Resources are .resx files with string values that we use for error messages and such.
They live in src\<project>\resources folders.
At the moment dotnet cli doesn't support generating C# bindings (strongly typed resource files).
We are using our own Start-ResGen to generate them.
Usually it's called as part of the regular build with
PS C:\> Start-PSBuild -ResGen
If you see compilation errors related to resources, try to call Start-ResGen explicitly.
PS C:\> Start-ResGen
Don't edit .resx files from Visual Studio.
It will try to create .cs files for you and you will get whole bunch of hard-to-understand errors.
To edit a resource file, use any plain text editor. A resource file is a simple XML file, and it's easy to edit.
dotnet cli doesn't support embedding old-fashioned .txt resource.
You can do a one-time conversion of .txt resources into .resx files with a helper function:
# example, converting all .txt resources under src\Microsoft.WSMan.Management\resources
PS C:\> Convert-TxtResourceToXml -Path src\Microsoft.WSMan.Management\resources
.resx files would be placed next to .txt files.
