I got an email from someone the other time asking me how i fixed the error above.The error comes up when you want to create a new C# project. VS.NET pops up the message and says library not registered" .I have also blogged the first error i got in this blog related to Visual Studio.Net.
Actaully who would have ever thought a DLL from the Visual C++ directory tree in Visual Studio would get unregistered simply by running a VS add-in deployment package install/uninstall a few times... and then would keep C# project wizards from working??
But after some googling i came across
the fix which i guess has saved many people from reinstalling VS.Net:)
So it came out that the fix is very simple by(registering the dll):-
regsvr32 "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\vcpackages\csproj.dll"
And you can find the cSproj.dll in the VC7 folder.
My advice is if you have similar problem try looking for a fix before re-installing.
Happy programming.
