Answer 1

After facing so many troubles, here is the solution that I found.

1. open your project folder.
2. find Your_Project_Name.csproj[Visual C# Project file (.csproj)]

3. open that file in any text editor and find your missing file ItemGroup.

4. remove that ItemGroup and open once again your project and build

5. If that reference is important for you then add once again.
