Hi all,

I'm using VS2008, I have this line of code in my page_load and I already added PresentationCore.dll to my reference but I'm getting the error message below.

RenderTargetBitmap rtb= new RenderTargetBitmap(180, 180, 120, 96, PixelFormats.Pbgra32);

This is the error message:

The type 'System.Windows.Freezable' is defined in an assembly that is not referenced. You must add a reference to assembly 'WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.C:\Documents and Settings\tfetalvero\My Documents\Visual Studio 2008\Projects\SilverlightProject1\SilverlightProject1\Page.xaml.cs2214SilverlightProject1

Thanks

From your path, it appears you are loading a Silverlight project? If so, VS 2008 does not support Silverlight projects, only WPF.

Just give the "WindowsBase" to the References.
(In "Solution Explorer" right-click on "References", "Add References...", and select the "WindowsBase" from ".Net" page.)

I had the same problem with my Autodesk Revit menu I add "WindowsBase" to my references and that solve my problems.
