How do I (on Windows 10) set up a Godot project to be developed in C# and export to web/html5?

Question

I've got the project set up and it exports fine to Windows. However, under Project -> Export I can't click the "Export Project" button.

When I click on the "Manage Export Templates" button, I'm prompted to install 3.0.6.stable.mono, which I download and install from the default mirror.

Unfortunately, this does not enable the "Export Project" button. Additionally, I get an error when from the main editor I attempt to "Run in Browser." It says "Could not open template for export."
