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

Answer 2

The last .NET 4.0 support for SignalR is version 1.2.2. Version 2 only works with .NET 4.5

Open the NuGet Package Manager Console and type:

Install-Package Microsoft.AspNet.SignalR.Client -Version 1.2.2 Install-Package Microsoft.AspNet.SignalR -Version 1.2.2  

This will install the SignalR (Client and Server) in your selected project (web project) automatically.
