Visual Studio 2013 SDK で拡張機能を作りたい その5

前回に引き続き、サンプルプログラムと実行結果

[PackageRegistration(UseManagedResourcesOnly = true)]
[InstalledProductRegistration("#110", "#112", "1.0", IconResourceID = 400)]
[ProvideAutoLoad(VSConstants.UICONTEXT.SolutionExists_string)]
[Guid(GuidList.guidVSPackage4PkgString)]
public sealed class VSPackage4Package : Package
{
    /// <summary>Default constructor of the package...</summary>
    public VSPackage4Package()
    {
        var dte2 = Package.GetGlobalService(typeof(DTE)) as EnvDTE80.DTE2;

        var myOutWin = dte2.ToolWindows.OutputWindow.OutputWindowPanes.Add("ほげ");
        myOutWin.OutputString("♪ふが♪");

        Debug.WriteLine(string.Format("Entering constructor for: {0}", this.ToString()));
    }

どうやって動かすのか、一番悩んだ。
