Gets the top-level extensibility object.

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

Syntax

'Declaration
ReadOnly Property DTE As DTE

DTE DTE { get; }

property DTE^ DTE {
    DTE^ get ();
}

abstract DTE : DTE with get

function get DTE () : DTE

Property Value

Type: EnvDTE.DTE
A DTE object.

Remarks

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

Note

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).

Examples

Public Sub CodeClassExample(ByVal dte As DTE2)

    ' project and place the insertion point inside a class definition.
