Hi Joseph,
After installing the extension with VS 2019 Professional with framework 4.6.1, I am getting an error related to finding the CrmServerLoginControl does not exist in XML namespace. Due to this the Plugin project does not get build successfully. I have tried this with the latest version from here.
That error indicates to me that assemby references within the projects are not resolving. This could be because dependent nuget packages have not been installed or there is some other build problem. Note that same error will display before the referenced nuget packages are installed due to assemblies in those nuget packages being referenced various projects
So I’d suggest ensuring that the nuget packages are installed or otherwise investigating if assembly references in any of the projects are not resolving correctly
You could also try this command to force nuget package reinstall: Update-Package -reinstall
