To make sure 'short' properties get formatted on the same line,
go to ReSharper -> options -> Code Editing -> C# -> Formatting Style -> Line Breaks and Wrapping
and on the right-pane , scroll all the way down to 'Other',
then tick the 'Place Simple property/indexer/event declaration on single line' option.
You would see the preview window changing from
class C
{
private int Property
{
get { return x; }
set { x = value; }
}
}
to
class C
{
private int Property { get { return x; } set { x = value; } }
}
