Add blazor + unity webGL support to the app

[sacOO7]

• Currently, the System.Net namespace doesn't allow code to be compiled and run on the browser as a sandbox.
• Read Direct Socket Access section under WebGL Networking.
• Need to find a way to inject external websocket library/ Json lib in order to get the app working on these platforms.

Seems https://github.com/endel/NativeWebSocket and https://github.com/psygames/UnityWebSocket supports webGL

[sacOO7]

Seems we can inject either of those libraries using TransportFactory as a clientOption

ably-dotnet/src/IO.Ably.Shared/ClientOptions.cs

Line 354 in c2a514a

public ITransportFactory TransportFactory { get; set; }

@sacOO7 is this on the roadmap please? I'd love to use Ably with unity webGL and with Blazor! Thx

[sacOO7]

@ApeOnFire not yet on the roadmap, but you should be able to support it by passing transportFactory https://github.com/endel/NativeWebSocket instance as per https://github.com/ably/ably-dotnet/blob/main/src/IO.Ably.Tests.Shared/Infrastructure/TestTransportFactory.cs

Also, you can raise ticket for the same on https://ably.com/support

That's brilliant, thanks @sacOO7 👍

[sacOO7]

@ApeOnFire if you can get this working, if possible, it will be great if you can raise a PR to add support.
Then we can review and merge it if needed.

@sacOO7 I'm not working on the project currently but sure - I'll happily to that when I do.

I'm hoping it will go ahead before the end of the year.

Hi Sachin,

Microsoft are charging a small fortune to use their Azure SignalR servers when you want to use their Blazor environment and the number of messages gets to production sized volumes.

Hence I was keen to check out the alternatives. Ably, although there is .net SignalR support it is really designed to be used by developers creating their own chat applications. Whereas Blazor pushes the Signalr implementation deeper into their lower levels so the developer doesn't need to worry about it. All they need to do is add a few lines to program.cs
builder.Services.AddSignalR(options =>
{
options.ClientTimeoutInterval = TimeSpan.FromSeconds(600);
options.KeepAliveInterval = TimeSpan.FromSeconds(15);
options.MaximumParallelInvocationsPerClient = 1;
}).AddAzureSignalR(); <-- HERE

I took a look at your sample code to try and implement a transport factory but got quickly lost.

Is there any guidance you could offer on how to implement a Blazor Signalr plugin that uses Ably instead? Setting up the Able connection was the really simple piece.

Best wishes
Paul

@jellysupport I will check and get back to you

@jellysupport can you raise the ticket at https://ably.com/support, so we can take a look at priority
