It happened with me today:

TL;DR; You might be using some C# code in your project who belong to a language version which is not supported by the .NET Framework version targeted by your project

Details:

I had two projects in my solution. One project was already existing. I added a new project targeting most recent .NET Framework v4.6.1 supported by Visual Studio(VS) 2017 class library project template. I used some C# language features which is present in C# v7.0. In such a case, VS can compile the project but can't create the output in bin directory.

Eventually I had to merge the new project code files into the existing old project which was targeting .NET Framework v4.5.1.

So I changed the target Framework version to the latest .NET Framework v4.6.1 for the existing projects also. Then the old project also started supporting my newly pasted C# language features.
