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
