Could not load file or assembly Microsoft.DotNet.PlatformAbstractions under `dotnet tye`

See original GitHub issue

I see the following in logs for an azure-pipeline job for a dotnet core 3.1 application. These lines appear in the tye step of this pipeline.

Regardless of this error, the versions still seem to be updated correctly, for both the pipeline, dotnet assembly and node script. As such I post this here for informative purposes only.

I am working on removing the Microsoft.DotNet.PlatformAbstractions library. Before dotnet/sdk#11076, this library was implicitly loadable from MSBuild running on .NET Core. This was because the assembly was shipping in the dotnet\sdk\<version> directory. After dotnet/sdk#11076, the .NET 5.0 SDK no longer ships PlatformAbstractions with it.

So if your task relies on PlatformAbstractions, you will need to package the assembly with your task assembly (just like any other 3rd party library).

Alternatively, an API to get the current machine’s RID was added to .NET 5 with RuntimeInformation.RuntimeIdentifier. However, it is only available on .NET 5, and not previous versions of .NET Core, nor on .NET Framework.

@AArnott Get the same exception when try lastest daily builds of net5.0 sdk, and seems Microsoft.DotNet.PlatformAbstractions is already removed and no longer be an part of lastest daily builds of net5.0 sdk. https://github.com/dotnet/runtime/issues/3470 https://github.com/dotnet/sdk/pull/11076
