.NET Quick-Ref

• run xunit tests with output to console: dotnet test --logger "console;verbosity=detailed" --filter <filterexpr>

  • <filterexpr> can be e.g. the test name, or with XUnit.Categories e.g. Feature=83922. But if we are interested in the output then it's best to run one test at a time, otherwise it's hard to find.

• run fsharp fsx script dotnet fsi <filename>

• open fsharp interpreter dotnet fsi --readline
