Add a Navigation Action to the 'Navigate to' Menu

What you should know beforehand:

Examples (?):

NavigateToCtorProvider.cs

If you want your navigation to appear in ReSharper's Navigate To menu (context navigation), you should create an action that implements the INavigateFromHereProvider interface.

For example, let's create a context-dependent navigation that navigates to a class constructor. The initial caret position can be anywhere inside that class.

[ContextNavigationProvider]
public class NavigateToCtorProvider : INavigateFromHereProvider
{
    public IEnumerable<ContextNavigation> CreateWorkflow(IDataContext dataContext)
    {
        var node = dataContext.GetSelectedTreeNode<ITreeNode>();
        var typeDeclaration = node?.GetParentOfType<IClassDeclaration>();            
        var constructor = typeDeclaration?.ConstructorDeclarations.FirstNotNull();
 
        if (constructor != null)
        {
            yield return new ContextNavigation("Constructor", null, NavigationActionGroup.Other, () =>
            {
                constructor.NavigateToTreeNode(true);
            });
        }                       
    }
}

Notes

The class must implement the INavigateFromHereProvider interface and be marked with the ContextNavigationProvider attribute.
GetSelectedTreeNode<ITreeNode>() method of IDataContext return the tree node under the current caret position.
We use the GetParentOfType method from Use Manual Navigation to obtain the IClassDeclaration node.
The IClassDeclaration class provides the ConstructorDeclarations property that returns an enumerable with class constructors.
A created instance of the ContextNavigation class describes the navigation feature:
- "Constructor": the name of the item that appears in the Navigate to context menu.
- null: action ID.
- NavigationGroup.Other: defines the location in the Navigate to menu where the action should be placed.
- The last one argument is the action that is run once the Constructor item is selected in the Navigate to menu.
Note that ReSharper automatically decides whether to display the item in the menu or not.
