hello, I have a problem!
I have an infopath form and I want to connect into database,I use C# for coding behind, in the code I use below namespaces:
when I build the project, it shows me below error:
"The type or namespace name 'Data' does not exist in the namespace 'System' (are you missing an assembly reference?)"
I searched a lot, but I don't know how can I repair it? what is the exact namespace using instead of "Data" in VSTA(visual studio tools for applications)?
