We're working on that. Hopefully I can find some spare time to target .net core 3.0 as well

@ladeak can you try version 5.0.2-beta.1+95 when it gets indexed?

[ladeak]

I can give it a try next week.

Trying to use GitVersion dotnet tool with .net core 3 sdk.

The 5.0.2-beta.1+95 throws a new exception:

Unfortunately the mcr.microsoft.com/dotnet/core/sdk:3.0 image uses the Debian10 version that the library we rely on does not yet support. What I did as workaround in the PR for .net core 3.0 feature is I added .net core on top of a debian 9 that is supported and installed dotnet core and then the global tool works.

[ladeak]

Ah, currently I am using the GitVersion (preview) task in AzureDevOps. Does that auto-pick up the new version as well? Or is there a way to "force" it to download the latest tool?

[arturcic]

Can you try the new preview extension?

[ladeak]

@arturcic I tested the beta package, looks good on my end. Thank you for the quick turnaround.

[arturcic]

Great, we'll be deprecating the old extension (GitTools/GitVersion) in favor or the new one (GitTools/UseGitVersion)

[sheldonhull]

Is there anyone reason a new extension was needed instead of bumping the major version? I found it disruptive on the builds as I now have to update the actual extension instead of just GitVersion@5 for example? I'd like to understand if there is a limitation to the existing versioning as I've used that in the past with extensions to handle those breaking changes

[arturcic]

The reason is the way we are publishing the tool has changed. Previously we were embedding the tool with all dependencies for all supported platforms, meaning it was a huge extension in size and we got to the size limit for an extension. We change the approach and now we install the tool from nuget as global tool. It's basically a new extension
