Rider + .Net 6 + Blazor Wasm - is it supported?

Dear Support,

I am giving a try to the Rider Ide, but running into multiple issues.

I have VS background.

I am using the latest EAP version:

JetBrains Rider 2021.3 EAP 10
Build #RD-213.5744.263, built on November 30, 2021

Issues with .Net 6 Blazor Wasm .Net Core hosted app

- Is there any save code and auto refresh in the browser feature when running without debugging, like VS? I am not seeking for hot reload (it would be the best). I could find only the dotnet watch profile as a solution, which is working.
- Is it possible to debug the Wasm code? And with the same hosting profile? With dotnet watch it doesn't start so I have to switch back to IIS always (which is unacceptable). Is this behaviour expected? Or can you suggest me any guideline?

- Furthermore when starting the debug with IIS the selected Edge browser it always starts with incognito, which is the suggested way as I read, but in this case every time the annoying Edge sync profile popup appears, I have to accept the cookies of my site and I need to login.. so make the whole process effectively useless. It doesn't happen with VS.

Another Ide related issue I posted to stackoverflow:
menu - Rider how to comment on other tab than the main? - Stack Overflow

Thanks,

Istvan

Dear Istvan,

The only option for now is using dotnet watch. However, there is a couple of known issues around it:

Yes, you can debug the WASM code, but it's not possible to do it along with `dotnet watch` running. We will hardly implement it in the near future - this is a tricky thing to do.

Furthermore when starting the debug with IIS the selected Edge browser it always starts with incognito, which is the suggested way as I read, but in this case every time the annoying Edge sync profile popup appears, I have to accept the cookies of my site and I need to login

The workaround here is to turn on Enable custom browser cli options in File | Settings | Build, Execution, Deployment | Debugger | Blazor WASM Debugging, and set custom user data directory in the Edge settings File | Settings | Tools | Web Browsers and Preview. Please note that this functionality is available only in Rider 2021.3, which will be released in a day or two.

Please let me know if you have any questions.
