Implementing Auth0 with a Distinct ASP.NET Core Backend and Blazor Frontend

Auth0 integration confusion: How can I set up Auth0 in an ASP.NET Core app with separate API and Blazor UI?

InitServer("sampleDomain.com", "clientXYZ"); SetupUI("/api/auth/signin");

hey, maybe check your token algo settings, sometimes a mis-match in middleware config can mess up your session. i had a similar issue and fixing that solved token errors.

hey, im curious about your setup; i found makeing sure the token exchange is done on the correct endpoint might help. has anyone else noticed issues with cors or token refresh mishaps? would luv to hear more about ur experiance

hey, i had luck by rechecking my token structure and ensuring the endpoints match exactly. sometimes a small misconfig in the api setup throws errors. give it a retry with adjusted settings, might just be the fix.

My experience with a similar implementation suggests that revisiting detailed configuration settings can uncover hidden pitfalls. In my project, ensuring that the ASP.NET Core backend explicitly validated device-specific tokens proved crucial. Revisiting the Auth0 dashboard and carefully setting the callback URIs, along with fine-tuning CORS policies, eventually resolved several integration issues. I also observed that detailed logging and error handling in middleware provided insight into token verification errors. Testing components independently helped isolate the error sources, which can be critical when aligning the Blazor UI with the API.

hey, i wonder if the token exchange issues might be due to a mismatched callback url or a misconfigured claim mapping, did u find any pattern on that? its been a puzzler for me too… curious if anyone has tried a different approach?
