C#: From Beginner to Advanced

Async is the concept that most often gets learned twice in C#, and badly both times - once as syntax that makes the compiler stop complaining, and later as a performance model when something falls over under load. Covering the whole distance in one path lets it be introduced once, properly, as what it actually is: a transformation the compiler performs on your method.

Sample curriculum

An example outline for going from beginner to advanced in C#. Your generated course adapts this to your experience, target level and available study time.

  1. Types, Collections and Generics

    Value against reference types, the collection types by access pattern, generic constraints, and the equality and hashing contract that underpins dictionaries and sets.

  2. LINQ and Deferred Execution

    Query composition, deferred evaluation and the double-enumeration bug, grouping and projection, and the point at which a loop reads better than a chain.

  3. Interfaces, Injection and Structure

    Designing to interfaces, dependency injection as plumbing rather than magic, and organising a solution so the parts can be tested in isolation.

  4. Asynchrony From the Ground Up

    await as a state machine transformation, Task composition, cancellation, and the blocking calls that cause thread-pool starvation under real traffic.

  5. Memory and Allocation

    Where garbage comes from, boxing and closures, Span for buffer work, and profiling allocations rather than assuming which line is expensive.

  6. Testing, Benchmarking and Shipping

    xUnit with mocked dependencies, BenchmarkDotNet for claims you want to defend, NuGet packaging, and a deployment that runs on Linux.

C# beginner-to-advanced questions

Is one continuous C# path better than two separate courses?

For C# it usually is, because async sits awkwardly across the boundary. Beginner material introduces the keywords and advanced material assumes the execution model, leaving the part in between - what await actually does - covered by neither.

How long does beginner to advanced realistically take?

Around eighteen weeks at eight hours a week. The memory and profiling material in the second half needs a project large enough to have a hot path, so it moves more slowly than the syntax does.

What C# interview questions does this prepare me for?

The recurring ones across levels: value against reference types, deferred execution in LINQ, what await does to a method, IDisposable and using, and where allocations come from in a hot path.
