The newer versions of RabbitMQ from https://www.nuget.org/packages/RabbitMQ.Client have issues with older version of DotNet and Visual Studio 2013.

I picked the highest release before 4.0 and at least the NuGet package installed.

Install-Package RabbitMQ.Client -Version 3.6.9

Trying to install anything after 4.0 will give the following errors:

PM> Install-Package RabbitMQ.Client -Version 5.0.1
