Microsoft.AspNetCore.Watch.BrowserRefresh causes Microsoft.NETCore.App.Ref 6.0 prebuilts

[MichaelSimons]

The Microsoft.AspNetCore.Watch.BrowserRefresh's net6.0 TFM is causing Microsoft.NETCore.App.Ref and Microsoft.AspNetCore.App.Ref source-build prebuilts in .NET 8.0.

.NET 8.0 source-build only produces the .NET8.0 targeting pack. All projects must reference a net standard or the net current TFM.

I am not familiar with this tool. Can someone help me understand why this needs to be pinned to the older supported net tfm?

Friendly ping.

The binary is injected into arbitrary .NET Core projects as a startup assembly. Since the SDK is backwards compatible with runtime versions, the assembly's TFM was pinned to .NET 6, the earlier version that supports this feature. Perhaps a workaround is to unpin the tfm during source build?

@pranavkm If we unpinned this during source build, does that mean that downlevel targeting in RH built SDKs would no longer be supported (in cases where this feature would be used?)

@pranavkm Any comments on this?

Gentle ping - this is affecting source-build prebuilts and I would like to see this resolved.
