Introduction

EntityGraphQL is a .NET library that allows you to easily build a GraphQL API on top of your data model with the extensibility to easily bring multiple data sources together in the single GraphQL schema.

EntityGraphQL builds a GraphQL schema that maps to .NET objects. It provides the functionality to parse a GraphQL query document and execute that against your mapped objects. These objects can be an Entity Framework DbContext or any other .NET object, it doesn't matter.

A core feature of EntityGraphQL with Entity Framework (although EF is not a requirement) is that it builds selections of only the fields requested in the GraphQL query which means Entity Framework is not returning all columns from a table. This is done with the LINQ projection operator Select() hence it works across any object tree.

EntityGraphQL.AspNet will get you easily set up with ASP.NET. However the core EntityGraphQL package has no ASP.NET dependency.
