Go to definition on concrete type

Question

Is there an extension for visual studio that would allow to do Go to Definition from a method and have it navigate straight to the concrete implementation instead of interface? Most of my code is inteface based and right if i do Go to definition it goes straight to the interface which makes sense, be nice to have Go to Concrete implementation..Thankx

Answer 1

If you using resharper it offers go to implementation and if there are different implementations you can choose among different implementation.

Also in the visual studio you can use find all references, method icon is different from calls, Also you can navigate on them by F8.

And in the visual studio 2010 or later you can use "ctrl"+"," and write the name in the window that appears in this action, then select among shown candidates, in this case you allowed to write abbreviations, ....

Answer 2

This isn't possible, as the IDE doesn't know which implementation is used when you rightclick a method. Given this example, which method should the IDE navigate to:

public interface IGreeterService
{
  string Greet(string person);
}

public class EnglishGreeterService : IGreeterService
{
  string Greet(string person)
  {
    return "Hello, " + person + ".";
  }
}

public class GermanGreeterService : IGreeterService
{
  string Greet(string person)
  {
    return "Guten Tag, " + person + ".";
  }
}

public class PersonGreeter
{
  private readonly IGreeterService _Service;

  public PersonGreeter(IGreeterService service)
  {
    _Service = service;
  }

  public void SayHallo()
  {
    _Service.Greet("user282807");
  }
}

It is impossible to know which implementation is used in the class PersonGreeter; that's the point of interfaces, so you don't rely on a specific implementation. Of course, this can be tiresome while developing.

Answer 3

If you are using CodeRush then you can use Ctrl + Alt + N to bring up the navigation choices and go to Implementations

Answer 4

Hi i dont know can it be usefull or not but i use Visual Assist "Find all references"

Answer 5

Visual Assist includes interface implementations in its alt+g (go to) command as of Build 1836 (November 10, 2010).
