Using Easy GIS .NET in your own Desktop Applications

While Easy GIS .NET Desktop Edition is a powerful GIS application on its own, its true power lies in the componentized design and ease by which developers can add the Easy GIS .NET controls to their own Windows desktop applications.

This page offers links to various examples of how you can use Easy GIS .NET Desktop Edition in your own .NET Windows applications, as well as instructions on how to add a reference to the Easy GIS .NET ShapeFile control to your Visual Studio projects.

Easy GIS .NET is written in C# using version 2.0 of the .NET Framework. In order to use the libraries in your own projects you will need to have version 2.0 or later of the .NET framework installed. All of the examples available to download include Visual Studio 2005 and Visual C# 2005 Express Edition solutions. The examples will also run in later versions of Visual Studio.

To download the examples click on the links to the left.

Including a reference to the Easy GIS .NET class libraries in your own projects

To add a reference to the Easy GIS .NET class libraries in your own projects perform the following steps.
