Grpc-dotnet: "Detected package downgrade: Microsoft.NETCore.Platforms" when attempting to install Grpc.AspNetCore.Server from NuGet.

My project has 3.0.0-preview.19073.11 installed, and there is no Microsoft.NETCore.Platforms 3.0.0-preview3.19115.9 on NuGet. Because of this, I receive the error below when attempting to install Grpc.AspNetCore.Server 0.1.19.pre-1.

Detected package downgrade: Microsoft.NETCore.Platforms from 3.0.0-preview3.19115.9 to 3.0.0-preview.19073.11. Reference the package directly from the project to select a different version.

This should be resolved once the 3.0 preview3 SDK is available, which should happen shortly. The current package requires a nightly SDK.

Thank you, installing a daily SDK fixes this issue!

As an FYI, preview3 is now available- https://dotnet.microsoft.com/download/dotnet-core/3.0
