## What it is
A .NET Core / .NET Standard port of Microsoft's Dynamic LINQ library that lets developers write string-based LINQ queries against IQueryable sources. It supports dynamic Where, OrderBy, Select, GroupBy, lambda parsing (ParseLambda), and dynamic class creation, integrating tightly with Entity Framework Core.

## Use cases
- build dynamic where clauses from user input at runtime
- sort and filter grids with string-based order by expressions
- parse strings into lambda expression trees
- dynamically project and shape query results with select
- create dynamic group by queries in entity framework
- generate dynamic classes at runtime

## When to choose
- you need runtime-defined LINQ queries driven by end-user UI input
- you use Entity Framework Core and want string-based filtering or sorting
- you need to parse strings into expression trees or lambdas
- you want a mature, actively maintained dynamic query library for .NET

## When to avoid
- your queries are fully known at compile time and type-safe lambdas suffice
- you need to evaluate arbitrary C# code at runtime (use a full expression evaluator)
- you cannot accept the security restrictions on calling methods in dynamic expressions

## Facets
- artifact type: library
- maturity: active
- function: orm, parser, serialization
- domain: developer-tools, databases, apis
- platform: dotnet, cross-platform
- tags: linq, dynamic-queries, entity-framework-core, expression-trees, string-based-querying, csharp
