Most used types (Rank)

Code Query Statistics

Lists the 100 application types with the highest TypeRank, computed by the Google PageRank algorithm on the types dependency graph: types used by many types themselves having many users. Metric: https://www.ndepend.com/docs/code-metrics#TypeRank

Any change to a much-used type impacts most clients: painful. So high-TypeRank types should preferably be interfaces, less subject to change, and shielding clients from implementation details — in essence the Liskov Substitution Principle: http://en.wikipedia.org/wiki/Liskov_substitution_principle

This code query is written in CQLinq, C# LINQ over the NDepend code model. It ships with every new NDepend project: you can read it, adapt it, or use it as a starting point for your own custom rules.
