Any idea what file I should look at in my solution?

Answer 1

This error is caused by corrupted proj file.

Visual Studio always has backup project file at specific folder.

Please browse to:

C:\Users\\Documents\Visual Studio \Backup Files\

You should see 2 files like this:

Original-May-18-2018-1209PM..csproj
Recovered-May-18-2018-1209PM..csproj

You only need copy file:

Original-May-18-2018-1209PM..csproj

And re-name as

.csproj 

and override at root project folder.

Problem is solved!
