How do I debug a Blazor app with Rider?
Answered
When I run a Blazor app in Rider debug mode, it doesn't hit my breaking points. Actually the breaking points get sort of grayed out. The app runs fine in debug mode but I can't get it to hit my breaking points. I'm new to Rider and Blazor, by the way.
Thanks.

Hello Dave,
Would it be possible to provide an example showing the issue? Please also let me know what version of Rider you are using, your OS, more information about your app. Thank you in advance!
Sure.
I just created a brand new Blazor PWA app with the following dotnet command:
I set a breaking point on line 14 in the Counter component.
Then I clicked on the debug button in the top right corner. When the app runs in debug mode, I go to the Counter page and click on the button. It works but it doesn't hit this breaking point.
I get that No symbol instead of the red circle.
I just downloaded RIder for the trial. I will probably say goodbye to Visual Studio and VS Code and purchase RIder, but I really need to be able to debug Blazor apps going forward. I'm new to both Blazor and Rider so maybe something simple I'm missing.
I'm using a Microsoft Surface Book 2.
