So we encounter a bug we can't figure out how to resolve. We are using signalR (Core) to have the server send data to connected clients. The servier is an API with .Net Core 3.1 and the clients are UWP clients. In debug mode all is working fine, but when we create a release of our client the SignalR connection failed.
Here is the code of the connection :
var connectUrl = await ControllerManager.Instance.GetAsync<string>($"Signalr/connectionurl");
var token = ControllerManager.Instance.EchinoBearerToken;
_chatHubConnection = new HubConnectionBuilder()
.WithUrl($"{connectUrl}/signalr/chathub", options => {
options.AccessTokenProvider = () => Task.FromResult(token);
})
.Build();
The error :
Microsoft.AspNetCore.HttpConnections.Client.HttpConnectionOptions on Microsoft.Extensions.Options.OptionsManager [TOptions] violates the constraint of type TOptions
Parameter name : GenericArguments[0[
And here is the stack trace of the fail:

The last occurence of our file in the stack trace is the ClientMessageService.cs:line 52. It's the code pasted
The Min version of UWP is Windows 10 Fall Creators Update and the Target version is 1809 build 17763.
Can anyone help us resolve our issue? Feel free to ask for additional informations.
Thanks a lot
