This page is a quick reference for how to use Visual Studio 2017 or MonoDevelop/Visual Studio for Mac when creating or editing a SMAPI mod. See Modding:Modder Guide for the main guide.

Before you start

  • You should install Visual Studio 2017 Community (Windows), MonoDevelop (Linux), or Visual Studio for Mac (Mac).
  • Reviewing C# Fundamentals for Absolute Beginners is strongly recommended if you're new to programming C#.
  • Here are some basic terms to remember:
    term definition
    IDE The program used to edit, run, and compile your code (short for Integrated Development Environment). The main IDEs are Visual Studio on Windows, and MonoDevelop/Visual Studio for Mac on Linux/Mac.
    DLL The file with a .dll extension which contains your compiled code (short for Dynamic Link Library). This is the file that SMAPI reads when loading your mod.
    project A collection of source code + configuration + resources (like images) you edit in the IDE. Each project is compiled into its own DLL.
    solution A collection of projects with some global settings. The solution itself isn't compiled, but it enables some convenient features (like letting projects easily reference each other).

Create a mod project

Before you can write your mod code, you need to create a solution and project to contain it.

In Visual Studio 2017

  1. Open Visual Studio 2017.
  2. Click File » New » Project from the menu bar:
     
  3. In the 'New Project' window, choose Visual C# » Class Library (.NET Framework):
     
  4. Enter a descriptive mod name. By convention, the name should be one word with mixed caps (like "PineapplesEverywhere"):
     
  5. Make sure "create directory for solution" is checked, and click OK:

In MonoDevelop

  1. Open MonoDevelop.
  2. Click File » New Solution from the menu bar:
     
  3. In the 'New Project' window, choose .NET » Library and click Next:
     
  4. Enter a descriptive mod name. By convention, the name should be one word with mixed caps (like "PineapplesEverywhere"):
     
  5. Make sure "create a project directory within the solution directory" is checked, and click Create:
     

In Visual Studio for Mac

  1. Open Visual Studio for Mac.
  2. Click File » New Solution from the menu bar:
     
  3. In the 'New Project' window, choose .NET » Library and click Next:
     
  4. Enter a descriptive mod name. By convention, the name should be one word with mixed caps (like "PineapplesEverywhere"):
     
  5. Make sure "create a project directory within the solution directory" is checked, and click Create:
     

Set the target framework

The 'target framework' is the version of .NET Framework your code uses, which affects the version needed to run your mod. The recommended target framework is .NET Framework 4.5, which is the version SMAPI itself targets.

In Visual Studio 2017

  2. From the Solution Explorer, right-click on the project and choose Properties:
     
  3. On the Application tab, change the Target Framework dropdown to .NET Framework 4.5:
     
  4. A dialogue may appear asking you to confirm the change. Click 'Yes' to confirm:
     

In MonoDevelop/Visual Studio for Mac
