Setting up Visual Studio

Microsoft Visual Studio is a program (more specifically IDE, for Integrated Development Environment) for that makes it easier to code applications for Windows. For KSP, it is used for developing part modules via the C# IDE, although any app that can compile C# is sufficient.

Prerequisites

• Microsoft Windows XP or above
• Microsoft .NET Framework 3.5 or above
• Microsoft Visual C# Express 2010
  • You can also use Visual Studio 2010, which is functionally similar.
• Kerbal Space Program 0.14 X1 or above.

Setting Up

1. Close any solutions you currently have open by choosing File > Close Solution.
2. Start a new solution either by selecting New Project from the Home screen, or by using File > New... > Project...
3. Create a new Class Library project for C#. Name it whatever you like. (We're using MyKSPProject for this tutorial, so replace MyKSPProject with whatever you're using.)
   

   Setting up the class library project
4. In your Solution Explorer (the pane on the top right of the screen), right-click on MyKSPProject and choose Add Reference.
   

   Adding references
5. Switch to the Browse tab.
6. Find and add the following DLLs as references:
   • KSP_INSTALL_FOLDER\KSP_Data\Managed\Assembly-CSharp.dll
   • KSP_INSTALL_FOLDER\KSP_Data\Managed\UnityEngine.dll

Great, you're all set! Now continue to creating your first module!
