SignalR version compatability (StatusCode: 405 'Method Not Allowed')

Question

I\'m having issues with a SignalR project I\'m currently working on. I\'m trying to build a server using .Net Core, and a client using traditional .Net (framework 4.6.1). Ho

You can't mix the .NET Core 1.x with the older client (1.x or 2.x). You will need to decide which is the best option for you but you need to implement the same compatible version across CLIENT and SERVER.

What’s Changed?

We added a number of new features to SignalR for ASP.NET Core but we also decided to remove support for some of the existing features or change how they work. One of the consequences of this is that SignalR for ASP.NET Core is not compatible with previous versions of SignalR. This means that you cannot use the old server with the new clients or the old clients with the new server.
