Thank you. Can you please make a new video on how to add permissions to the access token (for cases when your app calls a downstream API)?
Thanks Claudio, my department is moving to Azure AD instead of Ping Federate as broker and this helps. Now I have to figure out how to get my tenant administrator to approve the app registration so we can actually log in - It seems that even though the permissions needed in the app registration say admin approval isn't required, I still get a notification after login prompt that admin must approve the app. I think this is because users aren't allowed to approve the app registration's usage of our data so it must be done at the tenant admin level? Ah well, just another gate to open. The other issue I had in an earlier version of this new app was DevOps pipelines that we normally use don't seem to work - publishing directly from VS works fine, but when deploying via DevOps there are errors in the browser and theme is broken. Once we have a development process that works well and can pump out apps efficiently, things change and we have to start from scratch! This is the life... :(
I understand migrating can be a great effort. Don't get discouraged, and work step-by-step. I didn't know that tenant admins have to approve new app registrations in certain scenarios. However, that makes perfect sense. I usually get the best results when I work with those admins and other people affected by the change rather than working against them. Explaining why we need certain things and what upsides they provide takes time and effort but usually leads to success. Good luck on your journey.
Great stuff. Thanks for the very clear explanation!!
Thanks, very kind of you.
Thanks for your tutorial!
Thank you. 🙂
How do i get the access token in blazor server app build with net 8?
Hi, thanks for sharing your knowledge. Can you tell me how to create role-based authorization in a Blazor Server application, please?
You can configure the roles as part of the [Authorize] attribute. The following article is a great starting point: www.c-sharpcorner.com/article/role-based-authorization-in-blazor/
Thanks for this. I modified your tutorial for the .NET 8 and Blazor Web App which currently doesn't have an authentication template yet... The Log in button gets hung, and there is a debug message that there was a type error "couldn't fetch" at "ai blazor.web.js". Logging in didn't appear to work until I hit the refresh button on the webpage... and I was logged in. Any suggestions on making the logging in a bit smoother?
Thanks for your feedback. I haven't tried it with .NET 8 yet. I might record a video once I figured it out. Meanwhile, you have the highest chance to fix your issue by putting the code on GitHub and asking fir help in a .NET community.
hi, how did you get this to work for .Net 8 blazor server when there isn't an option to choose 'microsoft identity platform' when creating a new blazor app?
Hi, for .net 8, when creating a Blazor App, there is no option to choose 'microsoft identity platform'. So how would I setup if that wizard window doesn't pop up?
Thanks for your question. I'm not very familiar with Microsoft Identity Platform itself. I also noticed that the current .NET 8 Blazor App project template does not provide this option. I think it's best to start with the official documentation. After all, it should only be a few lines of code to glue it all together. learn.microsoft.com/en-us/entra/identity-platform/
@@ClaudioBernasconi Apparently Microsoft Identity option will be added back again on .NET 9 in the official release on 11/2024.
Thanks man
You're welcome!
is it possible to set permission levels?
You can manage roles and other permissions in Azure AD and I'm sure you can check for them within your application. However, I have only authenticated users up to this point.
very nice video
Great 🎉 please add new video how to create app registration on azure portal
Dude, can you stop making these facial impressions like you are disgusted?
