Delegates, plugins, JWT, and EF Core
A varied .NET roundup covering delegates, plugin loading, JWT handling, URI templates, testing tradeoffs, and EF Core internals.
Jasen's top three picks
- 1 Introduction to Delegates in C#
c-sharpcorner.com
A solid refresher on delegates, including multicast behavior and the built-in Func, Action, and Predicate types.
- 2 Real Plugin Systems in .NET: AssemblyLoadContext, Unloadability, and Reflection‑Free Discovery
jordansrowles.medium.com
A practical look at plugin architectures in .NET, especially unloadability and avoiding reflection-heavy discovery pitfalls.
- 3 Create and Read JWT Tokens in C# .NET
codeexact.medium.com
A straightforward JWT guide focused on creating and reading tokens, with enough basics to get moving quickly.
Editor's note
I put together a mixed issue this time, with fundamentals and deeper runtime work side by side. The plugin-system piece stands out for its practical take on unloadability, and the EF Core model article is a useful reality check on caching and DbContext behavior. The delegates and pattern-matching refreshers round it out for developers who want a cleaner mental model of core language features.
