New C# Wrapper : PUT request: BadRequest?

[ThomasGugler]

I am working on a C# Wrapper that works with WPF, Silverlight and for
sure Windows Phone7,
and im going to use the nice REST opensource library hammock (http://
hammock.codeplex.com)

OAuth works...also the GET requests (/me, /me/tracks..) do work :)
but POST requests do not :(
in particular neither creating a new playlist nor uploading a new
track..

method "AddTrack" and "CreatePlaylist":
i always get a server Bad request...the correct Addfile, AddParameter,
AddHeader...thats the problem i think?

thanks for any help in advance!
=> email me if any anyone can help ...i could send a working
testclient for debugging purpose.

Thomas

Hi Thomas!

For file uploads you must send a "Content-Type: multipart/form-data"
header. Also this request requires a string for the track[title] and a
file for the track[asset_data] parameters.

I am not familiar with the library you're using but I'd imagine that

request.AddFile("name","fileName", @"C:\Users\Thomas\Music
\Soap and Skin - Spiracle.mp3");

adds the file to the request as the parameter "name" which then should
be "track[asset_data]"

When posting xml as the request body you must send a "Content-Type:
application/xml" header.

Is there support for OAuth 2 in Hammock? Please read about our support
for OAuth 2 here: https://github.com/soundcloud/api/wiki/13-X-OAuth-2

Cheers,
