How to enable "Detected multiple build versions with a GUID" when converting a project from VS 2008 to VS 2010

Question

I just converted my project from VS 2008 to VS 2010, here is the error I am getting now: -

Multiple build versions with a GUID detected. '' Try to pre-import one of these assemblies.

I already tried to clear decisions, projects and recompile, close and open again. but no luck.

Answer 1

Are your links to the debug folder? If you want to delete them.

EDIT - since you mentioned a COM object in your comment ....

Application for assembling assembly errors - several build versions detected

Looks like a bug in VS 2010 ....

Answer 2

You should try to change .net Framework3.5 to .net Framework4.5.

Answer 3

If you open your Assembly.cs file, there will be a GUID for your application ... for smiles, I just try changing the GUID by creating a new new one (you do not have VS open menu action for generating a GUID, but it is there). Then try recompiling. your project and the final application.

Answer 4

There was the same problem. We noted some links that looked invalid in the Directories folder in Solution Explorer. Right-click and select Delete.

After removal, the thing worked just fine.
