This plugin offers up two compilers to vim: dotnet build and dotnet test and their respective errorformat.

Whenever a .cs file is opened, the compiler is set to dotnet_build, so whenever :make is run it will spawn a dotnet build command. The plugin is nice to use with vim-dispatch's :Make command which will compile (dotnet build) and show any errors in the quickfix window.

There are two options to change what messages are populated into the quickfix windows.

let g:dotnet_compiler_errors_only = 1
let g:dotnet_compiler_warnings_only = 1

These correspond to --consoleLoggerParameters:ErrorOnly and --consoleLoggerParameters:WarningsOnly.

vim-compiler-plugin-for-dotnet automatically sets b:dispatch = 'dotnet test' for .cs files. This makes vim-dispatch's :Dispatch command run dotnet test (compile, then run the entire test suite) and also show any build or test errors in the quickfix window.

Quickfix entries for test failures do not report anything but the file, line number and name of the test that failed. This is done to keep the errorformat simple and compatible with all the dotnet core test project types (xunit, nunit, or mstest).

To see explanations of what went wrong in a specific test, the vim-test plugin is nice. Put this in your vimrc:

let g:test#csharp#runner='dotnettest'
let test#strategy = "vimterminal"

Now place the cursor in the failing test and run :TestNearest and the details will be in a new split.

If you use vim-plug add this to your plugins:
