Bare minimum GraphQL project with dotnet 6 minimal API and HotChocolate

Steps

• Install latest version of HotChocolate.AspNetCore
• Add to container builder.Services.AddGraphQLServer().AddQueryType<Query>();
• Use app.UseEndpoints(endpoints => { endpoints.MapGraphQL(); }); after app.UseRouting();
• Run project and navigate to /graphql
• Javascript client should send post request wrapping payload with JSON.stringify

See Program.cs

using API.GraphQL;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddGraphQLServer().AddQueryType<Query>();

var app = builder.Build();

app.UseRouting();

app.UseEndpoints(endpoints =>
{
    endpoints.MapGraphQL();
});

app.Run();

Sample Javascript client request

$.ajax({url: "http://localhost:9000/graphql",
  contentType: "application/json",type:'POST',
  data: JSON.stringify({ query:`{
	 sayHello(name:"${name}")}`
  }),
  success: function(result) {
	 console.log(JSON.stringify(result))
	 $("#SayhelloDiv").html("<h1>"+result.data.sayHello +"</h1>");
  }
});
