Hi,

I have a DataSet defined in Visual Studio 2008 with an XSD file. The
contents are saved to an XML file using DataTable.WriteXml() and read back
using DataTable.ReadXml().

Now I am going to have to modify the schema. Specifically I want to replace
a boolean field with a (tristate) enumeration. Alternativly, I could leave
the existing field and add an additional field.

I will want to read files written with the old schema, but will only write
the new schema.

I have been looking for recommended practices for handling this kind of
problem. Although I have found general information about VSD versioning, I
have not found any information that relates to the use of DataSets in Visual
Studio 2008.

What would be the best practice to handle this case?

Thanks in advance
Phil

I should add that I am using a strongly typed DataSet.
