I have a bizarre problem.
I have implemented a standard Service Stack API.
It has been working perfect for the last year now.
Last week I saw some major changes to Xamarin Studio so decided to update my IDE.
With that update NuGet comes standard, so I decided to convert my Service Stack Reference Files to use NuGet. Quite nice, now I can update the DLL's etc with 1 click.
So the API works fine on my Windows Machine now, no issues.
Problem: Our servers run Ubuntu with Mono installed. And it does not want to budge.
I Initially get this Error:
System.TypeLoadException: A type load exception has occurred.

at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0
Then I refresh the page and I keep getting this error:
System.IO.InvalidDataException: ServiceStackHost.Instance has already been set
at ServiceStack.ServiceStackHost.Init () [0x00000] in <filename unknown>:0
at API_NOTIFICATION.Global.Application_Start (System.Object sender, System.EventArgs e) [0x00000] in <filename unknown>:0

Anyone Experienced this before? Anyone know how to fix this?
I did look at other posts similar to this one.
No idea where to find:
App_Start/ServiceStackFramework.cs
And no idea how to remove as again I cant find that anywhere. But who knows, it might not even be the same problem at all.
I have used the standard Tutorial to set up the API which is posted on the ServiceStack Website.
Any help will be much appreciated. And like I said, the only think that really changed is the IDE and updating those ServiceStack references via NuGet.
AppHost:
public class ResponseNotificationServiceAppHost : AppHostBase
{
public ResponseNotificationServiceAppHost() : base("Response Notification Services", typeof(NotificationServices).Assembly)
{
}
#region implemented abstract members of AppHostBase
public override void Configure(Funq.Container container)
{
}
#endregion
}
Global:
public class Global : System.Web.HttpApplication
{
protected void Application_Start(Object sender, EventArgs e)
{
new ResponseNotificationServiceAppHost().Init();
}
}
API Service Class:
public class NotificationServices : Service
{
public PersonNotificationResponse Any(PersonNotification request)
{
// Implementation Code here
}
}
Update:
When trying to remove the AppHost, the API would not load. I get the following error on the Ubuntu Server:
System.NullReferenceException: Object reference not set to an instance of an object
at ServiceStack.HttpHandlerFactory..cctor () [0x00000] in <filename unknown>:0
Looks like it was a problem with the mono framework.
The server was running on 2.10.5 Mono on a 12.04 LTS server.
I hosted the API on a new 14.04 LST server with Mono 3.2.6 installed.
Works fine now.
Maybe ServiceStack was updated which was not compatible with 2.10.5 anymore. Not sure, can only speculate.

I can't use UITest anymore with my xamarin project since the last update of xamarin on the stable channel with Xcode 8.2.
Everytime, when I launch the test, I have an error : "SetUp : System.InvalidOperationException : Sequence contains no matching element". My test series doesn't change from a long time and works well before...
So I don't know how to correct this problem now...

Thank you!
try to grab the newest Xcode and
then beside proper NUnit version (2.6.x and proper NUnitTestAdapter 2.1.0)
try do upgrade/downgrade the Xamarin.UITest package to version 2.5.
For me it was not working (with same error) for 2.7 for 2.5 it's ok.
Regards,
I am working on an existing Xamarin iOS application with a PCL and uses MvvmCross for IoC and Databinding. Built on MvvmCross 3.1.1
The App looks like a TabControl App but it is buttons on the MainViewCotnroller giving the Tab feel to it. Views are declared in the Storyboard and in the MainViewController,
PrepareForSegue(UIStoryboardSegue segue, NSObject sender) method
is overridden to load the selected "Tab" View based on the Segue selected - like below
if (segue.Identifier == "FirstSegue")
{
var dest = segue.DestinationViewController as FirstView;
dest.Request = new MvxViewModelRequest<FirstViewModel>(null, null, new MvxRequestedBy());
foreach (UIView v in src.placeHolderView.Subviews)
{
v.RemoveFromSuperview();
}
dest.View.Frame = new CGRect(0f, 0f, w, h);
src.placeHolderView.Add(dest.View);
}
The App runs fine on iPhones with iOS 7.1 till 8.4.
Just before iOS 9 was released I did a test installation for the App on iPhone 6 with iOS 9.1 beta and the App crashed on loading. I retrieved the device logs (below) and analysed that the problem is in the guts of the MvvmCross ViewDidLoad method. I updated the latest SDKs (XCode 7, Xamarin.IOS 9.0) and followed instructions provided by Xamarin and compiled the App again using the latest SDKs same error. Updated the Nuget package reference for MvvmCross to 3.5.1 and still the same issue
The issues is there is a null reference at Line 44 in the 3.5 MvvMCross Source Code in GitHub
Note: This piece of code has not changed since 3.1 at least and 3.5.1 is the latest in the nuget for MvvmCross

In short :
Only in iOS 9.1, MvvmCross 3.1.1 AND MvvmCross 3.5.1 has a NullReference Issue in line 44 of the MvxViewControllerExtensionMethods class which gets called during ViewDidLoad but works well with iOS 8.4 and below
I am just getting familiar with MvvmCross framework and unsure whether it is an issue with MvvmCross and iOS 9.
Has anyone come across this issue? Any help on this would be appreciated.
Note: The MvvmCross samples work fine with iOS9. So I believe it has to be something with the Tab implementation.
One thing is that MvvmCross 3.1.1 not is build for iOS unified code. This will prevent you from submitting your app. MvvmCross 4.0 is currently in beta, but i would recommend using it, because it has many fixes.
If the code crashes on line 44 while trying to resolve IMvxViewModelLoader, it probably means that you are missing some package where the IMvxViewModelLoader is.
I just installed MonoDevelop 5.0.1 in Ubuntu 12.04 and tried to compile a simple Hello World.
This results in the following build error:

I looked through the options and everything I found seems to be set up correctly. Edit>Preferences>Projects>.NET Runtimes has Mono 3.2.1 included.

The same error already occurred in MonoDevelop 2.something from the Ubuntu package manager.
I can't help you with the solution may be, but I can give you why this is happening -
Please visit this links -
The reason http://msdn.microsoft.com/en-us/library/ydy7a2we(v=vs.90).aspx
Mono Develop System Requirements.
http://monodevelop.com/developers/building_monodevelop
Make sure that MonoDeveloper supports the Mono version you are using.
I (think I) found the issue and now it appears to be working correctly. Apparently, one of the project files was corrupted for some reason. Deleting the old project and creating a new one helped.
I found a really strange problem while creating unit tests that only occurs with the Mono runtime (Xamarin on Mac included), but runs fine within Visual Studio. I isolated it as far as I could, and I reached a point that I can't tell if it is a bug with Mono, Moq or Castle DinamicProxy, although it only crashes when using the Mono runtime.
This is the code:
using System;
using System.Collections.Generic;
using Moq;
namespace ConsoleApplication1
{
public interface ISomething<T>
{
List<T> DoSomething<U>(/*Func<T, U> expression*/);
}
public class Foo { }
public class Program
{
public static void Main(string[] args) {
var mock = new Mock<ISomething<Foo>>();
Console.WriteLine(mock.Object);
}
}
}
Here's that I know:
It compiles and run with within Visual Studio 2012. The output is "Castle.Proxies.ISomething`1Proxy"
It does not work when running with the Mono runtime. An exception is thrown (see below)
If I change the declaration from an interface to an abstract class, it works with Mono
If I change the return type from List<T> to anything else, it works with Mono
If I remove the generic type <U>, it works with mono
Got the same results under Windows, Mac and Linux using the command line build from http://mono-project.com
In Windows it fails with Mono 2.10.9, but works within Xamarin.Studio (4.0.10)
In Mac, it fails within Xamarin.Studio (4.0.10)
I recompiled Moq linking agains the latest DynamicProxy release (Castle.Core.3.2.0), with no changed to the behaviour.
Although I've found this problem when using Moq, but I can't tell if it's related to it or even DynamicProxy. The partial exception is below, complete can be found at http://pastie.org/8203093

I am creating a net.tcp based WCF service to control one of our backend applications. During development and testing on a Windows machine everything worked as expected.
However when I tried to run the very same application using Mono on either the same Windows box (Mono 2.10.6) or on Debian Squeeze (with Mono 2.10.5), I suddenly get a TypeLoadException in the ChannelFactory.
In the end it comes down to just this call that fails:
controlHost = ChannelFactory<IControlServiceContract>.CreateChannel(
new NetTcpBinding(SecurityMode.None),
new EndpointAddress(endpointAddress)
);
With this definition for IControlServiceContract in another assembly:
[ServiceContract]
public interface IControlServiceContract
{
[OperationContract(IsOneWay = true)]
void Ping ();
[OperationContract(IsOneWay = true)]
void Shutdown ();
[OperationContract]
int GetCommandCount ();
}
Which runs fine when started directly (i.e. using .NET).
When executed using mono --debug --runtime=v4.0 though it crashes with this super sweet stack trace:
! Ein Fehler ist beim Erzeugen des Kanals auf net.tcp://localhost:34684/watchdog/watchdog.ctrl/ aufgetreten

I would go ahead and first thing submit it in http://bugzilla.xamarin.com/
Then maybe hangout in irc://irc.gnome.org/mono , and poke Atsushi Enomoto (nick "eno") which is the maintainer of WCF, to see what he thinks.
