graphql-dotnet/server always consuming memory for IntrospectionQuery

I am using graphql-dotnet/server to host my services. I have made my schema class singleton. For every IntrospectionQuery it is increasing the memory consumption by the server. So more more and request comes in memory goes high. Is there any solution to minimize this issue. Expecting your help. I am using the following code to initialize my graphQL service and my schema class is a singleton

services.AddGraphQL(_ =>
                {
                    _.EnableMetrics = true;
                    _.ExposeExceptions = true;
                });
services.AddSingleton<PdsGraphQlSchema>();

and inside Configure I have used following

app.UseGraphQL<PdsGraphQlSchema>();
app.UseGraphQLPlayground(new GraphQLPlaygroundOptions
{
	Path = "/ui/playground"
});

Expecting your help.

I tried with 3.5.0-alpha0046. Ran the ui/playground for 20 mins continuously polling on my graph with 30+ custom types.

Memory stayed constant at 443 MB.

Closing this as solved.
