This is an extension to Visual Studio for easy visual analysis of the "Could not load file or assembly or one of its dependencies" problem and issues related to referenced assemblies. The tool allows selecting an .Net assembly (.ddl or .exe file) and get a graph of all referenced assemblies with hightlighted conflicting references.
After installation it is available in the main menu: Tools -> Analyze Assembly Dependencies.

Note: the extension relies on the built-in DGML editor. In case you see the raw XML instead of the diagram run Visual Studio Installer, then: Modify -> Individual Components -> Code Tools -> Install DGML editor.
