Error with Blazor Server .NET 8 and Telerik.UI.for.Blazor 4.4

[Jonathan]

Hi all,

I've been trying to get new Blazor projects off the ground with Telerik 4.4, and had some luck with WASM but unfortunately Blazor Server I cannot get to work.

I have kept my projects simple, following the guidance set out in the Getting Started articles but every time run into the same error in the web client.

Error: Microsoft.JSInterop.JSException: Maximum call stack size exceeded
RangeError: Maximum call stack size exceeded

   at Telerik.Blazor.Components.TelerikMediaQuery.OnAfterRenderAsync(Boolean firstRender)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)

This stops any Telerik components from working, and leaves me a bit stuck!

Anyone seen similar? Or know of a workaround?

Hi Jonathan,

.NET 8 requires Telerik UI for Blazor 5.0. I highly recommend using 5.0.1 that includes another .NET 8-related fix.

Hi, 

I am having the same issue. I updated the Telerik Blazor UI to 5.0.1 but it did not solve the issue.  

Here are my current packages.
