 Support for doing multiple things at the same time is fundamental to practically all workloads. That could be client applications doing background processing while keeping the UI responsive, services handling many thousands of simultaneous requests, devices responding to a multitude of simultaneous stimuli, or high-powered machines parallelizing the processing of compute-intensive operations. Asynchronous programming support is a first-class feature of the C# programming language, which provides the `async` and `await` keywords that make it easy to write and compose asynchronous operations while still enjoying the full benefits of all the control flow constructs the language has to offer.
 
-The [type system](../standard/base-types/common-type-system.md) offers significant breadth, catering somewhat equally to safety, descriptiveness, dynamism, and native interop. First and foremost, the type system enables an object-oriented programming model. It includes types, (single base class) inheritance, interfaces (including default method implementations), and virtual method dispatch to provide a sensible behavior for all the type layering that object orientation allows. [Generic types](../standard/generics.md) are a pervasive feature that let you specialize classes to one or more types.

-The .NET runtime provides automatic memory management via a garbage collector. For any language, its memory management model is likely its most defining characteristic. This is true for .NET languages. .NET has a self-tuning, tracing GC. It aims to deliver "hands off" operation in the general case while offering configuration options for more extreme workloads. The current GC is the result of many years of investment and learnings from a multitude of workloads.

 Value types and stack-allocated memory blocks offer more direct, low-level control over data and native platform interop, in contrast to .NET's GC-managed types. Most of the primitive types in .NET, like integer types, are value types, and users can define their own types with similar semantics. Value types are fully supported through .NET's generics system, meaning that generic types like `List<T>` can provide flat, no-overhead memory representations of value type collections.
