/**== Custom Connection Implementations
*
* The client abstracts sending the request and creating a response behind `IConnection`
*
* By default the client will use a WebRequest based version on the desktop CLR (.NET 4.5 and up targets)
* and a HttpClient based HttpConnection specifically build for the Core CLR (netstandard 1.6).
*
* The reason for the split is because WebRequest and ServicePoint are not directly available on netstandard 1.6
*
* However the implementation written against WebRequest is the most matured implementation that we weren't ready to it give up.
* There are also a couple of important toggles that are easy to set against a `ServicePoint` that we'd have to give up
* had we jumped on the `HttpClient` completely.
*
* Another limitation is that `HttpClient` has no synchronous code paths and supporting that means doing hacky async patches which definitely
* need time to bake.
*
* So why would you ever want to pass your own `IConnection`? Let's look at a couple of examples
*
