Visual Studio 2015 editor removes line continuation character in Visual Basic source code

Question

Visual Studio 2015 Pro gives the following error:

error BC36716: Visual Basic 9.0 does not support implicit line continuation.

For the following source code:

1     .Line.Points = New UnitPoint() _

2              {

3                New UnitPoint(Offset + OutlineBoxWidth_halph, 0),

4                New UnitPoint(Offset + OutlineBoxWidth_halph, "height"),

5                New UnitPoint(Offset + OutlineBoxWidth, "height")


6               }

When I insert continuation character on lines 2 to 5, the editor removes it when I move the cursor off that line

It used to compile fine but something has changed. What?

Answer 1

It was <LangVersion> in .vbproj.
