When I run my code from Visual Studio 2015 it gives error and the build failed.
When I build or rebuild or clean the solution there is no error, But when I run it by clicking on the Start button it failed. It is a desktop application.
I cannot see any error in the error list.
When I changed the Error log file verbosity from Minimal to Detailed, I can see following failure error in the output window.
2>Output file "obj\Debug\RdlCompile.compiled" does not exist.

Had the same issue in VS 2017. Uninstall and reinstall of VS 2017 fixed the issue for me.
