Befriend Twitter User oauth 1.1 in C#


I’ve got code to POST a tweet and GET a user timeline … but even following the order of signature items on always returns Error 400 - bad request. Also looking to SEARCH statuses by hashtag subject but the ill-conceived designers of oauth 1.1 have made it difficult as possible. Please don’t suggest using a library - haven’t seen a good befriend function in any 1.1. library. Only direct code in C# will do.
