You need to load the schema with a setting to allow DTDs (as the imported xmldsig schema references one):

XmlReaderSettings dtdSettings = new XmlReaderSettings();
dtdSettings.ProhibitDtd = false;

XmlReaderSettings settings = new XmlReaderSettings();

settings.ValidationType = ValidationType.Schema;
settings.Schemas.ValidationEventHandler += delegate(object sender, ValidationEventArgs vargs)
{
Console.WriteLine("Schema problem: Line {2}: {0}: {1}", vargs.Severity, vargs.Message, vargs.Exception.LineNumber);
};

settings.Schemas.Add(null, XmlReader.Create(@"schema.xsd", dtdSettings));
settings.ValidationEventHandler += delegate(object sender, ValidationEventArgs vargs)
{
Console.WriteLine("{0}: {1}", vargs.Severity, vargs.Message);
};

using (XmlReader reader = XmlReader.Create(@"file.xml", settings))
{
while (reader.Read()) { }
}
