C# and .NET MongoDB Driver

MongoDB C# / .NET Driver

The MongoDB C# Driver is the officially supported C# / .NET driver for MongoDB.

Note

Several other C# drivers have been developed by the community. This is the “officially supported MongoDB” C# Driver. 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 simplest way to get started is by using the nuget package. The package page will provide details on using nuget.

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 and .zip formats from https://github.com/mongodb/mongo-csharp-driver/releases

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.
