I made simple interface in Visual Studio 2010. When I launched application everything is bigger. Red square on screenshot represents size of the Button in launched application (On the right).
Am I missing something? How to fix it?

P.S.
In “Microsoft Expression Blend 4” the same project is exactly the same size as in editor.

    I’m not sure if this is a bug or not, but the basic idea here is that you have specifed a default size for your window, but because the control wants to be bigger (for whatever reason) it will automatically resize the window. Could be a bug how Visual Studio calculates window border size in the designer with the specified parameters as it’s incorrectly showing it as a bit smaller than when you actually launch your application.

    I would rather suggest that you avoid specifying heights/widths if possible. Instead set the Window to SizeToContent=WidthAndHeight. If you need to play with the size of your controls use Margins or MinWidth/MinHeight set directly on your controls.
