rethinkdb-net

Slava @ RethinkDB here. You might want to look at https://github.com/mfenniak/rethinkdb-net (this is an alternative C# driver with a different API). We'd love to get an official C# driver in soon, so if the community has suggestions on how to improve the API (and which driver feels more idiomatic), we're all ears!

Many core RethinkDB developers are huge fans of type safety. Check out the RethinkDB Haskell driver (https://github.com/atnnn/haskell-rethinkdb), and the .NET driver (https://github.com/mfenniak/rethinkdb-net). ReQL works really nicely with type safety (and will work even better when we let people declare optional schemas).

I'm the author of a .NET RethinkDB client (https://github.com/mfenniak/rethinkdb-net), and I can add that RethinkDB's lambda functions were very easy to implement in .NET by using C#'s expression tree feature (http://msdn.microsoft.com/en-us/library/bb397951.aspx). With that feature, a lambda can automatically be converted to an AST by creating a function that takes an Expression<Func<...>> parameter, which can easily be traversed and converted into RethinkDB's expression tree. Expression trees were introduced at the same time as LINQ, to support LINQ.

Mike @ RethinkDB here. Great feedback-- while we've been a bit behind in rolling out releases to other distros and languages, we've been delighted to see the community pick up our slack: - Our new build system has people successfully compiling from source and building community packages for CentOS, Slackware, Gentoo, Arch, and lots of other distros. - One intrepid soul is porting RethinkDB to FreeBSD, where it builds successfully (almost ready to merge in): https://github.com/rethinkdb/rethinkdb/pull/688 - We've seen an enormous number of client drivers for different languages pop up in a short time, with some impressive collaboration: * rethink-net (C#/.NET): https://github.com/mfenniak/rethinkdb-net * php-rql (PHP): https://github.com/danielmewes/php-rql * rethinkgo (Go): https://github.com/christopherhesse/rethinkgo

Mike @ RethinkDB here-- the document model is similar to MongoDB in that you store JSON documents, and there are no schemas, so it's not a relational database. Our query language (ReQL) does support a lot of SQL-like queries, such as group-by and JOINs, but there are no relations defined. It's also worth noting that a great team has sprung up to build a C# / .NET driver for RethinkDB (https://github.com/mfenniak/rethinkdb-net).
