Hello Shahin,

There is a simple way to prevent this if you are using db providers. just set your provider to a view instead of a table, in which you use ORDER BY road category. Setting the StartCap and EndCap properties of the pen to draw the line with to Round might help, too.

If you still feel you need to merge linestrings, have a look at NetTopologySuite. It has a LineMerger class.

Note: You will get faster results if you create a layer for each road category since you do not have to apply theming.

To enable outline you must set the EnableOutline property to true
