DotNetXtensions.Net (nuget): `XHttp` makes it easy to make 304 NotModified requests, to get rich request       response data in fewer lines of code, makes working with some annoying things       like FormUrlEncodedContent simpler, and so forth. Nothing earth-shattering here,       just something to simplify http coding a bit.
