Just checked in a new version of Simple-MongoDB that now runs against MongoDB v1.4.
It now also runs on an improved version of Newtonsoft’s Json.Net library, which has gained a improved BSON-writer and built in support for regex, hence my custom version of this lib is no longer necessary.
Go download and play with it and come up with suggestions and patches or why not join up and be a part of the team.
I will focus on implementing more/better querying support and write some examples of this. There’s hopefully also coming support for lazy-loading etc. via an add-on-project, by the help of Rei Roldan.
