Can my libspotify operate offline? - spotify

I have a Windows .Net application integrated successfully with libspotify.dll (Version 11). I would like it to operate in offline mode, i.e. when login responds with UnableToContactServer? If this is possible (Premium Account) how is it best done?

Possible to remotely update Windows 10 IOT Core App without Azure or Windows Store?

I am in the process of finishing up a Windows 10 IOT Core app to be deployed on Raspberry Pi 3 devices for a single location beta test. The app is consumer facing and reads from a sensor so I am sure there are going to be at least 1 or 2 updates per week as we perfect the app. Everything I am reading says you can only achieve app updates from Windows Device Portal, Windows Store, or Azure.
Windows Device Portal works fine for local management/deployment right now but won't work remotely because the devices will eventually be installed all throughout the country behind different firewalls, etc. We don't want to have to keep up with customer firewall port forwarding.
Windows Store probably won't work because we don't want to have to wait for up to 48 hours for update approvals. Also not sure if Windows 10 IOT fully supports Windows Store yet.
I have not figured out how Azure IOT Hub manages app updates but I would really like to avoid having to use Azure if possible since we prefer to keep everything on our own servers and not pay cloud providers for stuff we can do on our own servers.
Has anyone figure out how to run a background service to download an app update and apply it?
I am just going to have to deal with Azure IOT Hub?
There is another option: Using OMA-DM.
Using OMA-DM: The app is updated using an OMA-DM compliant device
management channel such as Intune or System Center Configuration
Manager (SCCM)
The OMA-DM interface is supported in Windows 10 IoT Core and any
OMA-DM compliant management solution can be used to install and update
applications. Read the documentation for EnterpriseModernAppManagement
CSP for usage instructions.
NOTE: Some information of EnterpriseModernAppManagement CSP relates to prereleased product which may be substantially modified before it's commercially released.
You do need a type of (online/internet) service to connect to your IoT Core devices. Reference:
Microsoft Store: The app is published and updated from the Microsoft Store
Using Component Update Service: The app is published to Windows Update and updated like any other OEM package (driver package) Coming soon
Using Azure IoT Device Management: The app is published to Azure Storage and updated through the Azure DM channel New for Windows 10, version 1709
Using OMA-DM: The app is updated using an OMA-DM compliant device management channel such as Intune or System Center Configuration Manager (SCCM)
With Store, you'll be using the Microsoft Store service; Azure IoT Device Management will be using Azure IoT hub; OMA-DM can use Intune/SCCM or your own infrastructure (OMA-DM Server)

access azure mobile from windows 7 net4.0?

we are using Azure Mobile Service to store some data from Android, iOS and WP8 clients. This works fine.
Is there any way to access this data with .Net 4.0 from Windows 7 ?
The Azure Mobile SDK requires Net 4.5 but we still need to target 4.
The best (and at the same time the hardest) way would be to use the REST API directly. The SDKs are just a wrapper for this API.

Windows Azure Access Control and Windows Phone 8

I'm currently developing an app which has single sign on via Windows Azure Access Control Service. I am using the Access Control Service for Windows Phone NUGET package (the same control can also be found in the Windows Azure for Windows Phone toolkit).
I am just wondering if there is a new way of doing this in Windows Phone 8?
These current controls haven't been updated for about a year and a lot seems to have changed since then. I have searched but search engines still seem to be returning Windows Phone 7 results mostly.
Azure Mobile Services (still currently in preview) has new functionality designed to help make user authentication easier. See http://www.windowsazure.com/en-us/develop/mobile/tutorials/get-started-with-users-dotnet/

Monotouch - Windows Azure toolkit

I am working on an Iphone application which needs a direct access to Azure. I know there are toolkit versions exist for Objective C and Android. Is there any ported version of the toolkit exists for Monotouch?
There is no specific Azure SDK which is designed for MonoTouch and the Azure desktop binary are not compatible. If you decide to use MonoTouch, you would need to use WebClient API to create your own HTTP/HTTPS connection something similar to as described here, which could be comparative complex. On internet you may find some experiment level code to use Azure services and MonoTouch application so you may be by your own to try to get things working.
If you choose Objective C then you can use iOS SDK for Windows Azure which is far better solution. I personally will not use MonoTouch to develop application on iOS devices, if I am heavily dependent on Windows Azure Services, instead I will choose iOS Windows Azure SDK to connect Azure Service through native code.
Check this out as well: MonoTouch connect to Azure ACS, Azure SQL / Azure WCF

Can Metro apps be created for internal / limited distribution?

Is there (or will there be) a distribution channel with Windows 8 that allows Metro apps to be built for internal company use only, or for a select group of partners? Or is the app-store the only possible route?
The Primer for current Windows Developers on Microsoft's site indicates that for Metro apps,
Side-loading is available for enterprises and developers.
So, yes, you can side load applications, but it's currently limited to individual developers and enterprise customers.
The TechNet article on Managing the Windows Store provides more details:
Sideloading, which is available in both Windows 8 Consumer Preview and
Windows Server “8” Beta, refers to installing apps directly to a
device without going through the Windows Store. LOB apps do not need
to be certified by Microsoft and cannot be installed through the
Windows Store but they must be signed with a certificate chained to a
trusted root certificate. It is recommended that IT administrators use
the same technical certification that is done by the Windows Store on
LOB apps.
The TechNet Article on How to Add and Remove Apps provides the specifics on how to sign and side load applications on Windows 8 and Windows Server 8.
