Here's a simple VS.NET Tip:
When you double-click on a form in solution explorer, VS.NET will open up the form designer. You spend some time designing the look of your form and eventually, you're in the code -- full time. But every time you double-click on the form, the form designer comes back up. Wouldn't it nice be to double-click and jump right into code?
Right-click on a form file in solution explorer and select "Open With...":
In the dialog that pops up, select the "CSharp Editor" (or whatever language you use) and click the "Set As Default" button:
Now you're just a double-click away from the code!
