All you need is stone and bare knuckle then you can do it like a caveman.

Remove unused namespaces (for each class)
Run Debug build
Copy your executable and remaining namespace references to new location
Run the executable
Missing Reference DLL error will occur
Copy required DLL from Debug folder
Repeat 4-6
Gu Gu Ga Ga?
Throw your stone

You can also rely on your build tools to let you know which reference is still required. It's the era of VS 2017, caveman still survived.

The Resharper extension will do this for you     This extension supports Visual Studio 2005 through 2017   While the compiler won t include unused assemblies  extraneous using statements and references slows down Visual Studio and Intellisense  since there s more code the tools have to consider

In a Visual Basic project there is support to remove  Unused References   Project-- References-- Unused References   In C  there isn  t such a function   The only way to do it in a C  project  without other tools  is to remove possible unused assemblies  compile the project and verify if any errors occur during compilation  If none errors occur you have removed a unused assembly   See my post    If you want to know which project  assembly  depends on other assemblies you can use NDepend

With Visual Studio versions 2017 and 2015  you can do this with the Code Map feature  but this feature is only available in the Enterprise Edition  not the Community or Professional versions   Right-click on the project node in the solution explorer and select  Show on Code Map   This will display your  dll as a single node in a blank graph  Right-click on that node in the Code Map and select  Show Assemblies This References   This will add an additional node called  Externals  which can be expanded to show only the assemblies that are actually referenced
