Hi I know that debugging are not working in Rider so I am asking for tips on how your guys are handling debugging?

Are you not using Rider, and using something like VS Code or VS2019?

Do you debug in the browser.

I am looking for a workaround until Jetbrains fixes this

Hi Martin! 

For now, you could debug a Blazor application in browser by following the instructions on the official documentation site:
  • start the browser with the debug port enabled (e.g. chrome.exe --remote-debugging-port=9222 --user-data-dir=C:\Temp\remote-profile)
  • start the Blazor App in Rider (or in your terminal by typing dotnet run in the project directory)
  • press Shift-Alt-d

I hope this helps!

Hi,

is there an Update to Rider being able to Debug Blazor Wasm? Any Estimate when it will become available?

Thanks,

Thomas

Hi Thomas Schreiner,

We are currently working on it and plan to release Blazor WASM debugging support in one of the 2021.X releases. You can follow this issue to track progress.

Is blazor debugging an option?

I've just installed JetBrains Rider 2021.3 and I'm getting the error Cannot attach Blazor debugger.

I have tried with chrome and firefox.

Is there any guide on how to achieve this?

Hi,

For me it doesn't work either with the latest version of rider (2021.3.2). After some googling I was able to find blog articles telling that it is possible to debug blazor wasm apps, but I've had no success until now. How should I proceed?

 

Cheers

I am having the same problem on Linux with both firefox and chromium. I do not wish to install chrome if I can avoid it.

The error message reads "6:32 PM    Error running 'Client': class com.intellij.ide.browsers.firefox.FirefoxSettings cannot be cast to class com.intellij.ide.browsers.chrome.ChromeSettings (com.intellij.ide.browsers.firefox.FirefoxSettings and com.intellij.ide.browsers.chrome.ChromeSettings are in unnamed module of loader com.intellij.util.lang.PathClassLoader @13fee20c)"

Hello everyone! 

Sorry for the delay. I'm not sure that the reasons for your issues are the same. Do you still have such an issue with Rider 2022.1? 

Diego Martin it could be related to a known issue. However, there is not enough info to be sure. Please let us know if the issue is still there. 

Softozor please give us some more details of what doesn't work. Are there any errors? 

Georgios Antonopoulos could you please reproduce the case and create an issue with logs (that will be attached automatically) via Help | Report a bug?

 

Thank you in advance!
