Note: This API is now obsolete.
Represents the MSBuild engine.
MSBuild is now included in Visual Studio instead of the .NET Framework. You can use MSBuild 12.0 side-by-side with versions previously deployed with the .NET Framework.For more information, see What's New in MSBuild 12.0.

Remarks
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.
Examples
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.
Module Module1
    'Add references to Microsoft.Build.Framework and 
    'Microsoft.Build.BuildEngine 
    Sub Main()
        'Create a new Engine object 
        Dim engine As New Engine()
        'Point to the path that contains the .NET Framework 2.0 CLR and tools
        engine.BinPath = "c:\windows\microsoft.net\framework\v2.0.xxxxx" 
        'Instantiate a new FileLogger to generate a build log 
        Dim logger As New FileLogger()
        'Set logfile parameter to indicate the log destination
        logger.Parameters = "logfile=c:\temp\build.log" 
        'Register the logger with the engine
        engine.RegisterLogger(logger)
        'Build the project file 
        Dim success As Boolean = engine.BuildProjectFile("c:\temp\validate.proj")
        'Unregister all loggers to close the log file
        engine.UnregisterAllLoggers()
        If success Then
            Console.WriteLine("Build succeeded.")
        Else
            Console.WriteLine("Build failed. View C:\temp\build.log for details.")
