Save a document, project, or solution
On the File menu, click Save All (CTRL+SHIFT+S).
If this is the first time that you have saved a temporary project, you will be prompted for a project name and location.
If you have any documents open for editing in Microsoft Visual Studio 2008, they will not be updated in the Visual Studio 2008 window when you use Save All in Microsoft Expression Blend. However, the next time that you switch to your Visual Studio 2008 window, Visual Studio will display a prompt asking if you want to synchronize the changes that you made in Microsoft Expression Blend.
