I want to use document toolkit for viewing office and pdf files in browser,
I create my first project step by step base on document toolkit guides. but I got error:
Resource not found on following line:
this.DataSource.PackageReader = new DefaultPackageReader(new Uri("Document Toolkit.xps", UriKind.Relative));

but this file already exist in root of my project.
what is the wrong with my project? please help me. I'm new in document toolkit and also silverlight :(
