Could you:

• Check in the metadata TXT file generated when you run generate.ps1(details)

• Update api tag in AzSdk.RP.props, release notes in csproj

• Update versions in csproj and assemblyinfo.cs if you are going to release

Thanks

Thank you for your recent update. Can you make two minor changes, and we will be all good.

1. Update the version number in assemblyinfo.cs
2. Add some meaning release notes in the csproj. They will show up front and center on nuget to give user context on the new release of libraries. It is particularly helpful since the major version has changed.
