Giving Clarity to LINQ Queries by Extending Expressions
summary
Deep dive into .NET Expression trees shows how expression visitors rewrite and compile lambdas, produces a tiny predicate extensions library that composes AND/OR predicates, and demonstrates dynamic query generation for arrays of authors. Examples use LINQ and Entity Framework style expression translation, include unit tests that stay green, and culminate in a Telluric UI demo that serializes expression objects for ad hoc querying. Focus is on concrete rewrites, runtime compilation, and a working small library.
