Servicestack as SSRS datasource - reporting-services

Question

I am trying to use servicestack as a datasource for my SSRS report. Is this possible? Right now I have a simple operation that takes a date as a parameter, looks like this in C#
[DataContract]
[Route("/Reports/SummaryBySymbol/{SummaryDate}", Summary = "Summarizes trades by symbol for a specific date.")]
public class GetTradesGroupedBySymbol : IReturn<TradesGroupedBySymbolResponse>
{
[DataMember]
[ApiMember(Name = "Summary Date",
Description = "The date for which the trades will be summarized..",
DataType = "DateTime",
IsRequired = true)]
public DateTime SummaryDate { get; set; }
}
[DataContract]
public class TradesGroupedBySymbolResponse
{
[DataMember] public IList<SymbolSummary> Result { get; set; }
}
I am trying to create a dataset in SSRS using: http://machineName:port/soap11
as the datasource.
When the dataset asks for a query, I have no idea what to enter as text and the examples I can find always cause the interface to freeze when I hit the 'next' button (so I must assume I entered something incorrectly).
Here is what I tried to enter as the query:
<Query>
<Method Namespace="http://www.company.com/types" Name="GetTradesGroupedBySymbol" />
<SoapAction>
http://www.company.com/types/GetTradesGroupedBySymbol
</SoapAction>
<Parameters>
<Parameter Name="SummaryDate" Type="XML"/>
</Parameters>
<ElementPath IgnoreNamespaces="True">
GetTradesGroupedBySymbolResponse{}/Result{}/SymbolSummary
</ElementPath>
</Query>
Here is the wsdl for the service:

I would expect the query to ask me for a parameter before attempting to run the soapAction (or at least error out), but the interface just locks up and I have to kill Visual Studio. Any ideas out there as to what I am doing wrong?
EDIT 1
Modified the above query and wsdl to show latest attempts to get this to work. VS still freezes.

Answer 1

It appears that the problem was the long running webservice response causing a connection time out in the wizard and causing the entire VS2017 environment to freeze (not optimal behavior). Once I created a dummy version of the webservice that responds with the same DTO and couple of dummy rows but that returned in less than a second, everything worked. The report was generated and I could then go in to the dataset, change the timeout to be 2 minutes and then changed the query to point back to the real web method and it worked as expected.
As a follow up detail, if you are passing a date to ServiceStack, use the 'String' data type (not XML) and ensure that the date format is yyyy-mm-dd (months and days must be padded with zeros if they are single digit values).
