This is an implementation of Facebook's GraphQL in .NET.
Now the specification is being developed by the GraphQL Foundation.
This project uses a lexer/parser originally written by Marek Magdziak and released with a MIT license. Thank you Marek!
Provides the following packages:
Package | Downloads | NuGet Latest |
---|---|---|
GraphQL | ||
GraphQL.SystemTextJson | ||
GraphQL.NewtonsoftJson | ||
GraphQL.MemoryCache | ||
GraphQL.DataLoader | ||
GraphQL.MicrosoftDI |
You can get all preview versions from GitHub Packages. Note that GitHub requires authentication to consume the feed. See here.
Documentation
- http://graphql-dotnet.github.io - documentation site that is built from the docs folder in the
master
branch. - https://graphql.org/learn - learn about GraphQL, how it works, and how to use it.
Debugging
All packages generated from this repository come with embedded pdb and support Source Link. If you are having difficulty understanding how the code works or have encountered an error, then it is just enough to enable Source Link in your IDE settings. Then you can debug GraphQL.NET source code as if it were part of your project.
Installation
1. GraphQL.NET engine
This is the main package, the heart of the repository in which you can find all the necessary classes for GraphQL request processing.
> dotnet add package GraphQL
2. Serialization
For serialized results, you'll need an IGraphQLSerializer
implementation.
We provide several serializers (or you can bring your own).
> dotnet add package GraphQL.SystemTextJson
> dotnet add package GraphQL.NewtonsoftJson
Note: You can use
GraphQL.NewtonsoftJson
with .NET Core 3+, just be aware it lacks async writing capabilities so writing to an ASP.NET Core 3.0HttpResponse.Body
will require you to setAllowSynchronousIO
totrue
as per this announcement; which isn't recommended.
3. Document Caching
The recommended way to setup caching layer (for caching of parsed GraphQL documents) is to
inherit from IConfigureExecution
interface and register your class as its implementation.
We provide in-memory implementation on top of Microsoft.Extensions.Caching.Memory
package.
> dotnet add package GraphQL.MemoryCache
For more information see Document Caching.
4. DataLoader
DataLoader is a generic utility to be used as part of your application's data fetching layer to provide a simplified and consistent API over various remote data sources such as databases or web services via batching and caching.
> dotnet add package GraphQL.DataLoader
For more information see DataLoader.
Note: Prior to version 4, the contents of this package was part of the main GraphQL.NET package.
5. Subscriptions
DocumentExecuter
can handle subscriptions as well as queries and mutations.
For more information see Subscriptions.
6. Advanced Dependency Injection
Also we provide some extra classes for advanced dependency injection usage on top of
Microsoft.Extensions.DependencyInjection.Abstractions
package.
> dotnet add package GraphQL.MicrosoftDI
For more information see Thread safety with scoped services.
Examples
https://github.com/graphql-dotnet/examples
You can also try an example of GraphQL demo server inside this repo - GraphQL.Harness. It supports the popular IDEs for managing GraphQL requests and exploring GraphQL schema:
Ahead-of-time compilation
GraphQL.NET supports ahead-of-time (AOT) compilation for execution of code-first schemas with .NET 7. This allows
for use within iOS and Android apps, as well as other environments where such features as JIT compilation or
dynamic code generation are not available. It may be necessary to explicitly instruct the AOT compiler
to include the .NET types necessary for your schema to operate correctly. Of particular note, your query,
mutation and subscription types' constructors may be trimmed; register them in your DI engine to prevent this.
Also, Field(x => x.MyField)
for enumeration values will require manually adding a mapping reference via
RegisterTypeMapping<MyEnum, EnumerationGraphType<MyEnum>>()
. Please see the GraphQL.AotCompilationSample
for a simple
demonstration of AOT compilation. Schema-first and type-first schemas have additional limtations and configuration requirements.
AOT compilation has not been tested with frameworks other than .NET 7 on Windows and Linux (e.g. Xamarin).

Upgrade Guides
You can see the changes in public APIs using fuget.org.
Basic Usage
Define your schema with a top level query object then execute that query.
Fully-featured examples can be found here.
Hello World
using System;
using System.Threading.Tasks;
using GraphQL;
using GraphQL.Types;
using GraphQL.SystemTextJson; // First add PackageReference to GraphQL.SystemTextJson
var schema = Schema.For(@"
type Query {
hello: String
}
");
var root = new { Hello = "Hello World!" };
var json = await schema.ExecuteAsync(_ =>
{
_.Query = "{ hello }";
_.Root = root;
});
Console.WriteLine(json);
Schema First Approach
This example uses the GraphQL schema language. See the documentation for more examples and information.
public class Droid
{
public string Id { get; set; }
public string Name { get; set; }
}
public class Query
{
[GraphQLMetadata("droid")]
public Droid GetDroid()
{
return new Droid { Id = "123", Name = "R2-D2" };
}
}
var schema = Schema.For(@"
type Droid {
id: ID
name: String
}
type Query {
droid: Droid
}
", _ => {
_.Types.Include<Query>();
});
var json = await schema.ExecuteAsync(_ =>
{
_.Query = "{ droid { id name } }";
});
Parameters
public class Droid
{
public string Id { get; set; }
public string Name { get; set; }
}
public class Query
{
private List<Droid> _droids = new List<Droid>
{
new Droid { Id = "123", Name = "R2-D2" }
};
[GraphQLMetadata("droid")]
public Droid GetDroid(string id)
{
return _droids.FirstOrDefault(x => x.Id == id);
}
}
var schema = Schema.For(@"
type Droid {
id: ID
name: String
}
type Query {
droid(id: ID): Droid
}
", _ => {
_.Types.Include<Query>();
});
var json = await schema.ExecuteAsync(_ =>
{
_.Query = $"{{ droid(id: \"123\") {{ id name }} }}";
});
Roadmap
