Writing a Plugin class

In Visual studio right click "Class1.cs" in the solution explorer and rename it to "Plugin.cs". Choose "Yes" to rename all references

Copy and paste the following code into "Plugin.cs" replacing the entire contents of the file

using BepInEx;
using BepInEx.Unity.IL2CPP;

namespace MyFirstPlugin;

[BepInPlugin("NewbiePluginAuthor.MyFirstPlugin", "MyFirstPlugin", "1.0.0")]
public class Plugin : BasePlugin
{
    public override void Load()
    {
        // Plugin startup logic
        Log.LogInfo("MyFirstPlugin is loaded!");
    }
}

Save your changes by selecting File > Save Plugin.cs

Explaining how this work

We create a new class that inherits from the BepInEx BasePlugin class. We give this new class a special attribute (the BepInPlugin thing above the class) which BepInEx uses to make this class into a full-fledged plugin. The arguments we supply to the attribute include:

• The GUID: "NewbiePluginAuthor.MyFirstPlugin" This is an identifier which should uniquely identify the plugin. Typically just author.pluginname should suffice.

• The plugin name: "MyFirstPlugin"

• The plugin version: "1.0.0" This uses semantic versioning.
