Nini - An uncommonly powerful .NET configuration library

Homepage: Author: Brent R. Matzelle


Nini is an uncommonly powerful .NET configuration library designed to help build highly configurable applications quickly.


  • Take the DLL for your .NET Framework version out of the Bin directory
    • Bin\DotNet\1.0 - DLL built with the MS .NET Framework 1.0
    • Bin\DotNet\1.1 - DLL built with the MS .NET Framework 1.1
    • Bin\DotNetCompact\1.0 - DLL built for the MS .NET Compact Framework 1.0
    • Bin\Mono\1.1 - DLL built with Mono 1.1
  • Add the DLL as a reference in your project. In Visual Studio right-click on the References item in the project menu, click on the Browse button and select Nini.dll.
  • You can also add Nini to all projects on your machine by adding it to the global assembly cache. To do this run the following command: $> gacutil.exe /i Nini.dll
  • To check if your install was successful add the following to a .NET project file (this assumes C#, use the appropriate version for C++/VB.NET, etc):
  using Nini.Config;

If it compiles without any errors then you've succeeded.


There are several methods to build Nini. These builds all write files to the same directory structure as found in the INSTALL section above.

  • Visual Studio .NET At this time only a Visual Studio .NET 2002 solution file and project file are supplied. They are located in the Source directory (Nini.sln). To load this file simply double click the solutions and click Build -> Build Solution.

    • Building for the .NET Compact Framework This requires that you have Visual Studio .NET 2003 installed. Open the compact project file (NiniCompact.csdproj). Build the solution in the same way as documented above.
  • MonoDevelop / Xamarin Studio MonoDevelop IDE can also be used to build Nini for Mono on Linux (.NET 2.0 profile and more recent), and it's Windows equivalent Xamarin Studio - to build Nini for .NET (or also Mono).

  • NAnt ( In the Source directory there is a NAnt file. Here is how to build for each runtime from the command line:

    To build MS .NET Framework 1.0


    To build MS .NET Framework 1.1

    nant build-dotnet-1.1

    To build MS .NET Compact Framework 1.0

    *** There is no way to do this with NAnt at this time ***

    To build Mono 1.1

    nant build-mono

  • Note: If you would like to run the unit test then download and install NUnit (


  • You can find all documentation in the Docs directory. Here is a description of all directories beneath this directory: j Docs\Manual - Contains the Nini manual files. If you'd like to quickly get started with Nini then read this first.
    • Docs\Reference\chm - Contains the compiled reference documentation.
    • Docs\Reference\html - Contains the individual HTML-based reference.
    • Docs\Reference\xml - Contains the XML source for the reference documentation. If you'd like to add more documentation to the project then start here.


The Nini project contains some example applications to help you get started.
These files are located in the Examples directory.

  • NiniEdit This program is a fully-functional command line application that edits INI, XML, and .NET configuration file types. Reference the README.txt file for more information about it.


Go to the following places for help using Nini or if you'd like to request new features for Nini:


If your project (commercial or otherwise) uses Nini please let me know about it. I would like to post it on the project home page if possible.

Thank you for trying Nini!
