Non-blocking Schema Initialization for ASP.net core middleware

Is your feature request related to a problem? Please describe. I’m just started looking into this tool so perhaps I’m missing something, but it would be nice if there were the option to load the schema in a non-blocking when using the ASP.net core middleware.

Right now I’m having to do something like this to initialize the schema in Startup.cs:

public void ConfigureServices(IServiceCollection services) { ISchema schema = Schema.Create(File.ReadAllText(($"{env.ContentRootPath}/GraphQL/schema.graphql"))); services.AddGraphQL(schema); }

Describe the solution you’d like It would be nice if there were an alternative async lazy initialization. I imagine there could be performance downsides if requests come in before the application loads; however, this could be mitigated by using something like this (https://github.com/thomaslevesque/AspNetCore.AsyncInitialization) for those concerned about performance.

Describe alternatives you’ve considered

• Not using the middleware and implementing async schema loading/the endpoint
• Maybe this is possible and I’ve just overlooked something key

If you are on version 9 preview try the new schema builder:

SchemaBuilder.New()
    .AddDocumentFromString("type Query { ....")
    .BindResolver<MutationResolver>().To("Mutation")
    .BindResolver<QueryResolver>().To("Query")
    .Create();

This one is now implemented with the new configuration API on version 11.
