Usage

Make Sure You Have the Original Minecraft JAR at <Your exe Path>/.minecraft/versions/<Minecraft Version>.
Download Forge Installer from Forge Offical Website. (Here)
Extract Installer (Using Code or Whatever).

Use whatevere the method to Convert "install_profile.json" to Installer.Forge.InstallProfile Object (e.g LitJson).

//Create InstallProfile Object
var installProfile= new Forge.InstallProfile();
using (var sr = new StreamReader("install_profile.json")) {
		try {
		    //Use LitJson to Convert Json String to Object.
		    installProfile = JsonMapper.ToObject<Forge.InstallProfile>(sr.ReadToEnd());
            sr.Close();
		} catch (Exception ex) {
		    Trace.WriteLine("[Error]Failed while Read" + ex);
		    throw ex;
		}
		if (installProfile == null) {
		    Trace.WriteLine("[Error]Failed.");
	    	sr.Close();
        }
}

Download all the nesseary libraries inside installProfile.libraries.
5.1 Notice that there are two libraries already included in Forge Install Jar (e.g: Forge 1.15.2-31.1.0)
"maven/net/minecraftforge/forge/1.15.2-31.1.0/forge-1.15.2-31.1.0.jar"
"maven/net/minecraftforge/forge/1.15.2-31.1.0/forge-1.15.2-31.1.0-universal.jar"
Copy these two file to ".minecraft/libraries/net/minecraftforge/forge/1.15.2-31.0.13" Folder.

Create Installer.Processor Instance.

  var processor = new Installer.Processor();
  
  //Set the Log Status.
  processor.LogStatus = Installer.Processor.LogLevel.Verbose;

Initialize Installer.Processor.

  if(processor.Init(Installer.Forge.InstallProfile, "Your Java.exe Path")) {
      //Begin Installation.
      processor.Begin();
  } else { 
      //Initialize Failed.
      //Do something here...
  }

Done!

Log Status

Processor allows you to set different Log Level.

Log Level	Description
None	Output Nothing. World is Clean.
InstallOnly	Output the Install Stage and Forge Installer's output.
Verbose	Output Everything including generated Java Args. It's Annoying.

Modify

IProgress<Installer.InstallTask> is not necessary, it can let processor report current stage. You can remove it from the code if you want.

Notice

The Forge Will be installed at the <Your exe Path>/.minecraft/versions/<Forge Version>. You Need to Change the Namespace Manully Due to These Code Was Export From BakaXL Source Code.
