In this tutorial you will learn how to set up a solution, along with instructions on setting the output directory and files for more convenient building right into the Assemblies folder.

Requirements

• This tutorial requires you to have set up a Source and Assemblies folder.
  
  

Setting up a solution

1. Create a new class library project in your IDE of choice;
   1. Go to File -> New -> Solution;
   2. Go to C# or .NET -> Library or Class Library (NOT portable);
   3. Enter a project name (solution name automatically updated);
   4. Choose a location, preferably:
      

      (RimWorldInstallFolder)/Mods/(YourModName)/Source

   5. Optional: Untick "Create a directory for solution"/"Create a project within the solution directory",
2. In your project, add references to Assembly-CSharp.dll and UnityEngine.dll:
   1. Copy these files:
      

      (RimWorldInstallFolder)/RimWorld_Data/Managed/Assembly-CSharp.dll
      (RimWorldInstallFolder)/RimWorld_Data/Managed/UnityEngine.dll

   2. Place them in your project:
      

      (RimWorldInstallFolder)/Mods/(YourModName)/Source/(YourSolutionName)/Source-DLLs

   3. In your IDE project file browser, right-click the "References" folder and "Add reference";
   4. Choose the ".NET Assembly Browser" tab and "Browse", go to the folder you placed the copied DLLs;
   5. Choose both DLLs and click OK,
3. In your project properties, change the target framework to .NET 3.5:
   1. In your IDE project file browser, right-click "Solution (YourSolutionName)" or just "(YourSolutionName)";
   2. Choose Properties;
   3. Go to the "Compiling" tab, "Output", "Target framework", "Change" and choose ".NET Framework 3.5",
4. In your project properties, change the build events so only a single file is built:
   1. Change the debug info to "No debug information";
   2. In the References folder, right-click Assembly-CSharp -> Properties and change "Local copy" to False. Do the same for UnityEngine;
   3. Right-click your .cs files -> Properties and change "Copy to out" to Never,
5. In your project properties, fix the output location to put the DLL in the Assemblies folder:
   1. Change the output path to "..\..\Assemblies\".
