I am inspecting a large C# project. I tend to use `Shift+Ctrl+F` a lot to find in which files a specific function or field name occurs.

The problem is that `Shift+Ctrl+F` does not search inside .dll files that are included inside the project. Once you decompile a class from .dll file, you can search within with `Ctrl+F`, but I found no way to also search among other files.

How can I search all files (.dll or .cs) for a string? I am using Rider IDE, but can also revert to Visual Studio.
