I was running into issues trying to deploy my app with Mindfusion diagrams to the free Azure tier. So I tried the same with the demo app you supplied (MinApp, .NET10) and I ran into the same issues.

The app runs fine locally, but when deployed, when you attempt to load a page with a DiagramView, in dev tools you can see errors trying to load libSkiaSharp library and its dependencies:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: libSkiaSharp
System.DllNotFoundException: libSkiaSharp
   at SkiaSharp.SKPaint..ctor((index))
   at Microsoft.Maui.Graphics.Skia.SkiaCanvasStateService.EnsureDefaults((index))
   at Microsoft.Maui.Graphics.Skia.SkiaCanvasStateService.CreateNew(/Object context)
   at .....

I'm pretty sure the Skia libs are a dependent of Mindfusion. I think it's as simple as instructing the site how to load the libs - as far as I can tell, all of the libs, wasms, etc are deployed to the server, but I guess they are not found.

i realize this is not really a Mindfusion issue - just a deployment issue, but I was hoping you might have some insight.

You can view the app at:

I dd manage to deploy your balzortablenodes app on .net8, so I think I'll refactor for .net8.

I'm pretty sure the issue is with the Azure runtime env.

Thanks very much!!! These configs worked with the sample code and with my actual real app under development.

I thnk it's the MIME defs in the web.config.

Thanks again
