Add Support for Blazor

There has been a lot of interest in adding Blazor as a frontend option alongside Angular and React. This is something I'd like to add to the template, but I don't have a committed timeline for it yet.

Consolidating the following issues here:

• #1010
• #1054
• #1094

If Blazor support is important to you, please give this issue a thumbs up so I can gauge community interest.
