AutoMapper VS Hot Chocolate

AutoMapper

The 13.0 Upgrade Guide page was created back in April, but there is no sign of the release yet.

The most well-know is probably AutoMapper, but it's not universally liked.

AutoMapper - well for automapping

When working with AutoMapper, we often bump into runtime errors due to invalid mapping configuration, such as this one:

What problems will resolve automapper?

If you are a fan of data mappers, you might want to enhance the implementation with additional extension methods. Here is an example for AutoMapper.

I'm wondering myself. Most mappers like https://automapper.org/ will make a best effort mapper automatically via introspection. If this is just a DSL/annotation suite that requires explicit, complete mapping implementations then this strikes me as a re-implementation of parts of kotlin in kotlin.

There are some libraries which allows you to declare some class with more or less arbitrary methods which will be called by it at runtime. I believe many of them do that in optimal way, not just using usual reflection. One of the examples is HotChocolate library https://github.com/ChilliCream/hotchocolate . You declare class with arbitrary methods which contain arbitrary arguments. "Arbitrary" doesn mean arbitrary at all, but if parameter type is registered in DI or marked by specific attribute, it can be passed to the method.

At work we are considering using GraphQL to build our read-only data-APIs using .NET 6, EF Core and SQL Server. Looking at the ecosystem the most relevant plattforms seems to be graphql-dotnet and ChilliCream.

I'm starting a brand new project. Looks like if we want to do GraphQL in .NET, it's either graphql-dotnet or Hot Chocolate. Both look pretty good on paper.

If you know it better: Please try statically typed generated graphql queries in C# (like write the graphql queries, have a graphql schema, then get generated C# types which resemble the query, the only thing I've found that could do it was https://chillicream.com/docs/strawberryshake and there I quickly hit this bug with super simple queries containing unions: https://github.com/ChilliCream/hotchocolate/issues/4662

If you don't know Hot Chocolate framework, feel free to read about it on chillicream.com (official website) and feel free to join the great community (which is always willing to help) on slack

I love using Hot Chocolate in C# ❤

Hotchocolate GraphQL server. This is the most advanced server for a .Net environment. This article does not go into the basics and assumes some framework knowledge.

I think for the time being that's the case, yeah. I'm confirming with the great people over at https://github.com/ChilliCream/hotchocolate to see if we can somehow work around that.
