title: String search in all .dll files in project
body: <p>I am inspecting a large C# project. I tend to use <code>Shift+Ctrl+F</code> a lot to find in which files a specific function or field name occurs.</p>
  
  <p>The problem is that <code>Shift+Ctrl+F</code> 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 <code>Ctrl+F</code>, but I found no way to also search among other files.</p>
  
  <p>How can I search all files (.dll or .cs) for a string? I am using Rider IDE, but can also revert to Visual Studio.</p>
