Another Microsoft .NET Framework query

I have just bought a new Dell Inspiron 580 pc which is running Windows 7.  The following error message appears shortly after startup. Apparently Microsoft.NET Framework is pre-installed on my computer. How do I get rid of this message please, and why would I want .NET Framework anyway?

I would be grateful for any help. Thank you.

To enable just-in-time (JIT) debugging, the .config file for this

jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
