(VB.NET MVC) Модель элемент передается в словарь типа «System.Data.Entity.DynamicProxies

Question

Я постоянно получаю свою ошибку:

The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Project_AEA0128FB0789822CECB09AA20866E2B89F29798BE9DFF48A921561C8509DA33', but this dictionary requires a model item of type 'webapp.ProjectModel'.

Это мой прибудет Просмотр код:

' GET: Projects/Edit/5 
Function Edit(ByVal id As Integer?) As ActionResult 
    If IsNothing(id) Then 
     Return New HttpStatusCodeResult(HttpStatusCode.BadRequest) 
    End If 
    Dim project As Project = db.Projects.Include(Function(i) i.Info).Include(Function(p) p.Files).Where(Function(w) w.Id = id).First() 
    If IsNothing(project) Then 
     Return HttpNotFound() 
    End If 
    Return View(project) 
End Function 

И это мой взгляд модель:

Public Class ProjectModel 
    Public Property Id As Integer 

    <Required> 
    <Display(Name:="Project Naam")> 
    <MaxLength(250)> 
    Public Property Naam As String 

    <Required> 
    <DisplayFormat(NullDisplayText:="NotSpecified", DataFormatString:="{0:dd-MM-yyyy}")> 
    <Display(Name:="Begin Datum")> 
    Public Property BeginDate As Date 

    <Display(Name:="Eind Datum")> 
    Public Property EndDate As Date? 

    <Required()> 
    <Display(Name:="Project Manager")> 
    Public Property ProjectManagerId As String 

    <Required()> 
    <Display(Name:="Google Map Link")> 
    Public Property GoogleMapLink As String 

    <Required> 
    <Display(Name:="Address")> 
    <MaxLength(250)> 
    Public Property Address As String 

    <Required> 
    <Display(Name:="Description")> 
    <MaxLength(250)> 
    Public Property Description As String   
End Class 

И это само по себе вид:

@ModelType Webapp.ProjectModel 
@Code 
    ViewData("Title") = "Edit2" 
End Code 

<h2>Edit2</h2> 

@Using (Html.BeginForm()) 
    @Html.AntiForgeryToken() 

    @<div class="form-horizontal">

      </div> 
     </div> 

     <div class="form-group">

     </div> 
    </div> 
End Using 

<div> 
    @Html.ActionLink("Back to List", "Index") 
</div> 

Я не знаю, откуда эта ошибка или как ее исправить.

Любые идеи или исправления будут оценены.

Ваш взгляд ожидает модель типа Webapp.ProjectModel, но вы передаете свой Project модель непосредственно вместо этого. Вам необходимо преобразовать Project в ProjectModel в действие «Изменить», прежде чем отправлять его в свой вид.
