The .NET SDK 5.0.100 Preview 3 includes .NET 5.0.0 preview Runtime so downloading the runtime packages separately is not needed when installing the SDK.

`dotnet --version`

Your feedback is important and appreciated. We've created an issue at [dotnet/core #4607](https://github.com/dotnet/core/issues/4607) for your questions and comments.
