Install and configure C# IDE

Downloading and configuring the C# IDE for the example template is the fourth step Overall Goals.

Install C# IDE

Download Rider or Visual Studio. If you prefer, you can also use a text editor, or a lightweight environment like Visual Studio Code.

Initial configuration of the project

Now, Open the project in your IDE or text editor. Do not worry if your IDE shows a lot of errors. They will disappear at the end of this section. There are a few steps to follow:

  • Open the .csproj file.

    • In Rider, right click on the project and go under Edit > Edit .csproj. Note that the image below is a sample image, and some information, particularly the name of the project, will not match with our Example mod project.


    • In Visual Studio Code, open up the .csproj file from the explorer view.

    • You can also navigate to the directory in which you cloned the git repository, and open the .csproj with a text editor.


If you can't find the .csproj file, make sure you are in the right directory. The project is organized in a nested structure. Here is an example directory structure. Note that the exact name of the .csproj file depends on what you passed as the name to dotnet new reactor -n when you created the project.

Inside the project file

In the .csproj file, there are few important properties:

  • GamePlatform defines game platform (Steam, Itch), defaults to Steam
  • GameVersion defines which version of the game that the Reactor framework will download.
  • Description should be a description of your mod.
  • Authors should be the name of the author(s) of the mod.
<Project Sdk="Microsoft.NET.Sdk">

<Target Name="Copy" AfterTargets="Build" Condition="'$(AmongUs)' != ''">
<Copy SourceFiles="$(TargetPath)" DestinationFolder="$(AmongUs)/BepInEx/plugins/" UseSymboliclinksIfPossible="true" />


If you still have any errors, you should refresh your IDE, and IDE should do this automatically. Otherwise, restart the IDE, and it will pick up the proper information from the project.
