New Features:

This property will define if and in which direction AxisY will automatically add an additional step in order to ensure there is always a gap between the graph and the chart area top/bottom end. It is respected only when AutoRange property is set to true and IsZeroBasedProperty is treated with higher priority. The possible values are:

    • AxisExtendDirection.None - the Y axis will not be extended
    • AxisExtendDirection.Down - the Y axis will have an additional item at the bottom
    • AxisExtendDirection.Up - the Y axis will have an additional item at the top

The imported project "C:\Program Files\MSBuild\Microsoft\StyleCop\v4.3\Microsoft.Style.Targets" was not found ....

I was trying to open a Project for one of the Telerik source code projects and got the above error.

All what I had to do is just make sure VS SP1 is installed. That's it.


Hope this helps you,
