Project Constructor (Engine)


Initializes a new instance of the Project class using the supplied 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.

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

public Project(
	Engine engine


Type: Microsoft.Build.BuildEngine.Engine

The Engine instance to use for creating the project in memory.

The following example creates a Project object and uses the LoadXml method to add content to the project. The BuildItem, BuildItemGroup, and BuildItemGroupCollection classes are used to add, remove, and change items in the project.
