Sorry for my delay. Had been on holidays. Hmm. I can see that you do not get any exceptions. I upgraded all nugets to the latest version (as you can see in the attached csproj). Also i upgraded the visual studio to the latest version. Still ...

MudblazorExt4Maui.csproj.zip

Please tell me what else i can provide to you in order to make this work.

Hard to say but maybe you can firstly paste the full callstack here

[whann0205]

Sorry i am fairly new in the .net c# world. What do you mean by saying "paste the full callstack"?

I fixed one reference issues that can cause the error. Can you maybe try it again with the preview package 2.0.6-prev-2410112222-main

<PackageReference Include="MudBlazor.Extensions" Version="2.0.6-prev-2410112222-main" />

[whann0205]

I have tried it again, but unfortunealy the error persists.

Also cleared obj and bin first and rebuilt the whole solution to no avail. You can clone the updated solution from (https://github.com/whann0205/MudblazorExt4Maui)

Also did test the solution on my mac m1. I tried first to compile with maccatalyst it compiles and runs without any problem! Then i tried with android So the problem is definitely related to android not necessarily machine centric!

I still cant reproduce, can you please test this version?

<PackageReference Include="MudBlazor.Extensions" Version="2.0.6-prev-2410121210-main" />

[whann0205]

I am happy to tell you that it works with that version!!

[fgilde]

That makes me happy. Great. I create a release later this day and close the issue then afterwards

Fixed in MudBlazor.Extensions 2.0.6 Nuget
