builds upon two earlier ideas in run-time environments:

  • Byte code compilation
  • Dynamic compilation.

It converts code at runtime prior to executing it natively, for example byte code into native machine code.

The performance improvement over interpreters originates from caching the results of translating blocks of code, and not simply reevaluating each line or operand each time it is met.

It also has advantages over statically compiling the code at development time, as it can recompile the code if this is found to be advantageous, and may be able to enforce security guarantees.

Thus JIT can combine some of the advantages of interpretation and static compilation.

Several modern runtime environments, such as Microsoft's .NET Framework and most implementations of Java and most recently Action script 3, rely on JIT compilation for high-speed code execution

JIT are of three types :

  1. Pre JIT
  2. Econo JIT
  3. Normal JIT

1. Pre JIT : Compiles entire code into native code at one stretch

  1. It converts all the code in executable code
  2. it is slow
  3. It compiles complete source code into native code in a single compilation cycle.
  4. This is done at the time of deployment of the application.

2. Econo JIT : Compiles code part by part freeing when required

  1. It will convert the called executable code only.
  2. it will convert code every time when a code is called again.
  3. It compiles only those methods that are called at runtime.
  4. these compiled methods are removed when they are not required.
  5. This compiler converts the MSIL code into native code without any optimizations

3. Normal JIT Compiles only that part of code when called and places in cache

  1. It will only convert the called code
  2. It will store in cache so that it will not require converting code again.
  3. Normal JIT is fast.
  4. Compiles only those methods that are called at runtime.
  5. These methods are compiled the first time they are called, and then they are stored in cache.
  6. When the same methods are called again, the compiled code from cache is used for execution.

Types of Services in WCF

Posted by Lara Kannan 2 comments

There are three types of services in WCF, and they are the following:
  • Typed
  • Untyped
  • Typed message
Typed Service

A typed service is the simplest of services, and is very similar to the methods in a class, in that both the parameters and method return values can be both simple or complex data types.

A typed service can also return a value or return a modified parameter value. The following example illustrates a typed service in which typed operations are used:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(string title, decimal cost);

}

This next example shows the use of the ref parameter to return a modified parameter value:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(string title, decimal cost, ref ordernumber);

}

Data contracts provide the ability to extend this functionality and accept complex data types as parameters or returned results.

Typed Message Service

A typed message service accepts and returns message information via custom classes that are defined by message contracts. With a typed message service the operation accepts a custom message parameter in the form of a message class, and the responsibility of deciphering the message falls upon the service operation.

The following example shows a service contract along with a defined typed message that is used as a parameter in a typed service operation:

[ServiceContract]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(Contract MyContract);

}

[MessageContract]
public class MyContract
{

[MessageHeader]
string Title;

[MessageBodyMember]
decimal cost;

}

Untyped Service

Untyped services let you do your work at message level, so this is the most complex of the service types. At this level the service operation accepts and returns message objects so it is recommended that you use this type of service only when you need this level of control, that is, working directly with the message.

The following example shows an operation contract passing a message object as an untyped service operation:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IBookOrder
{

[OperationContract]
void PlaceOrder(message IncomingMessage);

}

WCF Service Bindings - Basic

Posted by Lara Kannan 0 comments
Windows Communication Foundation Bindings

This article offers a brief explanation on the basic concepts of the Communication part in the Windows Communication Foundation - WCF. In order to communicate with a WCF service, the client needs to know simple details like 'ABC' of the service.

Whats meant by ABC of WCF ?
Before we learn the ABC of WCF, we need to know how a WCF service is made accessible to the clients.

A WCF service allows communication through an Endpoint. And the endpoint is the only point of communication of the WCF service that enables message exchange with the client as shown in below figure.


And this Endpoint needs to set the ABC attributes of the WCF service as shown in the below figure.


Thus in the WCF world, ABC is an abbreviation of Address, Binding and Contract attributes of an Endpoint.

An example of the Endpoint

Let us quickly run through an example of an endpoint setting in the web.config file at the service side.
<endpoint 
address="http://localhost:8731/EmpWCFService.ServiceImpl.Manager/"
binding="basicHttpBinding"
contract="EmpWCFService.ServiceContract.IEmployee" />

Where,
- address is the network address of the service,
- binding specifies transport protocol (HTTP, TCP, etc.) selected for the service &
- contract is the interface the service implements.

So, what is the Binding?

The Binding is an attribute of an endpoint and it lets you configure transport protocol, encoding and security requirements as shown in the below figure.



Types of Binding

WCF supports nine types of bindings. WCF allows you to transmit messages using different transport protocols (such as HTTP, TCP, and MSMQ) and using different XML representations (such as text, binary, or MTOM).

  1. Basic binding - BasicHttpBinding
    • It is suitable for communicating with ASP.NET Web services (ASMX)-based services that comfort with WS-Basic Profile conformant Web services.
    • This binding uses HTTP as the transport and text/XML as the default message encoding.
    • Security is disabled by default
    • This binding does not support WS-* functionalities like WS- Addressing, WS-Security, WS-ReliableMessaging
    • It is fairly weak on interoperability.
  2. Web Service (WS) binding - WSHttpBinding
    • Defines a secure, reliable, interoperable binding suitable for non-duplex service contracts.
    • It offers lot more functionality in the area of interoperability.
    • It supports WS-* functionality and distributed transactions with reliable and secure sessions using SOAP security.
    • It uses HTTP and HTTPS transport for communication.
    • Reliable sessions are disabled by default.
  3. TCP binding - NetTcpBinding
    • This binding provides secure and reliable binding environment for .Net to .Net cross machine communication.
    • By default it creates communication stack using WS-ReliableMessaging protocol for reliability, TCP for message delivery and windows security for message and authentication at run time.
    • It uses TCP protocol and provides support for security, transaction and reliability.
  4. MSMQ binding - NetMsmqBinding
    • This binding provides secure and reliable queued communication for cross-machine environment.
    • Queuing is provided by using MSMQ as transport.
    • It enables for disconnected operations, failure isolation and load leveling
  5. Peer network binding - NetPeerTcpBinding
    • This binding provides secure binding for peer-to-peer environment and network applications.
    • It uses TCP protocol for communication
    • It provides full support for SOAP security, transaction and reliability.
  6. Duplex WS binding - WSDualHttpBinding
    • This binding is same as that of WSHttpBinding, except it supports duplex service.
    • Duplex service is a service which uses duplex message pattern, which allows service to communicate with client via callback.
    • In WSDualHttpBinding reliable sessions are enabled by default. It also supports communication via SOAP intermediaries.
  7. IPC binding
    • Offered by the NetNamedPipeBinding class, this uses named pipes as a transport for same-machine communication. It is the most secure binding since it cannot accept calls from outside the machine and it supports a variety of features similar to the TCP binding.
  8. Federated WS binding
    • Offered by the WSFederationHttpBinding class, this is a specialization of the WS binding, offering support for federated security.
  9. MSMQ integration binding
    • Offered by the MsmqIntegrationBinding class, this converts WCF messages to and from MSMQ messages, and is designed to interoperate with legacy MSMQ clients.
That's all at this moment. Will see more in the next post.

Utilize a simple extension method to capitalize the first letter of a string.


public class Program
{
static void Main(string[] args)
{
string s = "toUpperFirstLetter";

// ToUpperFirstLetter is the extension method defined below
Console.WriteLine(s.ToUpperFirstLetter());

// output: ToUpperFirstLetter
Console.ReadLine();
}
}

// string extension class
public static class StringExtension
{
// string extension method ToUpperFirstLetter
public static string ToUpperFirstLetter(this string source)
{
if (string.IsNullOrEmpty(source))
return string.Empty;
// convert to char array of the string
char[] letters = source.ToCharArray();

// upper case the first char
letters[0] = char.ToUpper(letters[0]);

// return the array made of the new char array
return new string(letters);
}

Difference between BasicHttpBinding and WsHttpBinding

Posted by Lara Kannan 0 comments
Difference between BasicHttpBinding and WsHttpBinding

If we want to summarize in one sentence, the difference between WsHttpBinding and BasicHttpBinding is that WsHttpBinding supports WS-* specification. WS-* specifications are nothing but standards to extend web service capabilities.

Below is a detailed comparison table between both the entities from security, compatibility, reliability and SOAP version perspective.



























































Criteria BasicHttpBinding WsHttpBinding
Security support This supports the old ASMX style, i.e. WS-BasicProfile 1.1. This exposes web services using WS-* specifications.
Compatibility This is aimed for clients who do not have .NET 3.0 installed and it supports wider ranges of clients. Many of the clients like Windows 2000 still do not run .NET 3.0. So older version of .NET can consume this service. As its built using WS-* specifications, it does not support wider ranges of client and it cannot be consumed by older .NET version less than 3 version.
Soap version SOAP 1.1SOAP 1.2 and WS-Addressing specification.
Reliable messaging Not supported. In other words, if a client fires two or three calls you really do not know if they will return back in the same order. Supported as it supports WS-* specifications.
Default security options By default, there is no security provided for messages when the client calls happen. In other words, data is sent as plain text. As WsHttBinding supports WS-*, it has WS-Security enabled by default. So the data is not sent in plain text.
Security options

  • None


  • Windows – default authentication


  • Basic


  • Certificate




  • None


  • Transport


  • Message


  • Transport with message credentials





One of the biggest differences you must have noticed is the security aspect. By default, BasicHttpBinding sends data in plain text while WsHttpBinding sends it in encrypted and secured manner.


To demonstrate the same, lets make two services, one using BasicHttpBinding and the other using WsHttpBinding and then lets see the security aspect in a more detailed manner.

WCF Data Services vs WCF RIA Services

Posted by Lara Kannan 0 comments
To sum up my findings as to the differences between WCF Data Services vs WCF RIA Services.































































WCF (ADO.NET) Data ServicesWCF (.NET) RIA Services
Expose data model as RESTful web servicePrescriptive approach to n-tier app development
Cross platform interoperation as a goal
- “Unlock data silos”
- Out-of-box support from future MS products such as SQL2008 R2, Azure, Excel 2010, SharePoint 2010
Designed specifically for end-to-end Silverlight & ASP.NET solutions
- Some technology proprietary to Silverlight (no WPF support)
- Use ASP.NET Authentication/Roles across SL and ASP.NET
- ASP.NET/AJAX can also access service layer
Loosely coupled clients and serversClient & server are designed and deployed together
Service layer exposes “raw” data sourcesOpportunity to easily add business logic into service layer
- Encourage “domain” concepts
- Strong validation framework
- Offline / Sync enabled
Service can be consumed from .NET, Silverlight, AJAX, PHP and Java (libraries available)Service can be consumed easily from SL, AJAX, WebForms
Service’s data source must:
- Expose at least one IQueryable property
- Implement IUpdateable if you desire updates
Service exposes domain objects via convention:
- IQueryable GetX
- UpdateX/InsertX/DeleteX
No design time experience yet (??)Design time experience with data sources, drag drop etc
- OData for all clients
- Within OData, multiple formats supported (JSON, XML etc)
- SOAP (binary) for SL clients
- JSON for AJAX clients
- SOAP (XML) for other clients
Discoverable (?)Non-discoverable
Hosted as WCF Service (.svc)Old version hosted in custom web handler (.axd).
New version is WCF service.
Standardized on OData protocol Will “support” OData
More mature – public for at least 2 years, formerly “Project Astoria”Less mature – public for 6 months

Common features


  • Based on WCF
  • Use a RESTful architecture
  • Can be used to expose any data source (sql, xml, poco/objects etc.)
  • Client side libraries provide ability to query using LINQ

General


  • Currently they do not share much (any?) technology / code
  • RIA Services is not based on top of Data Services
  • RIA Services & Data Services will “align”
  • OData eventually pushed down into WCF stack

"Publish failed" in Visual Studio 2008

Jul 15, 2010 Posted by Lara Kannan 0 comments

I was publishing a website today, and received an error message in the status bar indicating 'Publish failed. This was the only info I got, and couldn’t figure out what had happened as I had published successfully just minutes prior.

It turns out that there was an image that got included in my .csproj project file that had been deleted, and there was an error trying to locate it.

If you look in the output window (ctrl + alt + o) you will get a detailed list of any errors that occurred in the publishing process. I simply had to remove the image from the project file (as it didn’t exist any more anyway) and everything worked.

ASP.NET 3.5 vs ASP.NET 4.0

Jul 1, 2010 Posted by Lara Kannan 1 comments
Main Differences between ASP.NET 3.5 and ASP.NET 4.0.

ASP.NET 3.5 is having the following main features which are not availablle in the prior releases

  1. AJAX integration
  2. LINQ
  3. Automatic Properties
  4. Lambda expressions
I hope it would be useful for everyone to know about the differences about asp.net 3.5 and its next version asp.net 4.0 Because of space consumption I'll list only some of them here.

1. Client Data access:

ASP.NET 3.5: There is no direct method to access data from client side. We can go for any of these methods

  1. Pagemethods of script manager
  2. ICallbackEventHandler interface
  3. XMLHttphanlder component
ASP.NET 4.0: In this framework there is an inbuilt feature for this. Following are the methods to implement them.

  1. Client data controls
  2. Client templates
  3. Client data context
i.e we can access the data through client data view & data context objects from client side.

2) Setting Meta keyword and Meta description:

Meta keywords and description are really useful for getting listed in search engine.

ASP.NET 3.5: It has a feature to add meta as following tag
<meta name="keywords" content="These, are, my, keywords" /%>
<meta name="description" content="This is the description of my page" /%>

ASP.NET 4.0: Here we can add the keywords and description in Page directives itself as shown below.
< %@ Page Language="C#"  CodeFile="Default.aspx.cs" 
Inherits="_Default"
Keywords="Keyword1,Key2,Key3,etc"
Description="description" %>

3) Enableviewstage property for each control

ASP.NET 3.5: this property has two values "True" or "false"

ASP.NET 4.0: ViewStateMode property takes an enumeration that has three values: Enabled, Disabled, and Inherit. Here inherit is the default value for child controls of a control.

4) Setting Client IDs

Some times ClientID property creates head ach for the programmers.

ASP.NET 3.5: We have to use ClientID property to find out the id which is dynamically generated

ASP.NET 4.0: The new ClientIDMode property is introduced to minimize the issues of earlier versions of ASP.NET.

It has following values.

AutoID - Same as ASP.NET 3.5
Static - There won't be any separate clientid generated at run time
Predictable-These are used particularly in datacontrols. Format is like clientIDrowsuffix with the clientid vlaue
Inherit- This value specifies that a control's ID generation is the same as its parent.

'HttpUtility' is not a member of 'Web' in console application VS2010.

Jun 18, 2010 Posted by Lara Kannan 1 comments
Today I started my first console application developmentin VS 2010.

After I added the below code
System.Web.HttpUtility.UrlEncode(item)

and build the application, the system throws the error message like
Error message: 'HttpUtility' is not a member of 'Web'.

This error message suggests to add a reference to System.Web. When I look into it over the reference list, its was not there. I only have "System.Web.ApplicationServices" and "System.Web.Services". I dont know why its not there in the list?

Then my friend said, 'target framework may be different'. After that I checked the target framework, its was .NET Framework 4 Client Profile. Then I changed it as .NET Framework 4. Now my code works fine.

Hope this ll help you.

jQuery UI Date Picker control issue with .Net

Jun 10, 2010 Posted by Lara Kannan 0 comments
I build .net applications that require date entry, so I implement the Date Picker control often. Unfortunately, there is a problem when it is used on a field that is validated using a .Net validation control.

Upon clicking on a date, I get the following error:
length is null or not an object
This only occurs when using Internet Explorer. Currently, my only solution is to edit the source code.

Locate the following code in jquery-ui.js or ui.datepicker.js:
inst.input.trigger('change')

Replace it with:
if (!$.browser.msie){inst.input.trigger('change')}

This prevents the change event firing in IE.

New <%: %> Code Syntax in ASP.NET 4.0

Apr 7, 2010 Posted by Lara Kannan 1 comments
HTML Encoding

Cross-site script injection (XSS) and HTML encoding attacks are two of the most common security issues that plague web-sites and applications. They occur when hackers find a way to inject client-side script or HTML markup into web-pages that are then viewed by other visitors to a site.

This can be used to both vandalize a site, as well as enable hackers to run client-script code that steals cookie data and/or exploits a user’s identity on a site to do bad things.

One way to help mitigate against cross-site scripting attacks is to make sure that rendered output is HTML encoded within a page. This helps ensures that any content that might have been input/modified by an end-user cannot be output back onto a page containing tags like <script> or <img> elements.

How to HTML Encode Content Today

ASP.NET applications (especially those using ASP.NET MVC) often rely on using code-nugget expressions to render output. Developers today often use the Server.HtmlEncode() or HttpUtility.Encode() helper methods within these expressions to HTML encode the output before it is rendered. This can be done using code like below:

<div class="someclass">
<%= Server.HtmlEncode(Model.Content) %>
</div>

While this works fine, there are two downsides of it:

  • It is a little verbose
  • Developers often forget to call the Server.HtmlEncode method – and there is no easy way to verify its usage across an app

New Code Nugget Syntax

With ASP.NET 4 we are introducing a new code expression syntax () that renders output like blocks do – but which also automatically HTML encodes it before doing so.

This eliminates the need to explicitly HTML encode content like we did in the example above. Instead, you can just write the more concise code below to accomplish the exact same thing:

<div class="someclass">
<%: Model.Content %>
</div>

We chose the syntax so that it would be easy to quickly replace existing instances of code blocks. It also enables you to easily search your code-base for elements to find and verify any cases where you are not using HTML encoding within your application to ensure that you have the correct behavior.

Happy Coding!!!
