Is this with version 5.1.1 of GitVersion?

[Caleb9]

@asbjornu I'm experiencing the same issue and yes, it's version 5.1.1 installed through chocolatey (we're printing out GitVersion's version for diagnostics, see below). Seems it was able to calculate the version but failed during log generation?

Is this with version 5.1.1 of GitVersion?

Yes, installed via Chocolatey, as @Caleb9 commented out.

[Caleb9]

Still happening on 5.1.2.

[warning-explosive]

Works fine with GitVersion 4.0.0 in AppVeyor build

I've tested a bit with AppVeyor.

The issue I believe has to do with the dependency System.ComponentModel.EventBasedAsync.dll missing in GitVersion's published package (or trimmed?). I will admit I don't know enough of how self-contained/trimmed packaging works, but it seems odd that after inspecting the with GitVersion included System.Net.WebClient.dll with IlSpy, it seems not to be referencing System.ComponentModel.EventBasedAsync.dll whereas every other assembly I inspect does.

The dependency graph is:

GitVersionCore -> System.Net.WebClient -> System.ComponentModel.EventBasedAsync.dll

All that said, it seems it is able to resolve the correct assemblies from older preinstalled runtimes on the VS2017 image, but not on VS2019 because of the missing older runtimes.

On that note, would it be an idea to transition to newer API's like HttpClient? Or is there a specific reason to stay with WebClient?

[skwasjer]

Ignore my last, it would require significant refactor due to async nature of HttpClient.

[Jericho]

I confirm that I am also seeing this issue with GitVersion.CommandLine version 5.1.2. Another of my projects is using GitVersion.CommandLine version 5.0.1 and is not experiencing this problem.

Also, I can confirm that I am not experiencing this problem when running my build script locally:
