Azure Pipeline build with GitVersion and .NET Core3 Preview fails

[thoemmi]

For the next version of my OSS project TinyLittleMvvm I switched to Azure Pipeline and use .NET Core 3 Preview (it's a WPF library). I'm using the most recent version 5.0.0-beta3-33 of GitVersion.
The Azure Pipeline is configured in azure-pipelines.yml.

Unfortunately, the build of ths library fails on the hosted build agent:

Exception in initialization: System.ArgumentNullException: Value cannot be null.

   at UtilPack.ArgumentValidator.ValidateNotEmpty(String parameterName, String value)
   at NuGetUtils.MSBuild.Exec.EnvironmentValue..ctor(EnvironmentInspectionResult result)

The task factory must return a value for the "TaskType" property. 

You can see the full build log here: https://dev.azure.com/thoemmi/TinyLittleMvvm/_build/results?buildId=63&view=logs&j=12f1170f-54f2-53f3-20dd-22fc7dff55f9&t=006e6f7c-8314-5e02-a3df-483f3a1f4cfa&l=48

It may be related to #1697, but in my case there's no deadlock.

Very similar issue for me with an ASP.NET Core 3 Preview 6 and 5.0.0-beta3-34 of GitVersionTask. Docker image is mcr.microsoft.com/dotnet/core/sdk:3.0.100-preview6 and I get the error below:

@thoemmi @adamshergold, do you mind giving a try to this version. Just curious if it works with .net core preview. After releasing GitVersion 5.0.0, I'll have a look on targeting the .net core 3.0 as well, but just curious if it works with the current version of GitVersion

[thoemmi]

It works, thanks a lot
(unfortunately, I first replied to the wrong issue)

[adamshergold]

@arturcic - yes, works for me too many thanks (apologies it took me a few days to check)
