The provided adapter pattern allows to convert any object to any other supported type, as provided by the registered adapters. This package is a convenience grouping of all three separate pieces, for cases where you want to deploy all of them in a single project. ======= Example ======= IProject project = GetCurrentProject(); // say we need to use it as an MSBuild project, if possible IMSBuildProject msbuild = project.As<IMSBuildProject>(); if (msbuild != null) // do MSBuild stuff with it. ======= Adapters ======= public class ProjectToMsBuildAdapter : IAdapter<IProject, IMSBuildProject> { // Implement actual conversion. } The conversion behavior is now decoupled from the usage.
