could not find TemporaryGeneratedFile_GUID

Question

I copied and pasted a visual studio solution from a folder to another, and now when I open the new one I see in the output window (show output is set to intelliSense):

How can I make this messages go away?

Answer 1

open your projectname.csproj file in any text editor such as notepad++. Find code similar as follow:

<Compile Include="obj\Debug\TemporaryGeneratedFile_036C0B5B-1481-4323-8D20-8F5ADCB23D92.cs" />
<Compile Include="obj\Debug\TemporaryGeneratedFile_5937a670-0e60-4077-877b-f7221da3dda1.cs" />
<Compile Include="obj\Debug\TemporaryGeneratedFile_E7A71F73-0F8D-4B9B-B56E-8E70B10BC5D3.cs" />
<Compile Include="obj\Release\TemporaryGeneratedFile_036C0B5B-1481-4323-8D20-8F5ADCB23D92.cs" />
<Compile Include="obj\Release\TemporaryGeneratedFile_5937a670-0e60-4077-877b-f7221da3dda1.cs" />
<Compile Include="obj\Release\TemporaryGeneratedFile_E7A71F73-0F8D-4B9B-B56E-8E70B10BC5D3.cs" />

Remove those lines and restart visual studio or unload your solution and reload the solution.

Answer 2

Try deleting the suo file. That seems to help my case sometimes.
