MongoDB C# / .NET Driver

The MongoDB C# Driver is the 10gen-supported C# / .NET driver for MongoDB.

• C# Driver Tutorial
• C# Driver LINQ Tutorial
• C# Driver Serialization Tutorial
• API Documentation
• C# Driver README
• Source Code

Several other C# drivers have been developed by the community. This is the "official" C# Driver supported by 10gen. It is similar in many ways to the various drivers that came before it, but it is not a direct replacement for any of them. Most people have found it easy to convert to using this driver, but you should expect to have to make some changes.

Downloading the Driver

The C# Driver is hosted at github.com. Instructions for downloading the source code are at: Download Instructions

You can also download binary builds in either .msi or .zip formats from:
http://github.com/mongodb/mongo-csharp-driver/downloads.

Note: if you download the .zip file Windows might require you to "Unblock" the help file. If Windows asks "Do you want to open this file?" when you double click on the CSharpDriverDocs.chm file, clear the check box next to "Always ask before opening this file" before pressing the Open button. Alternatively, you can right click on the CSharpDriverDocs.chm file and select Properties, and then press the Unblock button at the bottom of the General tab. If the Unblock button is not present then the help file does not need to be unblocked.

Visual Studio Versions Supported

The current version of the C# Driver has been built and tested using

• Visual Studio 2010
• Visual Studio 2008
