✅ Get full paths to executables in %PATH%

Is there an easy way to get the full path of a program that's available in the shell because of the PATH environment variable (like

gcm

gcm

does in powershell or

which

which

on unix)?

e.g.

ResolvePath("dotnet")

ResolvePath("dotnet")

would return

C:\Program Files\dotnet\dotnet.exe

C:\Program Files\dotnet\dotnet.exe

I don't want to start a process and I don't want to iterate over PATH myself.
