See the Install on Windows tutorial for more information on how to install and run the database for the first time.
See the Windows Service page.
Get pre-built binaries on the MongoDB Downloads page. Binaries are available for both 32 bit and 64 bit Windows. MongoDB uses memory-mapped files for data storage, so for servers managing more than 2GB of data you will definitely need the 64 bit version (and a 64 bit version of Windows).
The Windows 2008 MongoDB build uses newer features of Windows to enhance performance. Use this build if you are running with 64-bit Windows Server 2008 R2, Windows 7, or greater.
You can write apps in almost any programming language, see the Drivers page. In particular C#, .NET, PHP, C and C++ work just fine.
We recommend using the pre-built binaries, but MongoDB builds fine with Visual Studio 2008 and 2010. See the “Building for Windows using Visual Studio 2008” and “Building for Windows using Visual Studio 2010” pages.
