Usage of generic OpenAccessContext

[Hasan Oz]

Hi , I want to manually defineOpenAccessContext like this.

string connectionString = @"data source=192.168.5.217;initial catalog=xxx;user id=sa;password=xxx";

 XmlMetadataSource metadataSource =
              XmlMetadataSource.FromAssemblyResource(
                  Assembly.LoadFrom("BIS.Business.MainApplication.dll"),
                  "BisFrameworkEntityDiagram.rlinq");

           BackendConfiguration configuration = new BackendConfiguration();
           configuration.Backend = "mssql";

           OpenAccessContext context = new OpenAccessContext(
              connectionString, configuration, metadataSource);

My question , If I define context as a generic OpenAcessContext , how I reach to entites.

public void GetSystem(OpenAccessContext context)
{
     return  context.GetAll<Systems>().FirstOrDefault   ............
}

is the same with Scope.Extent<Systems>().FirstOrDefault   ........................

GetAll() method really gets all values?
 
Or is there any advice of you for usage of several context in one point. In old scope model this is easy with Extend method.
Thanks.

Hello Hasan Özgilik,

Yes, you can use the context.GetAll<T>() method. As you can see, the context endpoints call exactly this method which indeed calls internally scope.Extent<T>(). So the result at the end should be the same.
Hope that helps.

All the best,
