Answer 1

Ctrl + D is a new shortcut introduced in VS 2017 v15.6 that seems to do the exact thing that Ctrl + E, V

Ctrl + D will duplicate the line the cursor is in and insert it right below the line in focus. If you’d like to duplicate a specific set of code, simply select the portion of code you want to duplicate before invoking the duplicate code command.

It won't affect your clipboard

Here's a macro based on the one in the link posted by Wael, but improved in the following areas:

• slightly shorter
• slightly faster
• comments :)
• behaves for lines starting with "///"
• can be undone with a single undo

Imports System
Imports EnvDTE
Imports EnvDTE80

Public Module Module1

    Sub DuplicateLine()
        Dim sel As TextSelection = DTE.ActiveDocument.Selection
        sel.StartOfLine(0) '' move to start
        sel.EndOfLine(True) '' select to end
        Dim line As String = sel.Text
        sel.EndOfLine(False) '' move to end
        sel.Insert(ControlChars.NewLine + line, vsInsertFlags.vsInsertFlagsCollapseToEnd)
    End Sub

End Module

If you like eclipse style line (or block) duplicating using CTRL+ALT+UP or CTRL+UP+DOWN, below I post macros for this purpose:

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics

Public Module DuplicateLineModule
    Sub DuplicateLineDown()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        lineNumber = selection.TopLine
        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.EndOfLine()
        selection.Insert(vbNewLine & line)
    End Sub
    Sub DuplicateLineUp()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        lineNumber = selection.BottomLine
        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.Insert(vbNewLine & line)
        selection.MoveToDisplayColumn(lineNumber, 0)
    End Sub
End Module

for Visual Studio 2012, 2013, 2015, 2017 follow the link and download the extension

https://marketplace.visualstudio.com/items?itemName=ctlajoie.DuplicateSelection

Now go into Tools > Options > Keyboard, and type "Duplicate" in the search box (the full command string is "Edit.DuplicateSelection"). Here you can bind it to any shortcut in the same way you would for any other command.

Answer 5

VS 2017 its Ctrl + D or Ctrl + C ; Ctrl + V they both work for me.

Answer 6

In Visual Studio 2013 you can use Ctrl+C+V
