// This sample requires the .NET Framework 4.0.
// To get this the sample to work, perform the
// following steps:
//
// 1. Create a new Web Site in Visual Studio 2010
// 2. Add a new Web Form (name it what you like)
// 3. Make sure the "Place code in separate file" is unchecked in the
// Add New Item dialog
// 4. Replace the entire contents of the .aspx file with the entire
// text of this sample
// 5. Right click on the project node in Solution Explorer
// 6. Select Add Service Reference
// 7. Enter service endpoint URL into the Address field
// For this example, we are using the dc container and the url is http://ogdi.cloudapp.net/v1/dc
//
// The Ogdi.DataServiceContexts sample makes it
// very easy for .NET developers to query
// for data using LINQ. This sample is uses code
// generation and will enable you to automatically
// generate updated classes as new data is published
// into OGDI.

// See http://ogdisdk.cloudapp.net/DataCatalog.aspx
// for a full list.

// Currently, the OGDI service only supports the $filter
// and $top WCF Data Services querystring paramaters.
// Therefore, the following queries are valid:
query = (from locations in context.BankLocations
select locations).Take(5);
// The query above translates into the following URL:
// http://ogdi.cloudapp.net/v1/dc/BankLocations()?$top=5
query = from locations in context.BankLocations
where locations.name == "Adams Bank"
select locations;
// The query above translates into the following URL:
// http://ogdi.cloudapp.net/v1/dc/BankLocations()?$filter=name eq 'Adams Bank'
query = (from locations in context.BankLocations
where locations.name == "Adams Bank"
select locations).Take(5);
// The query above translates into the following URL:
// http://ogdi.cloudapp.net/v1/dc/BankLocations()?$filter=name eq 'Adams Bank'&$top=5
// Although $filter is supported, not all $filter options
// are available. For example, substringof() is not supported.
query = from locations in context.BankLocations
where locations.name.Contains("Adam")
select locations;
// The query above translates into the following URL:
// http://ogdi.cloudapp.net/v1/dc/BankLocations()?$filter=substringof('Adam',name)
// Any LINQ queries that translate into usage of unsupported
// WCF Data Services querystring parameters will
// result in a DataServiceQueryException.
// As another example, the query below will result in the usage of $skip.
// Therefore a DataServiceQueryException will be thrown.
query = (from locations in context.BankLocations
where locations.name == "Adams Bank"
select locations).Skip(5).Take(5);
// The query above translates into the following URL:
// {http://ogdi.cloudapp.net/v1/dc/BankLocations()?$filter=name eq 'Adams Bank'&$skip=5&$top=5
