SOLVED - XmlMappingSource.FromXml cannot load a mapping file generated by SqlMetal

Question

Hi,

I have a mapping file generated by SqlMetal, and when I try to instantiate a data context by passing that file, it gives me an exception which says something like "Root level node is invalid, line 1, position 1".

I just put two files, a map file and a datacontext file, generated by SqlMetal into my WCF service project.

Does anyone know why it happens? and how to solve this problem?

-database.map-

<?xml version="1.0" encoding="utf-8"?>
 <Database Name="DatabaseName" xmlns="http://schemas.microsoft.com/linqtosql/mapping/2007"&gt;
  <Table Name="dbo.answer_tbl" Member="Answer_tbl">
...Cointinue

-code-

var rootWebConfig = WebConfigurationManager.OpenWebConfiguration("/WebService");
        var connectionString = rootWebConfig.ConnectionStrings.ConnectionStrings["ConnectionString"].ConnectionString;
        using(var context = new DatabaseDataContext(connectionString, XmlMappingSource.FromXml("database.map")){
}

thanks in advance, Yoo

Edit

I found a solution at the following link.

I just needed to make the mapping file to an embedded resource.
