Stuck on checking login state....

[mgermano75]

Hello,

I made a clone of the software, and dotnet run worked like a charm; I can login using My Azure Account, and the message "Hello Marco" in the upper right corner is correctly displayed, so that apparently login was successful; still, the program is stuck on "Checking login state..." message

If I go to Home Section, and Select current year and month, the app displays "An unhandled error has occurred. [Reload]" message

Would it be possible to add the error message, so that we can some hints about the cause of failure ?

Thank you

Regards

Hello sir, My name is Kevin Comba, I'm using this web application using the latest blazor WebAssembly and trying to implement this project with the Microsoft graph SDK, but am stuck on the state management section.

I think the error is on the event and how to invoke events while rerendering components. I'm new to blazor and dotnet in general an would love your support. Thank you

Hi @kelcho-spense

Thank you so much for reaching!
Could you please share the @code section of your Blazor Component AddEvent.razor

I think it's a small issue, but need more context to be able to help with getting it resolved.

Thanks

Thank @aksoftware98 for your quick response. Below is my GitHub with your project code. I'm trying to use the latest Blazor WAS with Microsoft dotnet graph SDK.

• remember the eventList.razor Component
  
• AddEvent.razor component it has the invoke function.
• Index.razor page it also has the overide void OnInitialized.
  I think this pages are the ones bringing the error above.

Also I have worked around "Stuck on checking login state" . I have made sure only access the home page when your logged in. The graph sdk is managing the login state. Currently I am unable to refactor your code to use graph SDK on MicrosoftCalendarEventsProvider.cs service. I would love to hear your input on this. I'm just a beginner trying to learn.

Okay well,
Here is the thing this code is very old, and I was new to Blazor and Blazor was new when I did it.
I will go over it tomorrow and make sure to get it to work with the latest version and I will the branch and comment back here about it.
Because this one is a little bit hard to follow compared to where Blazor is right now.
I will comment here with the link to the new branch within the next 48 hours
