.NET Core runtime 3.0 build errors on Windows

Hi,

I downloaded .NET Core runtime code successfully as follows:
“git clone https://github.com/dotnet/runtime.git
post that I go to “runtime” folder and do “build”, it reports below errors, I was able to do .NET Core 2.2 build using the same steps successfully. Any help to resolve these build errors would be highly appreciated.

I think you should create an issue about this on the dotnet/runtime repo. Doing that has a much better chance of getting a response from people who can help you.
