Workaround

If you add the nuget package System.Memory 4.5.0 it works !

Why nobody verify this bug ? The bug exists since September 2021.

I can confirm that this issue is "back". It seems not to be the exact same issue which I encountered earlier this year with Android on Visual Studio 2022 Release however it does looks similar. The Android issue disappeared - I think - by using the Preview version of Visual Studio 2022. I just started having a look at the iOS version and there it is again. I tried the Visual Studio 2022 v17.3 Preview but I can't deploy to iOS or Android at all with this version :-/.

Error during SignalRHub.StartAsync() System.MissingMethodException: Method not found: Microsoft.AspNetCore.Http.Connections.NegotiationResponse Microsoft.AspNetCore.Http.Connections.NegotiateProtocol.ParseResponse(System.ReadOnlySpan1<byte>)

I have been working on/off on this issue for the last few days. In the end - somehow - the well known System.Buffer and System.Memory workaround made it work for me (see 1, 2, 3). It never had before for the earlier problem.

Interesting information

  • Using Visual Studio 2022 v17.2.5
  • Setting the xamarn shared project back to SignalR v5.0.14? (or similar) generated the "old" error message I had with Android earlier this year.
  • It now works (with the mentioned workaround) for SignalR 6.0.6 (newest at the moment).
  • Xamarin shared project is set to .NET Standard 2.0
  • Turning Hot Reload off did not help (Xamarin iOS only or even all Hot Reload).

When did it start to work? I cleaned the solution, removed all \bin and \obj folders manually (to make sure), modified the three csproj files by hand with the following entries:

<PackageReference Include="System.Buffers" Version="4.5.1" IncludeAssets="none" />
<PackageReference Include="System.Memory" Version="4.5.4" IncludeAssets="none" />

I started the Studio, rebuild (twice or so) and started the iOS app in the "simulator". It worked. I checked with the Android emulator which is also still working.

So far so good. Unfortunately Xamarin is a lot like magic. It works now, it might work five builds from now but somewhere it might also just stop working. So lets hope for the best.
