This document provides an overview of the ReSharper SDK, which allows developers to create plugins for the ReSharper productivity tool for Visual Studio. It discusses features supported by ReSharper, the components included in the SDK such as project templates and binaries, and how the SDK can be used to develop plugins that integrate with ReSharper's Program Structure Interface to add new code analysis checks, refactorings, and other functionality. Example plugin code and a testing structure using conventions are also demonstrated.

9. Win-Win Situation

10. `Problem`
public void Foo()
{
// correct use of string.Format()
string str = string.Format(“Name: {0}”, name);
// unnecessary method call
string str = string.Format(“string without markers”);
// much better
string str = “string without markers”;
}
// even more better? actually it’s not
const string str = “string without markers”;
