A helper tool to prejit everything in the current folder in just one command.
cd folder/with/managed/libs dotnet prejitall # or if you want to use a custom crossgen2.exe: dotnet prejitall C:\prj\runtime-main\artifacts\bin\coreclr\windows.x64.Checked\crossgen2\crossgen2.exe
NOTE: target directory is expected to have all possible dependencies (e.g. result of dotnet publish command).
dotnet tool install -g prejitall
