Request for adding UWP support about authgear-sdk-xamarin HOT 8 OPEN

@louischan-oursky I'm getting invalid device info error after authentication. Seems server is validating device info :( Should I put a dummy android device info for now? I reckon you guys wouldn't have time to update server to add a windows to device info field.

You can use dummy values during development. It would be great if you can help implementing device info for Windows devices :)

I'd love to but I think I don't have time to setup server development environment 😅 I will setup dummy value for now.

UWP AuthenticateAsync is done. Since UWP's system authentication API uses old edge's engine (spartan) which is no longer supported by most sites (authgear is tested to be unsable), system browser is used instead.

Still working on Uno WASM support and it requires major code structure change as there is no specific WASM TFM. To reference Uno's polyfill of Windows API, a special project Authgear.Xamarin.Wasm is created side-by-side with the original project to create a cross-runtime library. Essentially, it's an additional binary built with uno's windows API polyfill located in a specific folder in the nuget. I have not tested how it works but I guess uno has specific build time logic to pick the binary up.

Uno also provides Xamarin WASM support (experimental). I have created a test project but apparently cross-runtime library only works in nuget. Referencing the project doesn't work (no WASM output), and referencing the wasm project directly produces type conflict (duplicate definition). Will proceed to create local nuget to test.

The local nuget can be created as expected, but the WASM specific content isn't picked up. Manually moved the nupkg to another project for consumption and again WASM specific content (e.g. AuthgearSDK constructor) isn't picked up. I have inspected the nupkg and resultant dll, can confirm the WASM specific content are all there, which means it's the build process that didn't pick it up.

Asked in discord for troubleshooting tips.

Pending reply.

• Support cancellation token in UWP as it's now logging in in external browser and the app has no way to "go back"
• Exclude uno from nupkg dependency (set private assets = all)

from authgear-sdk-xamarin.

They replied. Basically, due to WASM not being a specific TFM, there is no way to pick up WASM specific method.

The solution I will employ is to create a "general" method in .netstandard.cs that accepts object and cast the object to the correct type. WASM project can then pass any required param to the method. Unfortunate situation, yes, but workable.
