Programmatically call MSBuild from C#

MSBuildHelper.3.5.cs

// Requires the following references:
// Microsoft.Build.Engine
// Microsoft.Build.Framework

using System.Collections.Generic;
using Microsoft.Build.BuildEngine;

public static class MsBuildHelper
{
  public static bool RunMsBuild(string projectFile, string target, IDictionary<string, string> properties)
	{
		Engine engine = new Engine();
		engine.RegisterLogger(new ConsoleLogger());
		BuildPropertyGroup buildProperties = new BuildPropertyGroup();
		foreach (KeyValuePair<string, string> property in properties)
		{
			buildProperties.SetProperty(property.Key, property.Value);
		}
		
		return engine.BuildProjectFile(projectFile, new [] { target }, buildProperties);
	}
}

I tried to get a pre compiled build from this code by adding
property.Add("OutputPath", @"c:\BuildDroplocation");
property.Add("DeployOnBuild", "true");
property.Add("WebPublishMethod", "FileSystem");
property.Add("PrecompileBeforePublish", "true");
However, it placed the build in output location without precompiled, is there any additional properties need to include?
