Xamarin and TLS1.3 - xamarin.forms

I am performing an HttpClient for a website with TLS1.3.
On my main phone as well as on the emulator, it runs smoothly.
In an old cell phone (Android 6.0) that I have for testing, it takes absurd 2min15sec.
Is there anything I can do to improve this performance?

Meteor for non-internet mobile app

I am developing a mobile app for iOS, Android, Windows mobile in Javascript and try to select in between Meteor and Backbone. The app will not include internet connectivity functionality. This app needs to store data on the device, not on a remote server.
I am a newbie in Meteor and have some experience with Backbone, and I am a developer with a strong inclination to having a one tool, ok least minimum number of tools, for deploying to every platform.
I need to write my app in a single code base, and deploy to 3 platforms iOS Android, Windows Mobile.
The Reactive nature and package management of the Meteor attracts me to itself from Backbone.
Is Meteor a suitable tool for developing non-internet connecting mobile apps for those platforms iOS Android, Windows Phone?

As #Dai mentioned in the comments above, Windows Mobile 6.x is now unsupported (and hardly used by anyone). To create apps for Windows Phone (7.x and 8), check out Visual Studio Express 2012 for Windows Phone (it's FREE). It has everything you need to get started creating apps for Windows Phone - http://www.microsoft.com/visualstudio/eng/products/visual-studio-express-for-windows-phone
Also check out dev.windowsphone.com for sample code, videos, blogs, and more. This is where you also go to sign up for a developer account that allows you to publish your app (this is typically $99/year although if you pay enough attention to the Windows Phone ecosystem, you can almost always find several contests running where you can win a developer token giving you a free year).
One last note... if you're interested in creating HTML-based apps for Windows Phone, you might check out PhoneGap. It allows you to create cross-platform, HTML5-based apps that are hosted within a native app shell (i.e. hybrid apps) - http://phonegap.com/

iis app slow loading on first and second request

I'm encountering this weird problem with one IIS Website / app:
The problem is that when i open a web browser on certain devices and access to the app, the FIRST and SECOND requests are EXTREMELY SLOW. It takes up to 30 seconds each to load.
After that everything runs smoothly.
This happens only after opening the web browser on CERTAIN devices.
I'll name the devices that the problem persist on and the ones that doesn't.
Devices with the problem:
Galaxy S 1 (cyanogen Mod 10)
Iphone 4S (stock)
ViewSonic VSD220 (runs android ICS)
Toshiba Laptop (win vista, i dont have the specs in hand)
Devices not showing the problem:
4 PC running win xp
Dell laptop (win 7, i dont have the specs in hand either)
The only common factor I've found is that the problem persist only with this APP on mobile devices.
In the laptop scenario i tried with both network cards (wired and wireless) and the results are the same.
I already tried with 2 different IIS servers and different versions (5.1 and 6.0). In different machines...
Creating a new the application pool on the 6.0 IIS server...
the APP pool recycle timer...
Also this is the only APP i have using .net framework 4.0
any suggestion or help would be really appreciated.
Based on our troubleshooting above, it's determined that some of the app's devices only have LAN connectivity and thus could not access external resources that were referenced in the app.

iPad Ad hoc version not run on the device

I'm facing a problem when running the AdHoc distribution app, I've developed an application and test it using development certificate on real device, running successfully, but when produce the adHoc and send it to my client to test it, the application installed successfully but does not run, where is the problem in this case?
the application using large image file (about 3-5 MB each image, but the number of the image is small, about 5-6 image) how can it run on the development certificate ?
Solution:
It seems that the tested ad hoc device was using a 3.4 ios version, and the app was developed for ios 5 and was contain some feature of the ios 5, so it was crashing every time the app run.
thx in advance.
