yeah, it looks like you are almost there.

see where in your screenshot it says "immediate window" at the bottom?

click on the tab next to that, the one that says "class details" that is the menu I posted my screenshot of.

From there you can easily add methods, properties, fields, and events, easily pick their datatypes (it even support intellisense), their access modifier (public, private, etc.) and even enter summary or choose to hide them.

There are other options to the left of the grid (like making constructors, constants, etc) so play around a little to figure out all the features and capabilities.

After you are done using this "wizard" if you go to your class code, you will see the code has auto generated for you based on what you did in the "wizard"
