Can't create XmlMappingSource via FromReader method.

[Albert]

Hi,
I try to create XmlMappingSource dynamically with following code:

Code: Select all

            XNamespace ns = @"http://schemas.devart.com/linqconnect/mapping";

            XElement database = new XElement(ns + "Database",
            new XAttribute("Provider", "Devart.Data.Oracle.Linq.Provider.OracleDataProvider, Devart.Data.Oracle.Linq, Version=4.4.509.0, Culture=neutral, PublicKeyToken=09AF7300EEC23701"),
            new XAttribute("Name", string.Empty));

            var column = new XElement(ns + "Column", new XAttribute("Member", "Name"), new XAttribute("Name", "Name"));
            var type = new XElement(ns + "Type", new XAttribute("Name", "ObjType"), column);
            database.Add(new XElement(ns + "Table", new XAttribute("Name", "Obj$types"), type));


            DataContext dc = new Context(conn, Devart.Data.Linq.Mapping.XmlMappingSource.FromReader(database.CreateReader()));

And I get the following System.InvalidOperationException on last line of code:

Code: Select all

"Database node not found 'http://schemas.microsoft.com/linqtosql/mapping/2007', 'http://schemas.microsoft.com/linqtosql/dbml/2007' or 'http://schemas.devart.com/linqconnect/mapping'."}

When I create XmlMappingSource from static xml via XmlMappingSource.FromXlm method everything works fine!
Can you point me in the right direction?
Thanks!

Thank you for the report on this. We have reproduced this issue. We will investigate it in more details and inform you about the results as soon as possible.
As a workaround, please use the XmlMappingSource.FromXml method.

We have fixed this issue. The fix will be included in the next public build of LinqConnect, which we plan to release this week. We will post here when it is available for download.
