Gsemac.Net.WebClientFactory.Default fails when attempting to get localization string for Method #10

Open CobaltGoldCS opened 1 year ago

CobaltGoldCS commented 1 year ago

Attached below are the relevant snippets of code

serviceProvider.GetRequiredService<IWebClientFactory>(); is the failure point, which seems to call WebClientFactory.Default in the background

EDIT:

I think I've tracked it down to the private WebClient constructor in the WebClientFactory, although I don't see anything in the constructor that would trigger an Exception like this

Do you have a stack trace I could look at? There shouldn't be any file system access going on here, so it's possible it's coming from elsewhere.

I have a feeling that its an assembly loading issue, which might be the fault of dotnet maui

Here seems to be the more relevant part

I have looked through the call stack, and the Gsemac.Net.Properties.DefaultHttpHeaders.get_Method seems to be causing the failure. Looking through DefaultHttpHeaders.Designer.cs I see a lot of generated code, which may be the culprit.

I wonder if the compiler cannot resolve ResourceManager, probably the "Method" string My hunch is that it's trying to load "" as an assembly file for some reason

It seems to be related to MAUI. I was able to find some some discussions related to this issue:

dotnet/maui#13784 dotnet/runtime#103994

It doesn't seem like it's getting any useful attention, though. I'll mess around with it and see if I can reproduce the issue and find some kind of workaround.

EDIT: I created a new MAUI app and attempted to instantiate a WebClient via WebClientFactory, and did not encounter any exceptions. I'm really not sure what's going on. 🤔

CobaltGoldCS commented 1 year ago

Looks like the bug only happens sometimes, which is even more bizarre 🤔.

Edit: It happens about 90% of the time for me, but sometimes it passes by fine.
