Find referenced code

This command helps you find any outgoing references within a certain scope, which can be as narrow as a function or as large as a project.

This command comes in handy when you are going to move a class or a method to another place. You will be able to use the list of outgoing references to estimate additional changes that the move will require.

Consider the ExternalSymbols class below. If you run the command on the constructor, the search result will be a single usage of the method Divide, because it is defined outside the constructor. If you run the command on the class, the search result will be the usage of System.ArgumentOutOfRangeException, because the rest is defined inside the class.

class ExternalSymbols // Symbols external to the class: System.ArgumentOutOfRangeException
{
    ExternalSymbols() // Symbols external to the constructor: MyProject.ExternalSymbols.Divide
    {
        var x = Divide(10,2);
    }

    private int Divide(int numerator, int denominator)
    {
        if (denominator != 0)
            return numerator/denominator;
        throw new ArgumentOutOfRangeException(nameof(denominator));
    }
}

Find usages of the symbols defined outside the current scope

Place the caret at a function or a class.
Press Control+Shift+G or choose Navigate | Navigate To… from the main menu , and then select Referenced Code in the Navigate To menu.
The search results appear in the Find window, where you can further analyze the results.
