Hello,

I´ve tested the following example:

http://msdn.microsoft.com/netframework/default.aspx?pull=/library/en-us/dnadonet/html/objectspaces.asp

but I get the following error when opening the MappingSchema:

Line 1 Position 2 is invalid.
Could not find schema information for the element 'http://schemas.microsoft.com/data/2002/09/28/mapping:MappingSchema'.

It seems that the schema could not be found. Any idea ?
