Dynamic Data is a .NET library that brings Reactive Extensions (Rx) to in-memory collections. It provides SourceCache and SourceList data sources plus 60+ operators to declaratively filter, sort, group, join, transform, and bind dynamically updating collections.

Use cases

• keep a UI collection in sync with asynchronous updates
• filter and sort a live data source reactively
• group and join multiple observable collections
• bind observable collections to WPF or Avalonia MVVM views
• manage collection disposal and expiration reactively
• paginate or virtualize large reactive data sets

When to choose

• you build .NET MVVM apps with collections that change over time
• you already use Rx.NET and need collection management operators
• you want declarative pipelines instead of manual collection mutation code

When to avoid

• your collections are static and rarely change
• you work outside the .NET ecosystem
• you prefer simple imperative collection code without Rx complexity
