Yes, if you are debugging via Visual Studio.NET, just go to Immediate window.

Does SessionID change with every request in the asp.net 2.0 application?

  
Answer:
For any web programmer, its obvious to think and believe that SessionId remains same through out the user session and it was right till asp.net1.1. But in asp.net2.0, this behavior has changed. In the asp.net application new sessionid is returned with the response to every request until session objects are not used.

According to MSDN the reason/solution is:

"When using cookie-based session state, ASP.NET does not allocate storage for session data until the Session object is used. As a result, a new session ID is generated for each page request until the session object is accessed. If your application requires a static session ID for the entire session, you can either implement the Session_Start method in the application's Global.asax file and store data in the Session object to fix the session ID, or you can use code in another part of your application to explicitly store data in the Session object."

How to change the default page of a Silverlight application?

  
In a simple way we can set the default page, what we have to do is to change the default page of a silverlight application, we have to set the RootVisual property inside the Application_Startup event of the App.xaml file.


private void Application_Startup(object sender, StartupEventArgs e)
{
this.RootVisual = new MainPage();
}

What is Application Domain?

  
The primary purpose of the AppDomain is to isolate an application from other applications. Win32 processes provide isolation by having distinct memory address spaces. This is effective, but it is expensive and doesn't scale well. The .NET runtime enforces AppDomain isolation by keeping control over the use of memory - all memory in the AppDomain is managed by the .NET runtime, so the runtime can ensure that AppDomains do not access each other's memory.
Objects in different application domains communicate either by transporting copies of objects across application domain boundaries, or by using a proxy to exchange messages.
MarshalByRefObject is the base class for objects that communicate across application domain boundaries by exchanging messages using a proxy. Objects that do not inherit from MarshalByRefObject are implicitly marshal by value. When a remote application references a marshal by value object, a copy of the object is passed across application domain boundaries. (More...)

I have written an assembly that I want to use in more than one application. Where do I deploy it?

  
Assemblies that are to be used by multiple applications (for example, shared assemblies) are deployed to the global assembly cache. In the prerelease and Beta builds, use the /i option to the Alink SDK tool to install an assembly into the cache:
al /i:myDll.dll
A future version of the Windows Installer will be able to install assemblies into the global assembly cache. (More...)

What is an application domain?

  
An application domain (often AppDomain) is a virtual process that serves to isolate an application. All objects created within the same application scope (in other words, anywhere along the sequence of object activations beginning with the application entry point) are created within the same application domain. Multiple application domains can exist in a single operating system process, making them a lightweight means of application isolation.
An OS process provides isolation by having a distinct memory address space. While this is effective, it is also expensive, and does not scale to the numbers required for large web servers. The Common Language Runtime, on the other hand, enforces application isolation by managing the memory use of code running within the application domain. This ensures that it does not access memory outside the boundaries of the domain. It is important to note that only type-safe code can be managed in this way (the runtime cannot guarantee isolation when unsafe code is loaded in an application domain). (More...)

Describe the techniques for optimising your application?

  
. Avoid round-trips to server. Perform validation on client.
. Save viewstate only when necessary.
. Employ caching.
. Leave buffering on unless there is a dire need to disable it.
. Use connection pooling.
. Use stored procedures instead of in-line SQL or dynamic SQL. (More...)

Differences between application and session.

  
The session object maintains state on a per client basis whereas the application object is on a per application basis and is consistent across all client requests. (More...)

What is web application virtual directory?

  
A virtual directory appears to client browsers as though it were
contained in a Web server's root directory, even though it can physically Reside somewhere else. (More...)

what is different between session and application

  
session is a object that store information between http request for a paticular user.
->But application object are global for each user (More...)
