I would like to know if it is possible to implement Microsofts Signalr library in a protocol solution. Signalr is a .NET library that allows for real-time updates from the server to the client and is made for ASP.NET (more information here). I am able to download the NuGet packages required, but I run into an issue where I am getting a ‘TargetInvocationException’ when running the code. I am not sure if this exception is happening because Signalr is meant for the ASP.NET framework or because there is a reference that I might not be aware of. Any help is appreciated. I have added a screenshot for reference.

Here is the exception:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.TypeLoadException: Method ‘DisposeAsync’ in type ‘Microsoft.AspNetCore.SignalR.Client.HubConnection’ from assembly ‘Microsoft.AspNetCore.SignalR.Client.Core, Version=7.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60’ does not have an implementation.
