Engine Class

Note: This class is new in the .NET Framework version 2.0.

Represents the MSBuild engine.

Namespace: Microsoft.Build.BuildEngine
Assembly: Microsoft.Build.Engine (in microsoft.build.engine.dll)

public class Engine
public class Engine
public class Engine

In a system of project-to-project dependencies, the Engine maintains the building projects, making it possible to avoid building the same target in the same project more than once in a given build.

The following example creates an Engine object and uses the BuildProjectFile method to build a project file. The FileLogger class is used to log information to a file.

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

namespace BuildAProjectCS
    class Program
        static void Main(string[] args)
            // Instantiate a new Engine object
            Engine engine = new Engine();

            // Point to the correct path that contains the 2.0 clr/tools
            engine.BinPath = @"c:\windows\microsoft.net\framework\v2.0.xxxxx";

            // Instantiate a new FileLogger to generate build log
            FileLogger logger = new FileLogger();

            // Set logfile parameter to indicate the log destination
            logger.Parameters = @"logfile=C:\temp\build.log";

            // Register the logger with the engine

            // Build a project file
            bool success = engine.BuildProjectFile(@"c:\temp\validate.proj");

            if (success)
                Console.WriteLine("Build failed - look at c:\temp\build.log for details");
