Microsoft's own version of document-oriented database? [closed]

Question

recently, I have been experimenting an open source document-oriented database named MongoDB and found it fascinating.

it's super fast with dynamic schema, I don't have to do much normalization to increase productivity. It also gets along with asp.net/asp.net mvc.

So I can't stop wondering if Microsoft is going to make it's own document-oriented database?or there is one already?

a performance comparison between MongoDB and SQL server 2008. http://www.michaelckennedy.net/blog/2010/04/29/MongoDBVsSQLServer2008PerformanceShowdown.aspx

Answer 1

You might be interested in RavenDB. It's not directly from Microsoft, but it is specifically targetted at the .NET/Windows platform.

MongoDB support in .NET is also excellent.
