Question 1

How to set up EntityGraphQL with ASP.NET Core?

Accepted Answer

Install the EntityGraphQL.AspNet package, add services with AddGraphQLSchema, and use MapGraphQL in your app builder to set up a POST endpoint at /graphql, as detailed in the quick start guide.

Question 2

EntityGraphQL vs Hot Chocolate: which is better for .NET?

Accepted Answer

EntityGraphQL excels at efficient LINQ-based queries on existing .NET models, while Hot Chocolate offers more features like subscriptions. Choose based on performance needs versus advanced GraphQL capabilities.

Question 3

Does EntityGraphQL support real-time subscriptions?

Accepted Answer

No, EntityGraphQL primarily focuses on queries and mutations without built-in subscription support. For real-time updates, you may need custom implementations or consider other libraries.

Question 4

How to use EntityGraphQL with non-Entity Framework data sources?

Accepted Answer

It works with any .NET object via IQueryable or IEnumerable. Use SchemaBuilder to create a schema from plain objects, then compile queries to LINQ expressions, as shown in the EQL examples.

Question 5

How to implement authorization in EntityGraphQL schemas?

Accepted Answer

Authorization can be applied at the ASP.NET route level or within the schema using attributes or custom middleware, with documentation covering claims-based security for specific parts of the schema.

Question 6

What are the performance benefits over REST APIs?

Accepted Answer

EntityGraphQL reduces over-fetching by selecting only requested fields through LINQ projections, leading to optimized database queries and smaller payloads for complex data graphs.
