Yes, we can add two files with same name in GAC using versioning.

Difference between String and StringBuilder class?

the string class is immutable and therefore very inefficient if you need
to change it once it is constructed. For those cases, StringBuilder is
almost always a better choice. in case of string new object is create every time when we concate string.

Does ADO.NET supports automatic connection pooling?

Yes.

There is a pooling property with connection string. By default it is set to true.

Does CLR impose a strict versioning policy for the private assembly?

Answer is No. Private assembly are used by the application in which they are deployed. To use private assembly in any application, one needs to deploy them in the application's directory. Versioning needs to done for shared assembly which are stored in GAC and used by multiple applications.

How .NET Framework 2.0 tackles the unhandled exceptions?

For .NET Framework 2.0,There is a change in the behavior in which on any unhandled exception, .NET Framework 2.0 just ends the worker process. This exception cannot be caught as it is in the .Net framework 2.0, and when the .Net Framework "goes down", it also crashes the application. In .NET Framework 1.0 or 1.1, unhandled exceptions were ignored.

Workaround for this is :

Add this section in your app.config file.

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

   <runtime>

       <legacyUnhandledExceptionPolicy enabled="true" />

   </runtime>

</configuration>
