SignalR support in .NET 4

Question

Does SignalR support .NET 4.0. Or is it support only from .NET 4.5 upwards. Is there any link which provides with minimum requirements for SignalR.

Answer 1

This is not the case any more, and the 2.x releases require .NET 4.5. https://github.com/SignalR/SignalR/issues/1723
