.NET Standard

Do you happen to have a list of the deps? I published a mostly empty project from Visual Studio referencing Microsoft.AspNetCore.SignalR.Client 1.0.1 (.netstandard 2.0) and thought that would be them all:

Microsoft.AspNetCore.Connections.Abstractions.dll
Microsoft.AspNetCore.Http.Connections.Client.dll
Microsoft.AspNetCore.Http.Connections.Common.dll
Microsoft.AspNetCore.Http.Features.dll
Microsoft.AspNetCore.SignalR.Client.Core.dll
Microsoft.AspNetCore.SignalR.Client.dll
Microsoft.AspNetCore.SignalR.Common.dll
Microsoft.AspNetCore.SignalR.Protocols.Json.dll
Microsoft.Extensions.Configuration.Abstractions.dll
Microsoft.Extensions.Configuration.Binder.dll
Microsoft.Extensions.Configuration.dll
Microsoft.Extensions.DependencyInjection.Abstractions.dll
Microsoft.Extensions.DependencyInjection.dll
Microsoft.Extensions.Logging.Abstractions.dll
Microsoft.Extensions.Logging.dll
Microsoft.Extensions.Options.dll
Microsoft.Extensions.Primitives.dll
Newtonsoft.Json.dll
SignalRTest.dll
System.IO.Pipelines.dll
System.Runtime.CompilerServices.Unsafe.dll
System.Threading.Channels.dll

but I still get the rather unhelpful "Unloading broken assembly Assets/Plugins/Microsoft.AspNetCore.SignalR.Client.Core.dll, this assembly can cause crashes in the runtime" (Unity 2018.1.6f1) - only a handful of these load in Unity

Thanks

 

Right, I figured out the dependencies in the end and SignalR Core works like a charm in the Unity Editor on Mac, yay!

However.. deployed to an iOS device I get the following when building the hub, any ideas?

(Filename: currently not available on il2cpp Line: -1)

 

Just an update for anyone reading, had another poke around at this. Turns out IL2CPP on my iOS build is stripping away "unused" parts of assemblies to save size (by using static analysis, which isn't clever enough to pick up on the DI used here I guess), this can be avoided by using a "link.xml" to ensure none of the ASPNetCore SignalR libraries are "stripped" and I've sorted the above issue now and can trigger Methods from iOS Client -> Server it looks like.

Next problem, the version of Newtonsoft JSON that SignalR Core uses - involves dynamic code generation which is prohibited on IOS so back to square 0 I think (as I'm now getting an error about 'system.reflection.emit' or similar not being implemented) - so currently can't handle method calls locally on IOS.

 

Use my version of Newtonsoft off the asset store.. it's free and fixes that issue by not using IL.Emit.

 

@echebkeso I'm having the exact same issue. What did you end up doing to fix the dependencies?

 

Current state of SignalR + MessagePack

I still find this error:

Unloading broken assembly Assets/Plugins/Microsoft.AspNetCore.SignalR.Client.dll, this assembly can cause crashes in the runtime
using Unity 2018.2.13f with this player settings:

Scripting Runtime Versione: .NET 4.x Equivalent
Scripting Backend: IL2CPP
Api Compatibility Level*: .NET Standard 2.0

The command used to download AspNetCore.SignalR.Client nuget is the following:

> Nuget Install Microsoft.AspNetCore.SignalR.Client -OutputDirectory SignalR

(tried with different version, preview too)

The Unload broken assembly errors happen also for some dependencies. Don't know how to solve. Maybe I have to wait Unity fixes the problem.

Someone solved?

 

When will 2018.3 be released out of beta?

 

We're looking to do the same thing at our company, bringing SignalR client libraries onto Unity.

I just tried it with 2018.3.0b3 (thanks Josh) and the error messages are more verbose, complaining about missing libraries. I added all the missing libraries and then brought them onto my main 2018.2.x project and it works. Only tested on MacOS Editor targeting iOS so far. Still have to go through IL2CPP.

I'm attaching the full set of libraries (I haven't pruned them, so some some may not be necessary) I needed to add in addition to Newtonsoft.Json:



I built the .dll on .NET 4.7.1 with Rider 2018.2.3

 

I am trying to do the same thing with SignalR using Windows Editor 2018.3.0b8 - but I can't see more detailed errors messages. I have a couple of assemblies that fail to load and a handful more that complains about crashes in the runtime.

Where should I be able to find the verbose messages?

@geretti: How are you creating your HubConnection?

 

@tg_sentio : with the sample code from here: https://docs.microsoft.com/en-us/aspnet/core/signalr/dotnet-client?view=aspnetcore-2.1

I would advise just including the libraries first, without even writing the test code, just to see if the Unity project compiles. I was able to see from the error logs (when opening the project) that assemblies were missing. That's how I compiled that list above.

 

I'm seeing issues on our test servers targeting 2108.1.9 only on Mac with .NET Standard 2.0 API compatibility, in that the project looks like it's compiling against a different API compatibility level. Was this issue ever resolved or explained?

 

Hi,
I am also working on the SignalRCore client application which fails on ios.
Thanks to @geretti 's screenshots, I have filled-up the Assets/Plugins directory. Everything works on Mac with Unity in-simulator, but I collect an error about DI on iOs. It seems I missed so module, but I cannot see how to solve it:

A suitable constructor for type 'Microsoft.Extensions.Options.OptionsManager`1[Microsoft.AspNetCore.Http.Connections.Client.HttpConnectionOptions]' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.

I fails while building a HubConnection object:

Code (CSharp):

1.            
2. Task.Run( () => {
3.                this.__conn = new HubConnectionBuilder()
4.                 .WithUrl("https://myapi.com/hub/", options =>
5.                 {
6.                     options.AccessTokenProvider = () => Task.FromResult(__token);
7.                 })
8.                 .Build();
9. [...] });
10.  

My link.xml:

    <assembly fullname="Microsoft">

        <type fullname="Microsoft.*" preserve="all" />

    </assembly>



  

    <assembly fullname="System">

        <type fullname="System.*" preserve="all" />

    </assembly>

    

Can anyone tell me what I should be missing?

 

@echebkeso, could you please share your link.xml file. It seems my problem is equivalent to the one you solved already...

 

Anyone ever get MessagePack integrated?

 

For future readers: I managed to get basic Signal R Core client up. Going to start looking at MessagePack next.

@fredczj Did you ever get it working?
