Describe the bug

Last week, I upgraded my Blazor Wasm PWA from .NET 7 to .NET 9. I tested everything, created a publish build and published it. It works without any problems.
So, I continued the work on the app and wanted to test something today. To do so, I created a publish build with <RunAOTCompilation>false</RunAOTCompilation>, simply because compilation is faster without AOT. The build was successful but the app cannot be loaded in the browser. One error message says, that Blazored.LocalStorage throws a Not Implemented Yet exception:

MONO interpreter: NIY encountered in method Blazored.LocalStorage.ServiceCollectionExtensions:AddBlazoredLocalStorage (Microsoft.Extensions.DependencyInjection.IServiceCollection)

So, I already started a bug report at the Blazored.LocalStorage github repo, but then found out that this package cannot be the (only) reason for the error. Let me explain:
In this case, 3 things can make the app crash:

  • I modified the code,
  • Blazored.LocalStorage is not ready for .NET 9 and
  • I changed with/without AOT

I tested all 8 combinations (with/without code changes, with/without Blazored.LocalStorage, with/without AOT). The only 2 cases, I can make the app run, are

  • without changes, without AOT, without Blazored.LocalStorage
  • with changes, without AOT, without Blazored.LocalStorage

Okay, it only works without Blazored.LocalStorage. That's why I first thought, this package causes the error. But it also does not work

  • without changes, with AOT, without Blazored.LocalStorage

So, I tried to go back to .NET 7, but without success. I cannot make the app run. That's a severe problem, because I cannot publish updates currently.

Here are some error messages

MONO interpreter: NIY encountered in method Blazored.LocalStorage.ServiceCollectionExtensions:AddBlazoredLocalStorage (Microsoft.Extensions.DependencyInjection.IServiceCollection) dotnet.runtime.o8gq1i8bk6.js:3 [MONO] * Assertion: should not be reached at /__w/1/s/src/mono/mono/mini/interp/interp.c:3965

There is a bug report, that is similar to mine, but no solution is provided.

Any help is highly appreciated, because I cannot continue working.
Please let me know, if you need any information.

Many thanks
