Vista - Request for the permission of type 'System.Security.Permissions.Fi

I've been trying to run XAML browser applications on the C drive using visual
studio 2005, but I receive the error
System.Security.SecurityException: Request for the permission of type
'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I have tried setting the trust level to full in the application
configuration file, and adding;

[assembly:FileIOPermission(SecurityAction.RequestMinimum, Unrestricted =
true)]

[assembly: PermissionSetAttribute(SecurityAction.RequestMinimum, Name =
"FullTrust")]

to the AssemblyInfo.cs file. I have also set intranet trust to full under
the .Net configuration tool.

Can anyone help me fix this error?
Thanks.

I have found the problem. In a resource dictionary file I was using, some of
the XAML referenced images using the full path name as shown below.


<ImageBrush Stretch="None" Viewport="0,0,128,128" ImageSource="C:\VS
Projects\FCI Logo 3\FCILogo_files\image0.png" TileMode="Tile"
ViewportUnits="Absolute">
<ImageBrush.Transform>
<MatrixTransform Matrix="1.33364,0,0,1.33667,-91.198,537.827"/>
</ImageBrush.Transform>
</ImageBrush>

When I changed the path to
ImageSource="image0.png"
it worked.
I don't quite understand why the error should have occurred anyway since the
file was on the local drive, not on a network. Also, does one have to change
the image references manually each time or can one get expression blend to do
it automatically?
