Select the 'Pretty print' option (a button along the bottom of the browser with ''.

Select the 'AuthenticationService.js' file in this folder.

Find the '_content/.Authentication' folder in 'Sources'.

Load your PWA in the browser (I was using Edge at the time).

What I figured out is that I didn't need to plug in a complicated 'client assets' solution, I could simply drop the already formed JavaScript file into my project. This is essentially an aproach I had already tried using a heavy-weight process described in one of the links I included in the question above. The approach I took was to replace the auto-generated, obfuscated AuthenticationService.js file provided by Microsoft with a copy that is under my control, which I then instrumented with all the logging I needed. Well, I ended up finding a solution, so I thought I'd share. Does anyone have any wisdom to offer on how to troubleshoot / debug into this mass of C# interoping with obfuscated JavaScript? I've tried all the suggestions found on these pages:Īnd more. I've attempted to enable additional logging, I've attempted to trace into the code. I have tried everything I've been able to find to get some clues. However, I reached a point where I see my server returning a valid JWT from the token endpoint and the Blazor client fails almost silently, simply telling me 'There was an error signing in'. īetween having control over the server-side and the wonderful Developer Tools built into browsers (Chrome, Edge, etc.) I have quite a lot of helpful visibility into the system for troubleshooting.

So I built a simple reference implementation primarily following the guidance found here. Luckily for me Microsoft has officially released support for this scenario. My goal now is to create a Blazor WebAssembly Progressive Web App (or Single Page App depending on your preferred nomenclature) that uses my server for authentication. It is deployed and working well as an IP against relying parties, etc. I have built an OpenID Connect specification compliant Identity Provider authentication server.
