When I open up an xsd file that includes other xsd files, all of the included files are added to a section called "Unauthorized zone". Visual Studio highlights the xs:include element and gives the following error when trying to resolve the schemaLocation attribute:
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've read the following blog post, but I'm not familiar enough with xsd yet to fully understand it.
Can anyone explain why this is happening or point me to a good resource that can help?
[Edit] All of the xsd files that are to be included are in the Visual Studio project.
For me it worked after going to the properties of the XSD file and clicking on Unblock. i got this answer from How do I modify my settings to allow VS2010 to load 3rd party XSD files from the "Unauthorized Zone"?
