Generating a Schema from a DLL or Executable

The XSD tool also knows how to generate a an XSD from compiled types in a DLL or executable file. When generating a schema, xsd makes certain assumptions about the XSD types of instance variables. For any given CLR type, xsd chooses an XSD type for the schema. Table 8-2 lists each XSD type and its corresponding common language runtime type. In the cases where more than one XSD type maps to a single CLR type, the bold one will be used.
