Is it possible to work with OrientDB using C#?

Question

Are there any implementations, api or examples of OrientDB and C#. The reason I am looking at OrientDB is becuase it's the only one that I found that is a combination of Graph and Document.

Any suggestions on how I should try this.

My next choice is RavenDB, but I am not sure if it supports joins or linked documents?

Any thoughts...
