This question is answered by understanding how Entity Framework works internally. I'll try to highlight the key features here.

Change tracking

Entity Framework has a sort of cache of entities in-memory, called the change tracker.

In your first example, when you fetch an entity from the database:

Is there a way to pass the DbSet into the page?

Asked 2020-Oct-13 at 00:57

I have the window with the page. The page displays a data from the my database. Also, on the window the buttons are placed, whose contents is according to the tables names of the database. These buttons switchs the page's content.

For example, this is the btnUsers button's click event, which displays the "Users" table:

I found the solution, and it doesn't use the generic page.

Well, when I tried to print the table content, I discovered, that pass a structured query into the TableTemplate.Init(). I remember, that never used the dbContext.TableClass as a function argument before, always converting the TableClass into the list.

I confess, I don't understand the EntityFramework and didn't expect such a result. Generally, I used the object type and already forgot why used the dynamic type...

I decided to pass the DbSet, converted to the list (and this, as I understand it, are the different thigns) into the page's constructor, instead of the DbSet. But, because I doesn't use the general page, I converted the items of this list into the object:

I seen some solutions about multiple active result sets in the connection string, but apparently thats a workaround and not a solutiuon.

Well I think I am really stupid, I just transformed my code into something really dumb (anemic model) and the problem went away.

What I figured out was that the backing field being a IList and the Property of type IReadOnlyList and the proxy couln't create the type.

The exception error was not much helpful in this case but changing IList to List fixed my issue.

I suspect your model name is incorrect hence not binding to the magic string, your model name and the string should match the DropDownList signature in your DropDownList

Why dont you use DropDownListFor its a better option, and you can see an example here

Change to, thats a magic string not binding.

The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Urun_C7B3883A1159F8EE0177C29B1CA535182B157B3C5BB798ABCC8C2A72FB5CFED9', but this dictionary requires a model item of type 'Tututuncu.Models.UrunFotoViewModel'.

ANSWER

Answered 2020-Mar-11 at 16:39

You have two model types.

Parent: @model IEnumerable
Partial: @model IEnumerable

You're calling Partial using @Html.Partial("FotoListele")
You can use @Html.Partial("FotoListele", THE-NEW-MODEL-OF-LIST-UrunFoto)

When using Partial without passing the new model, it uses the parent model. Thus, it gets exception when trying to perform the casting.

You can either create a new Model that fits the Partial needs, or accept the parent model.

Note: partial class doesn't relate at all to razor engine Html.Partial. more on that Here

Instead of:

GetMethod("Cast")

...try this overload:

GetMethod("Cast", new Type[] { typeof(Object) })

More observations...

The Cast method of class form_base is not static. (See above to get this one.)

The class form_base doesn't define any public static methods.

(Side note, I'm not sure why the class extensions is defined as partial.)

The Cast method in class extensions is static, but is not an extension method.

To get this one, you can use this overload, on type extensions:
