Visual Studio won't update properties of my Data Source

Question

I am using my class "Invoice" as a Data Source. But after adding more properties to it, Visual Studio refuses to refresh the data source and I can't find the new properties in my data source.

Tried restarting project, deleting and adding object as datasource again. Did not work.

Answer 1

Solution was to simply to rebuild the project.
