How do I pass two parameters to GraphQLHttpClient in c#?

Question

I am having a problem similar to this . I have updated my GraphQLHttpClient and now I need to supply an extra parameter, solution give is:

GraphQLHttpClient gql = new GraphQLHttpClient(o => {
o.EndPoint = _config["API:Endpoint"];
o.JsonSerializer = new NewtonsoftJsonSerializer();
});

but this tells me: Error CS1729 'GraphQLHttpClient' does not contain a constructor that takes 1 arguments I have also tried:

using Newtonsoft.Json
GraphQLHttpClient gql = new GraphQLHttpClient(_options.Url, new Newtonsoft.Json.JsonSerializer());

which gives Error CS1503 Argument 2: cannot convert from 'Newtonsoft.Json.JsonSerializer' to 'GraphQL.Client.Abstractions.Websocket.IGraphQLWebsocketJsonSerializer'

I know very little c# so I'd be grateful for any pointers.

Answer 1

Your first solution correctly tries to use NewtonsoftJsonSerializer which is an implementation of IGraphQLWebsocketJsonSerializer to use Newtonsoft.

Your second correctly uses a constructor which takes it, but you have changed it to be Newtonsoft.Json.JsonSerializer which is not an implementation of IGraphQLWebsocketJsonSerializer .

What you want is the second one, but with the right type of IGraphQLWebsocketJsonSerializer :

GraphQLHttpClient gql = new GraphQLHttpClient(_options.Url, new NewtonsoftJsonSerializer());
