I am working on an application in Xamarin for Visual Studio 2017. I am attempting to test my application on Android and iOS live player devices.
When I try to run it, I get the following error on my device (Android and iOS):
Level=Error, Title=Visualization Error, Message=Encoding 1252 data
could not be found. Make sure you have correct international codeset
assembly installed and enabled. (NotSupportedException)
I have found similar issues through Google searching, but after making the changes, it still will not run. I have checked all Internationalization options for both devices, and I have even saved directly as UTF-8 encoding, as I figured it may be an issue with encoding windows-1252. I also referenced the I18N.dll to the I18N.West.dll for both.
Any help would be greatly appreciated. Thank you.
Update:
I have been able to narrow down the issue further.
using (SqlConnection sqlConn = new
SqlConnection(Configuration.ConnectionString))
{
//sqlConn.Open();
}
The .open was causing the encoding error. After commenting it out, the app will run on the live device, however, I now get:
Level=Error, Title=Uncaught Exception, Message=Encoding 1252 data could not be found. Make sure you have correct international codeset assembly installed and enabled. (NotSupportedException)
And Visual Studio 2017 throws the following error
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
at
using (SqlConnection sqlConn = new
SqlConnection(Configuration.ConnectionString))
It occurs the moment it tries to pull from the database at the using statement above. I am using SQL Server 2008 R2. All I can tell is that it is having an issue with sending to and receiving from the SQL Server with Android and iOS.
Update 2:
After using some Exception Handlers, I boiled it down to this inner exception:
{System.NotSupportedException: Encoding 1252 data could not be found. Make sure you have correct international codeset assembly installed and enabled.

da.Fill(ds);
From the "iOS Build" Project Options page in Visual Studio for Mac you should check "west" checkbox. Same for Android properties.
In the the Android project, go to Properties -> Android Options
Then Linker Options, in the "Additional supported encodings" check "West".
For VS2019, on windows : Check : 'Additional Supported Encodings'

I am trying to run several method of a dll library that I own. I use pythonnet 3.0.0dev, python3.9 and Mono 6.10.0. One of the methods triggers creating an .mdb file. On a windows machine I've install Microsoft Access Database Engine (suggested by the dll provider) and I could run my script without any problem. However, doing the same on a Mac OS X triggers the following error:

I'm trying to connect my Unity project to SQL Server. I have connected my Windows Forms application in Visual Studio 2017 successfully. And I think if copy the exact code in a unity script my goal should happen. I have imported System.Data.Dll V3.5 to my assets and using unity2018.2.1.f1.

You cannot use ODBC in Unity due to limitations in Mono. Use http://github.com/dotnet/SqlClient instead.
Your specific error is related to the differences in how machine names are resolved in Mono versus the ancient version of .Net framework of the WinForms era. DESKTOP-PVB5MHG will not be a valid DNS name, while Mono only uses DNS to resolve Data Source.
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 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.

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.
