Unable to change target framework version to 3.5 because Visual Studio "thinks" it is a test project

I do not consider this a viable solution as removing this GUID renders the project useless because after doing so you can no longer run the tests.

Attempting to put the ProjectTypeGuid back in the .csproj file after changing the Target Framework from 4.0 to 3.5 results in the Conversion wizard being invoked which in turn attempts to change the Target Framework back to 4.0!!!

Please advise if there will be a fix for this or not.

Izzy, thanks for the solution. That is exactly what I needed to know. We are going to upgrade our projects this week and this will certainly simplify the process for us.

Hi -

Thanks for reporting this. The way that Visual Studio determines the type of a project is by examining the <ProjectTypeGuids> XML element in the .csproj or .vbproj file. In your case, you have the following:

<ProjectTypeGuids>
{3AC096D0-A1C2-E12C-1390-A8335801FDAB};
{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}
</ProjectTypeGuids>

(line breaks added for clarity). The {3AC096D0-...} GUID represents the Test Project type. If you remove that GUID (and the separator semicolon), you should be left with a plain-vanilla C# project that you'll be able to re-target.

Thanks,
-- Izzy
