Azure MobileApp Client SDK crashes on Xamarin.Forms (Android)

The reproduce the error, I've created a blank mobile app and a new sql database.
Afterwards I've followed the quickstart guide and downloaded the backend and the Xamarin.Forms project.
I've deployed the Web-App to azure and started the Android app using the 5'' KitKat (4.4) XXHDPI Phone (Android 4.4 - API 19) emulator.
As soon as I add an item to the TodoItem - List (you see, it's the default sample app of xamarin mobile apps), the todoTable.InsertAsync call fails.
Unfortunately, there is no detailed error.
It's just a error message telling "An unhandled exception occured".
In the output window, I can see the following error:
03-01 19:48:33.781 I/MonoDroid( 1512): UNHANDLED EXCEPTION:
03-01 19:48:33.793 I/MonoDroid( 1512): Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException: The request could not be completed. (Internal Server Error)
03-01 19:48:33.793 I/MonoDroid( 1512): at Microsoft.WindowsAzure.MobileServices.MobileServiceHttpClient+<ThrowInvalidResponse>d__24.MoveNext () [0x001ec] in <42e24ce875d34485ad11c4f8aebb904a>:0
So I've had a look at the azure mobile app in the azure portal.
Before I've ran the tests, I've enabled almost all the logs.
I can see FREB-Protocols I can see a post request to /tables/TodoItem which failed with http 500. Unfortunately it does not tell my anything about the error itself. Authentification is disabled, so the authentification should not cause any problems.
I've included the whole log here:
https://1drv.ms/b/s!AqCo2Ottp6L6wC7-nOFkDN7cERE6
Does anyone got any idea what could be wrong? Sitting here since far to many hours, guessing what could be wrong.

The Internal Server Error means your service is crashing - that's why it is not producing any logs. You've not shared anything about your backend, but that is where your problem is.
Run the service locally and attach a debugger and step through the backend code. You can find details of running the service locally (attached to a local SQL instance) in the HOWTO documents on learn.microsoft.com.

Visual Studio '15 Web Deploy continuously failing

I'm trying to deploy an ASP.NET MVC 5 application to a shared hosting account (SmarterASP). It was working perfectly fine but recently it mysteriously stopped working for no reason. I tried contacting support, spent 2 days talking to them and they say "it's working fine for us, something's wrong at your end". I'm not sure whether it's my end. The task always fails with this:
3>Start Web Deploy Publish the Application/package to *url removed* ...
3>C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.Web.Publishing.targets(4295,5): Error : Web deployment task failed. ((12-Nov-16 3:07:55 PM) An error occurred when the request was processed on the remote computer.)
3>
3>(12-Nov-16 3:07:55 PM) An error occurred when the request was processed on the remote computer.
3>The server experienced an issue processing the request. Contact the server administrator for more information.
3>Publish failed to deploy.
Nothing else at all. No further error messages. Is there any I could get a detailed error message what EXACTLY is causing the process to fail? I'm already considering to move to a VPS if the issue persists.

MS Lightswitch - Getting error message on loading, but unable to find the actual error

I am using Microsfot Lightswitch, running my deployed applications as Virtual Directory in IIS. So far it is working fine. Since yesterday I am getting the error message right after successful login.
The application has stopped responding due to an error and needs to be restarted.
Error details: [Arg_NullReferenceException]
Arguments:
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.1.30214.00&File=mscorlib.dll&Key=Arg_NullReferenceException
I also used fiddler to trace the actual error, but still could not find. Here is the fillder's screen shot:
Can any body suggest what could be actually going wrong, or how can I reach to the actual real error?
Edit: It seems there is some problem with the read-line in fiddler, but I am unable to dig down the real error, actually I am new to fiddler.

NServiceBus exception and subscriber not able to read queue

I've been battling with this for a few days now with no luck. I've setup a NServiceBus project by following the guidelines on the getting started guide.
My MVC site successfully pushed messages onto my queue, but the subscriber never reads them off. No error messages until after about a minute, where the following pops up on the console:
2012-06-26 13:05:43,648 [1] FATAL NServiceBus.Hosting.GenericHost [(null)] <(null)> - Autofac.Core.DependencyResolutionException: An exception was thrown while invoking the constructor 'Void .ctor(Raven.Client.IDocumentStore)' on type 'RavenTimeoutPersistence'. ---> System.Net.WebException: The operation has timed out at System.Net.HttpWebRequest.GetResponse()
at Raven.Client.Connection.HttpJsonRequest.ReadStringInternal(Func`1 getRespo
nse)
at Raven.Client.Connection.HttpJsonRequest.ReadResponseString()
at Raven.Client.Connection.HttpJsonRequest.ReadResponseJson()
I can successfully connect to Raven via the web portal, and I can see my queues listed there - so am at a loss as to why NServiceBus cannot read the messages on the queue. I've reinstalled MSMQ, rebooted machine, re-installed NServiceBus - nothing seems to work.
Does anyone have any idea as to whats going wrong here?

This turned out to be another victim of Kaspersky Anti Virus. Even though firewall was set to "Allow all network connections", turning it off solved the issue.

Web Reference Help: No connection could be made because the target machine actively refused it

Ok, so I'm learning about ASP.NET by making a simple program to read in a user's gmail credentials and construct an email from their input into the Console, but I'm getting a new error that I was not get yesterday, and I have not changed ANY code. The error is on line 41, so I have provided that (the rest of the code is just reading input into Strings) I have disabled my firewall to no avail, and have also tried "http://localhost/Service.asmx", which doesn't work either. I've also tried restarting IIS.
I'm completely new to this subject, but the error suggests, to me, that the program is communicating with the server but is being denied by a blocked port, but I have disabled my firewall and the error persists. Any ideas? Thanks in advance!
/*40*/ Communication_Service.Service CommServiceProxy = new Communication_Service.Service();
/*41*/ Result = CommServiceProxy.SendMail(GmailAccount, Password, To, Subject, Body);
There was an error dowloading http://localhost:4932/Service.asmx. Unable to connect to the remove server. No connection could be made because the target machine actively refused it 127.0.0.1:4492

Sounds like you are running cassini (development server). The application at http://localhost:4932/ needs to be started. You probably have multiple sites and need multiple start up projects. Right click your solution and click set start up project, pick multiple, and select all your websites. On VS goto debug, run without debugging and they should all start.
