Visual Studio MacOS error MSB4057: The target "Build" does not exist in the project

Question

I have created a simple C# .net core console application project in VS MacOS. But I get error MSB4057. There a similar question on stackoverflow but doesn't explain anything how to fix this kind of error.

The problem is same when I create asp.net core project.

Build FAILED.

Answer 1

It is very important to upgrade Mono 4.8 to its latest build, (in my case)

http://www.mono-project.com

Then the bundled build environment can successfully compile the project.

It seems the built in updater does not upgrade Mono runtime as expected.

Updated: Now the installer should assist you install Mono 5.0 automatically.
