Dear All,
I had ASP 2.0 installed on my machine, recently I have installed Asp 3.0 framework only. Now my all old applications are throwing compile time error.
How to revert back to old framework. Is there any command which will set the current version.
Error 1 Could not load file or assembly 'System.Runtime.Serialization, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

Please suggest.

Regards,
PPCC
