I have:
private readonly ReportingService2010 _rs = new ReportingService2010();
Error:
The type or namespace name \'ReportingSer
Change this;
private readonly ReportingService2010 _rs = new ReportingService2010()
to
private readonly ReportingService2010SoapClient _rs = new ReportingService2010SoapClient()
You are attempting to create an instance to a class that does not exists and adding the reference creates a corresponding *Client class for you to instantiate.
