Getting started with C# and the CouchDB API.
The project at http://code.google.com/p/couchbrowse contains a simple wrapper library for CouchDB, called SharpCouch, and a GUI client which makes use of the library. The GUI client code should serve as a good usage example, although the wrapper class is documented and fairly self-explanatory anyway.
You can get the source by issuing the following SVN command:
svn checkout http://couchbrowse.googlecode.com/svn/trunk/ couchbrowse
The project was built with SharpDevelop 2.2, but should work out of the box with Visual Studio 2005. Getting it to work with MonoDevelop should be reasonably easy, but has not been tried yet.
