Describe the bug

When using the Build ASP.NET Core source code link in the readme, at the step of running restore ./restore.cmd you will see an error relating to requiring a minimum version of MSBuild for the current version of the .NET SDK.

Version 10.0.100-preview.2.25109.3 of the .NET SDK requires at least version 17.12.0 of MSBuild. The current available version of MSBuild is 17.8.5.5502

This is preventing the local build from running successfully.

Expected Behavior

It is expected that using ./restore.cmd on the cloned fork of the project would build the repository successfully.

Steps To Reproduce

Follow the instructions in Build ASP.NET Core source code and you should see the error at the ./restore.cmd step.

Exceptions (if any)

PS D:\repos\aspnetcore> ./restore.cmd
Building of C# project is enabled and has dependencies on NodeJS projects. Building of NodeJS projects is enabled since node is detected in C:\Program Files.
Note that if you are running Source Build, building NodeJS projects will be disabled later on.
