"Sync Block Edit" a Visual Studio 2010/2012 extension to sync multiple duplicate text blocks

Sergey Vlasov Studio - Sync Block Edit

The free Sync Block Edit extension lets you easily update duplicate blocks of text in multiple files from Visual Studio 2012/2010. It performs multiline search and replace in Visual Studio with you only pointing what changes to propagate.

It is undesirable, but often necessary to have duplicate blocks of text in multiple files. For example, Google Analytics tracking code in html files or copyright notices in code files. When you need to update this text, sometime you can do it with a simple search and replace.

Sync Block Edit hides all the complexity of writing multiline find and replace patterns from you.

If you do have to do it, then this extension will at least make it a little easier to keep from tearing out all your hair...
