Introducing WhereDynamic
We've all been there: writing endless if statements to build conditional queries, or duplicating logic across multiple endpoints just to handle different filter combinations. It's messy, error-prone, and hard to maintain.
That's why I'm excited to announce WhereDynamic a powerful new feature that lets you build LINQ queries dynamically at runtime, without hardcoding filters or sacrificing type safety.
The Problem
When building APIs or data-driven applications with .NET and Entity Framework, we often need to apply filters based on user input. Traditional approaches lead to bloated code:
This doesn't scale well and becomes a maintenance nightmare.
The Solution
WhereDynamic allows you to construct flexible, runtime queries with a clean, fluent API:
Practical Use Cases
1 - Advanced Search Filters
2 - Multi-Tenant Data Filtering
3 - API Query Parameters
4 - Complex Nested Conditions
Key Benefits
- Cleaner Code – Eliminate repetitive conditional logic
- Type Safety – Compile-time checks with IntelliSense support
- Performance – Translates directly to optimized SQL queries
- Maintainability – Centralized filter logic, easier to test and extend
- Flexibility – Works seamlessly with existing Entity Framework code
Built For Modern .Net
WhereDynamic is built on .NET 8+, fully compatible with Entity Framework Core, and designed with performance and developer experience in mind. Whether you're building REST APIs, GraphQL endpoints, or complex reporting systems, it adapts to your needs.
