No more red dot on scroll bar in Visual Studio 2012 - visual-studio-2010

Question

At Visual Studio 2010, there will be a red dot(s) on scroll bar indicated where your code has errors. Also a other color dots for other message etc.
But after installed Visual Studio 2012, I cannot see this feature anywhere, tried toolbar-options, nowhere to found.
Am I miss something? Or Microsoft just removed this feature.
{EDIT}
Sample of Visual Studio 2010
And Visual Studio 2012, where these nice little dot candy go?

Answer 1

The dots you see on the scrollbar are definitely a feature of the "Productivity Power Tools" Extensions "Enhanced Scrollbar".

There are 3 Modes to enhance the Scrollbar, your Screenshot displays the first (default) one.
Unfortunately, there seems to be no equivalent for VS2012. Or does anyone know of an extension that improves the scrollbar like that?

Answer 2

Is it possible you were using the jetbrains resharper tool? That provides the feature you describe, but I don't recall ever seeing it in visual studio

Answer 3

Have you got code errors? :P
Check the editor settings out, I am pretty sure it is there it might just be off by default.
As you add code and build your solution, you may see different-colored wavy underlines (known as squiggles) appearing in your code. These marks notify you of problems Visual Studio has detected in your code. For example, red squiggles denote syntax errors, blue squiggles denote compiler errors, green squiggles denote warnings, and purple squiggles denote other types of error. For example, they are used for "rude" edits in Visual Basic, which are changes that are made during Edit and Continue and that will result in compiler errors.
You can see the default color for each error and warning squiggle in the Tools/Options/Environment/Fonts and Colors dialog box. Look for Syntax Error, Compiler Error, Warning, and Other Error.
