Today Blazor WebAssembly 3.2.0 Preview 1 has been released.

So I decided to update my Blazor project.

Just followed tutorial above and it took 10 minutes.

So you need to do the following:

1. Replace package reference in your project to 3.2.0-preview1.20073.1
2. Do some modification in Program.cs.
3. Delete Startup.cs.
