Renaming a class object and a windows service object in VS 2010

Folks, my project scope / requirements were modified in the middle of development (never happened before)...

so my issue right now is that I need to rename my class object which is currently named EmployerWorkflowService to EmployerWorkflow

because a new windows service object will be created that will be named "EmployerWorkflowService"

I am using VS 2010, C#. There is only one solution file that contains both these projects.

Any suggestions on how to rename the class object as painlessly as possible and have the whole solutio开发者_开发知识库n file compile?

Right-click on class name in Visual Studio, select Refactor > Rename... and Visual Studio will update all references for you.
As a shortcut, you can press F2 when caret is on the class name, or use a smart tag that appears when you edit the name manually.
