GitVersion: 4.0.1-beta1-58: dotnet build crashes with error MSB4044: The "GetAssemblyVersion" task was not given a value for the required parameter "NuGetVersion"

My project is multi-targeting net471 and netcoreapp2.1. The same error occurs when I build both targets and when I build either one individually.

There is a mismatch between SDK NuGet version (4.9.2) and the NuGet version the task factory was compiled against (4.9.0).
