Navigation within Resx Files
JetBrains Rider will help you navigate and search for resources within these files. The Go to File Member command works perfectly in .resx files and allows you to jump to any resource with a few keystrokes.
To navigate resources in the editor
Open a .resx file in the editor.
You will see the list of resource entries in a popup. You can start typing to narrow down the list.
When you see the desired string in the list, select it and press Enter or click on it.
JetBrains Rider's Structure window can display the structure of resource files. It lists all resource entries in a resource file, visualizing resource IDs, resource text in the current culture, and resource comments (if any).
