Install and inspect the .NET SDK, create and run a project, understand top-level statements and namespaces, and publish a Release build.

Model data with properties, constructors, interfaces, records, and composition, and understand equality and immutability.

Choose collections, query them with LINQ, and write non-blocking async code with cancellation instead of blocking on Task.Result.

Build a layered console expense tracker with records, LINQ reports, JSON persistence, async file I/O, validation, and tests.
