I want to build an app that gets data from a server and it displays it in xaml. I'm new to universal programs and in windows store apps in general. I haven't found anything useful yet as ms sql solutions require libraries that is not allowed for universal store apps :(
P.S.: The answer in how to connect sql server 2008 R2 with windows store application did not answer my question, but Jeffery's answer did.
You can’t connect to a MS SQL Server directly from the Windows App. The common way is host a data service and the app query the data through the REST API.
App -> data service (e.g. OData service) -> database (e.g. MS SQL Server)
In this case, you can deploy the SQL Server Data Service on IIS.
How to: Deploying OData Services using IIS & SQL Server
Then you use the HttpClient to retrieve the data from service.
