When I got this error, it was because I had an error/omission in my ResponseType definition (WebApi). The compiler was fine with it, but Swagger wasn't.

I've been working on this for the last 3 hours and haven't found a good resource or solution to this problem. I've followed the directions found in Microsoft's documentation to change my ASP.net Privatekey from a string to an int. Since then, I have been presented with the following error:
FormatException: Input string was not in a correct format.
The app will not load past this method in the program.cs class:
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
I have hit a roadblock and any help with this issue would be appreciated.

I think the problem may be that the login of your previous user may be completed when the ID is a string.
You now change it to int, so now it no longer knows what to do with the string.
I think the simplest solution is that you should delete the cookie, log out and log in again (use int instead).
I have created a project that makes use of Catel, Entity Framework 6 and Syncfusion Community Edition. Specifically I am using the sfDataGrid from Syncfusion.
I have come across an issue that has me completely stumped, maybe someone out there could point me in the right direction.
I have a Catel UserControl with a sfDataGrid in it. The ViewModel has an ObservableCollection (Catel Property) of the data I am using as the ItemsSource for the sfDataGrid. I have filtering enabled on the sfDataGrid. Here is the code for the sfDataGrid:
<sync:SfDataGrid
x:Name="ItemsDataGrid"
ItemsSource="{Binding MyItems, Mode=OneWay}"
SelectedItem="{Binding MyItem, Mode=TwoWay}"
AutoGenerateColumns="False"
AllowFiltering="True"
AllowResizingColumns="True"
GridCopyOption="IncludeHeaders"
GridPasteOption="None"
ShowGroupDropArea="True"
ShowRowHeader="True"
DataFetchSize="50">
<!-- Columns -->
</sync:SfDataGrid>
I add a new Item to the collection on a different view and then I save it to the datacontext and refresh the list:
private async void OnNewMyItemExecute()
{
MyItem= new MyItem();
MyItemsRepository.Add(MyItem);
var myItemsViewModel = TypeFactory
.Default
.CreateInstanceWithParametersAndAutoCompletion<myItemsViewModel >(MyItem); //the construction has parameters for IUIVisualizerService, IPleaseWaitService, etc.
if (await _UIVisualizerService.ShowDialogAsync(myItemsViewModel) ?? true)
{
var myItem= myItemsViewModel.MyItem;
await InitializeAsync();
MyItem = myItem;
}
else
{
_UnitOfWorkService.Rollback(); //just undo some changes
MyItem = null;
}
UnitOfWork.SaveChanges();
}
Creating a new Item is not a problem at all, the thing that is weird is that after I created a new Item and then attempt to filter grid on any column of the sfDataGrid (click the filter button in the column header, a filter popup opens, enter a value in the criteria textbox and click 'OK'), I get this:
MyProject.vshost.exe Warning: 0 : 17:57:49:075 => [WARNING]

I have tried opening MyItemsView with .ShowAsync(), .ShowDialogAsync() and before I upgraded to Catel 4.4 I also used .ShowDialog(), but it made no difference. I could turn Proxy Creation off in EF, but that would cause a lot of changes I have to make in my project (no more lazy loading for me, and that is not an option). I do believe the problem being the new Item I add not being a Dynamic Proxy, and getting it to be a Dynamic Proxy would probably solve the issue, but I have tried loading all the data from the DbContext again, but it also does not solve the problem.
Any advice would be appreciated.
The issue is this:
System.InvalidCastException: Unable to cast object of type 'MyProject.Domain.MyItem' to type 'System.Data.Entity.DynamicProxies.MyItem_4CA6F59AB53174892ED9EFBC1D3CC07B862579FC3C5733C6CF4DE857907CFF9C'.
The reason is, of course, that you are trying to cast a base type to a derived type (which it simply isn't). That this eventually results in the window closing is because an exception happens, but that isn't the real problem.
This exception occurs in the FilterRecord method of the grid. I am not sure if that is something you have written yourself or something that is inside syncfusion, but that is the place to look.
The reason you have generated proxies is because you enabled (or it's enabled by default) the proxy generation of the Entity Framework DbContext.
I have an object Employee containing lots of information on an Employee, such as his Login, Name, LastName, e-mail address etc.
After retrieving all the information imputed on the edit page of an employee, I then call the following to update the object :
public Employee Edit(Employee objEmployee) // Work on EDIT
{
var Original = Get(objEmployee.Login);
_entities.Employees.Add(objEmployee);
_entities.SaveChanges();
return objEmployee;
}
Once it reaches SaveChanges() I get the following :

What could be causing that, and how may I solve it?
You need to update the entity and not to re-insert it:
public Employee Edit(Employee objEmployee) // Work on EDIT
{
_entities.Employees.Attach(objEmployee);
var entity = _entities.Entry(objEmployee);
entry.State = EntityState.Modified; // Mark as modified
_entities.SaveChanges();
return objEmployee;
}
I have a project include MVC and Web API controllers. I have,
GlobalConfiguration.MessageHandlers.Insert(0, new MessageHandler1());
But when I request a MVC controller it executes this handler. It hurting me because SuppressDefaultHostAuthentication is executing PassiveAuthenticationMessageHandler handler on MVC request. I have put a break-point on MessageHandler1.SendAsync and found that System.Web.HttpContext.Current.Handler = {System.Web.Mvc.MvcHandler} which confirm that it is MVC request.

I just fix it using custom MessageHandler,
GlobalConfiguration.SuppressDefaultHostAuthentication();
GlobalConfiguration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));
GlobalConfiguration.MessageHandlers.Insert(0, new ResetMvcPrincipalMessageHandler());
public class ResetMvcPrincipalMessageHandler : DelegatingHandler
{
protected async override Task<HttpResponseMessage> SendAsync(
HttpRequestMessage request, CancellationToken cancellationToken)
{
var url = request.RequestUri.AbsolutePath;
if (!url.Contains("/api/"))// not web api request
{
var principal = request.GetRequestContext().Principal;
var response = await base.SendAsync(request, cancellationToken);;
request.GetRequestContext().Principal = principal;
return response;
}
return await base.SendAsync(request, cancellationToken);
}
}
I receive this error when I am trying to serialise a entity framework class with a circular reference (POCO). It is unable to serialise the proxy class which contains a RelationshipManager.
I have tried to the 'ToList()' method listed here http://json.codeplex.com/discussions/214093, but still no luck. Any ideas?
Here is an example of the exception i am receiving.
System.Reflection.TargetInvocationException was unhandled by user code

If the problem really is in circular references check this thread for help. But you should not serialize your entities - if serializer tries to serialize RelationshipManager as well you should serialize custom objects instead of entities because RelationshipManager is "infrastructure" part of entity - it is not part of data you really need to serialize and most probably this part has no meaning for target system where you want to pass Json object.
