XmlDataDocument is obsolete

Question

I was editing an old asp.net c# code and it shows this warning: XmlDataDocument is obsolete (but it is still working fine).

Should I keep that code as is? If not, how do I change is to a code which is not obsolete?

Answer 1

there is no direct replacement. it was xml exchange between ado datasets and xml.

as net 4.* is what is known as stable product (no feature changes), even though XmlDataDocument has been depreciated for over a decade, it is probably safe to use.

when you start your migration to net 6+, then you should recode.

Answer 2

XmlDocument Class shows .NET 6, but the app I was looking at is .NET 4.0. Does it need to be upgraded to .NET 6 first, or will XmlDocument Class work with .NET 4.0?
