I just converted a solution from VS 2008 to 2010, almost all of the projects were successfully converted. However, one of the project (say Project X) conversion was kind of unsuccessful with message (This project needs not to be converted.)
But now i am not able to build solution, because the projects having references to Project X are not able to access members defined there in. The error messages are,
- The type or namespace name 'ABC' could not be found (are you missing a using directive or an assembly reference?)
While there is a warning message too,
- The primary reference "F:\Project X.dll" could not be resolved because it has an indirect dependency on the .NET Framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework.
I have checked Solution Explorer -> Properties -> Application Tab for both referring and referred projects, both target Framework 3.5.
The Project X is getting built easily itself.
