C# Recipes vs P 4.0 SOLUTION

An everyday C# reference, from strings and collections to classes, LINQ and async work. Most examples have comments in the code and run right in the app. • 26 sections: basic types, arrays and collections, classes and structs, interfaces and generics, LINQ, functions and lambdas, async and threading, exception handling, regular expressions, files, serialization, design patterns. • Run in the app: the example actually runs and the output appears under the code. Needs an internet connection. • What changed in new versions: 11 sections from C# 2.0 to 12.0, with the old and the new code side by side. • Keyword and function reference: over 400 articles, open in full, with no daily limit. • SQL alongside: over 200 queries against a live practice database (JOIN, GROUP BY, subqueries, data types). • Edit examples and add your own; they stay in the app and are always at hand. • Search looks inside the code itself, not just the titles: remember a fragment and you will find the example. • Everything except running works offline. No account needed. WHAT THE FREE VERSION INCLUDES 12 runs and 12 edits a day; the counter resets every morning. The keyword reference is open without limits. Up to 5 examples of your own. The full version unlocks every example, lifts the daily limits and raises the run limit to 30 a day. One purchase, no subscription. Examples are drawn from professional sources and verified by running them. Built by a developer for developers. In active development since 2015.
