Get strong typed object from GraphQLHttpClient GraphQLResponse

Hello.

I am using GraphQLHttpClient library (https://github.com/graphql-dotnet/graphql-client.git) for query from one net.core servise to other. Other service use GraphQLServer library (https://github.com/graphql-dotnet/server).

Example types and queries is:

```c#
public abstract class CodeBase
{
//[Key]
[Column(Order = 1)]
public int TypeObjectId { get; set; }

//[Key]
[Column(Order = 2)]
public int ValueObjectId { get; set; }

[MaxLength(100)]
public string ValueName { get; set; }
}

[Table("CodeActivity")]
public partial class CodeActivity : CodeBase
{
//[Key]
[Column(Order = 0)]
public int ActivityObjectId { get; set; }

[ForeignKey("ActivityObjectId")]
[Required]
public virtual Activity Activity { get; set; }

[ForeignKey("ValueObjectId")]
[Required]
public virtual ActivityCode ActivityCode { get; set; }

[ForeignKey("TypeObjectId")]
[Required]
public virtual ActivityCodeType ActivityCodeType { get; set; }

[NotMapped]
public bool IsNew { get; set; }
}

public class CodeActivityGraphType : ObjectGraphType
{
public CodeActivityGraphType()
{
Name = "CodeActivity";
Field(x => x.TypeObjectId);
Field(x => x.ValueObjectId);
Field(x => x.ValueName, nullable: true);

Field(f => f.ActivityObjectId);
Field(f => f.Activity, false, typeof(ActivityGraphType));//.Resolve(ResolveFrom);
Field(f => f.ActivityCode, false, typeof(ActivityCodeGraphType));//.Resolve(ResolveFrom);
Field(f => f.ActivityCodeType, false, typeof(ActivityCodeTypeGraphType));//.Resolve(ResolveFrom);

Field(f => f.IsNew);
}

private Activity ResolveFrom(IResolveFieldContext context)
{
var activity = context.Source;
return activity;
}
}

public class DataSchemaQuery : ObjectGraphType
{
public DataSchemaQuery(IServiceProvider serviceProvider)
{
try
{
Field>("codeActivityList", "Returns a list of CodeActivity",
new QueryArguments(
new QueryArgument {Name = "take"},
new QueryArgument {Name = "skip"}
),

context =>
{
using var scope = serviceProvider.CreateScope();
var repository = scope.ServiceProvider.GetRequiredService>();

return repository.Find(null, context.Arguments["take"].GetPropertyValue(),
context.Arguments["skip"]?.GetPropertyValue() ?? 0).AsNoTracking().ToList();
});

Field("codeActivity", "Returns a Single CodeActivity",
new QueryArguments(
new QueryArgument>
{
Name = "activityObjectId",
Description = "Activity Id"
},
new QueryArgument>
{
Name = "typeObjectId",
Description = "Activity Id"
}),

context =>
{
using var scope = serviceProvider.CreateScope();
var repository = scope.ServiceProvider.GetRequiredService>();

return repository.Find(ca =>
ca.ActivityObjectId == context.Arguments["activityObjectId"].GetPropertyValue()
&& ca.TypeObjectId == context.Arguments["typeObjectId"].GetPropertyValue())
.FirstOrDefault();
});

}
catch (Exception e)
{
Console.WriteLine(e);
throw;
}
}
}
}
```

On client service code next:

```c#
var dataServiceUrl = "http://localhost:5002/graphql";
using var graphQLClient = new GraphQLHttpClient(dataServiceUrl, new SystemTextJsonSerializer());
var codeActivities = new GraphQLRequest
{
Query = @"
query ($activityObjectId: Int!, $typeObjectId: Int!) {
codeActivity(activityObjectId: $activityObjectId, typeObjectId: $typeObjectId) {
activityObjectId
typeObjectId
valueObjectId
valueName
}
}",
Variables = new
{
activityObjectId = 45685563,
typeObjectId = 97842
}
};

var graphQLResponse = await graphQLClient.SendQueryAsync(codeActivities);
```
in in graphQLResponse.Data i get new CodeActivity entity with empty fileds and properties. How i can get strong type entity CodeActivity with data wich returned server side?

Server side return next:

'
{
"Data": {
"codeActivity": {
"activityObjectId": 45685563,
"typeObjectId": 97842,
"valueObjectId": 1292036,
"valueName": "3 (\u0425\u0413\u041E)"
}
},
"Errors": null,
"Extensions": {
"tracing": {
"version": 1,
"startTime": "2021-03-10T06:33:36.742064Z",
"endTime": "2021-03-10T06:33:39.652064Z",
"duration": 2909844400,
"parsing": {...},
"validation": { ...},
"execution": {
"resolvers": [ {...} ]
}
}
}
}
'

Other question.

If i want get list of CodeActivity i wrote next code:
```c#
var dataServiceUrl = "http://localhost:5002/graphql";
using var graphQLClient = new GraphQLHttpClient(dataServiceUrl, new SystemTextJsonSerializer());

var codeActivities = new GraphQLRequest
{
Query = @"
query ($take: Int, $skip: Int) {
codeActivityList(take: $take, skip: $skip) {
activityObjectId
typeObjectId
valueObjectId
valueName
}
}",
Variables = new
{
take = 100, //take = null,
skip = 0
}
};

var graphQLResponse = await graphQLClient.SendQueryAsync>(codeActivities);
```
I get error :

if i replace var graphQLResponse = await graphQLClient.SendQueryAsync>(codeActivities) on
```c#
var graphQLResponse = await graphQLClient.SendQueryAsync>(codeActivities);
```

get error

what's wrong in queries? How i can get List<> of strong type entity CodeActivity?
