framework .net 2.0 not working with VS 2010.

I am a software engineer and I will surely assist you. You have upgraded your 2005 .Net to 2010 .Net and you have not upgraded your frame work 2.0. You have surely missed a trick here. The 2010 .Net supports the 3.0 and above frame work. You can use the 3.5 or the 4.0 frame work in your .Net to work it again. Now what can you do to remove this problem completely? First of all you have to download or buy the frame work 3.0 or above in your computer. Install that software in your computer. Check if it works. If still not working than try to uninstall the 2010 .Net and first of all install the 3.0 or above frame work and after that reinstall the .Net 2010 again. Check if it works. Hope by the end of this all your .net 2010 software will resume its work. It was really nice to help you on this.
