Error trying to edit source code in Integration Studio

Error trying to edit source code in Integration Studio

  
Hi,
In Integration Studio, when I try to edit the source code, the Visual Studio opens, but I keep getting this error, failling then to edit the refered code. I'm sending the error message attached.
Does anyone know why this happens?
Best Regards

This is just a wild guess, can't it be that you trying to open a VS2005 project in VS2003 ?

I´m running the MS VS 2005 version so, it shouldn't be.
Nevertheless, thank's for the reply.
Hi Francisco,

My recomendation is to delete the folder that as been created when you have been compiled de extension, and recompile it again.
No, still doesn't work.
It happens with all extensions even the ones created correctly by the community.
Thank's
I was lacking the C# compiler.
Installed the pro version of Visual Studio, and works fine now!

Thank's for your help.
