I have created a class MyDataSet that inherits from the DataSet class. In the constructor of MyDataSet I read a xml schema from a file which specifies all the tables and columns of my dataset. Then when I drop a DataSet from the Data Toolbox in Visual Studio it ask me if I want to create I typed or untyped dataset. I choose typed dataset, and the name XPDataSet.MyDataSet (where XPDataSet is the namespace of my project). Later, when writing code, the tables and columns in my instance of my dataset does not appear in the IntelliSense. How would I go about this? I mean, to get the tables and colums to appear in IntelliSense when the schema is specified on an external file...
