Let’s say you create a new class file called Class1.  If you try to rename "Class1" in the solution explorer, we’ll prompt you whether you want to rename all references to this code element in your project. 

But I’m more of a IDE Tips and Tricks know-it-all, so the real "did you know" here is … did you know, you can disable this prompt and just have VS automatically do the rename for you?

Go to Tools – Options – Projects and Solutions – General and uncheck the Prompt for symbolic renaming when renaming files.
