Executing refactorings from a plug in code

Hi,

Just a very basic question, but cannot find a sample code for doing it: How can I execute a refactoring programmatically

I'm trying to rename with the following code. I want to replace the last line with a proper "Rename" refactoring .

[ContextAction(Group="VB", Name="MyAction")]

protected override Action<JetBrains.TextControl.ITextControl> ExecuteTransaction(JetBrains.ProjectModel.ISolution solution, JetBrains.Application.Progress.IProgressIndicator progress)

{

var method = _provider.GetSelectedElement<IMethodDeclaration>(false, true);

if (method != null) method.SetName("HelloWorld");

...

Thanks,

Sebastian
