Error MSB4186 Invalid static method invocation syntax: "[System.IO.Path]::GetDirectoryName()". Method 'System.IO.Path.GetDirectoryName' not found. Static method invocation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(a, b)). Check that all parameters are defined, are of the correct type, and are specified in the right order. ScaleUnit C:\Users\Administrator.nuget\packages\microsoft.dynamics.commerce.sdk.scaleunit\9.45.23276.2\build\Microsoft.Dynamics.Commerce.Sdk.ScaleUnit.targets 197

Ongoing investigation on why the MSBuild fails on Microsoft.Dynamics.Commerce.Sdk.ScaleUnit.targets 197

In case anyone else has seen this issue and are still looking for a solution.

Any idea when Microsoft will fix this?
I am still getting this error and we are now on v10.0.38.
We were on v10.0.35 when I reported this error to Microsoft.
