I assumed that because the 'Node class itself is constrained in the way shown in my code example ... implements IEquatable, and the 'TestClass is also constrained and implements IEquatable, that it was not necessary for me to also constrain the 'Gather method.

Working with local databases[^]

This connection string syntax is supported by the SqlClient and OleDb managed providers.

By default, the |DataDirectory| variable will be expanded as follow:

• For applications placed in a directory on the user machine, this will be the app's (.exe) folder;
• For apps running under ClickOnce, this will be a special data folder created by ClickOnce;
• For Web apps, this will be the App_Data folder;
