Large datasets published with OData WCF Data Services and Excel PowerPivot

I want to publish an SQL Server database, for testing purposes AdventureWorksDW, 开发者_如何学JAVAthe data warehouse sample database that provides Microsoft. I created a new "WCF Data Service" project in VS and created an Entity Framework Model to pass it into the generic parameter of DataService base class. I included in the model some dimensions and the facts table FactInternetSales. It seem that FactInternetSales table contains too much data (60398 records) to be accessed through OData by default. When I try to iterate the FactInternetSales entity set from a console app, I get an System.Net.WebException with the message:

The underlying connection was closed: The connection was closed unexpectedly.

If I limit the numbers of rows to iterate, said 1000, I have not problem.

On the other hand, when I try to load the data from FactInternetSales into PowerPivot using this OData Service, I get this error message:

Unable to obtain schema for data feed 'FactInternetSales'. Please make sure this feed exists.

In the InitializeService method of the OData Service I have set config.SetEntitySetPageSize("*", 1000000), but it seem don't have any effect. I added also the following code to the service's web.config, without success:

<system.web>
  ...
  <httpRuntime maxRequestLength="40960" />
</system.web>
...
<system.webServer>
  <security>
    <requestFiltering allowDoubleEscaping="true">
      <requestLimits maxAllowedContentLength="2147483647" />
    </requestFiltering>
  </security>
</system.webServer>

I guess it is a matter of configuration to allow this amount of data flow through the OData Service, but I can't find tho good place where I should change the default behavior.
