This is a tool that shows the size of things (types, methods, static arrays, etc.) in a .NET assembly.
You can find a binary download under the Releases page.
On launch it shows a file selection dialog with which you can load any kind of .NET assembly (exe or dll).
Once loaded, it shows the things stored in the assembly in a tree view with the accumulated size on the right.
The usual structure is:
[assembly name] → [namespace] → [class] → [thing]
If launched via command line, it takes a path to an exe or dll file as the first argument.
The tool is not fully accurate as it uses the simple approach of inspection via .NET's built-in reflection.
While the size of actual byte instructions of functions is correct, overhead from types, fields, etc. is estimated.
A more accurate method would be to use a custom .NET metadata reader library like dnlib that could read byte-accurate information.
