LazyLoading is not working

[christian_bertram]

I have a problem with the lazy loading functionality of EF6. I want tu use it (loading by "Include()") but it just doesn´t work.
Everything i tryed had absolutely no effect and i cant figure out why.

I have tryed following approaches:

changing the edmx xml:

Code: Select all

<EntityContainer Name="MyEntitiesContext" annotation:LazyLoadingEnabled="false">

setting the lazyloadingenabled attribute:

Code: Select all

public MyEntitiesContext() : base("name=MyEntitiesContext", "MyEntitiesContext")
{
    this.ContextOptions.LazyLoadingEnabled = false;
    OnContextCreated();
}

setting the attribute right before using the context:

Code: Select all

    context.Configuration.ProxyCreationEnabled = false;
    context.Configuration.LazyLoadingEnabled = false;

i even added set the SerializerSetting for web api:

Code: Select all

public static void Register(HttpConfiguration config){
config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
}

Nothing helps, the navigation properties of my entities are still created. During debugging i can navigate deeper and deeper and my application crashes during serialization to json.

The only possible way is to delete the navigation properties in my edmx model (database first) but thats not a solution because of course i want to use my entites without manually combining them.


Any solution?

I´m using .net 4.6, Ef6, the newest dotconnect and database first. (i'm creating a dll with the context in one project and use it in my web application)

Please try the sample described at http://forums.devart.com/viewtopic.php?t=20908. It works in our environment, tested both ways:
a) context.ContextOptions.LazyLoadingEnabled = false;
b) <EntityContainer Name="MyEntities" annotation:LazyLoadingEnabled="false" ...>

JIC: Lazy Loading is a feature of Entity Framework engine (no support in provider is required).

Hi, the configuration finally works for me but i still dont have a clue why it did not work.
I created a new EDMX model. Maybe tthere was a problem with it.
