Gets the top-level extensibility object.

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

DTE DTE { get; }

Property Value

Type: EnvDTE.DTE
A DTE object.

In Visual Studio, the DTE object is the root of the automation model, which other object models often call "Application."

The following example demonstrates how to use the DTE property.

public static void DTE(DTE dte)
{
    // Setup debug Output window.
    Window w = (Window)dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput);
    w.Visible = true;
    OutputWindow ow = (OutputWindow)w.Object;
    OutputWindowPane owp = ow.OutputWindowPanes.Add("DTE Property Test");
    owp.Activate();

    EnvDTE.Expression exp = dte.Debugger.GetExpression("a", true, 1);
    EnvDTE.Expressions exps = exp.DataMembers;
    owp.OutputString("\nExpression count: " + exps.Count);
    owp.OutputString("\nEdition of the environment: " + exps.DTE.Edition);
    owp.OutputString("\nThe name of the current program: " + 
                     exps.Parent.CurrentProgram.Name);
    owp.OutputString("\nSecond expression: " + exps.Item(2).Name);
}
