I want to build a Windows 8.1 Store app using C++. I want to be able to use Azure Mobile Services as a cloud backend for my app. My app is going to be a pure native app and from a performance perspective it is not acceptable to use some client SDK library which has been implemented in a managed language. How do I do this using C++ only?
With Visual Studio 2013, it is now possible to use a pure C++ based Azure Mobile Client library in your C++ Windows Store app. The following blog post contains more details about this:

I have basic understanding of .net and chatbot.
I wanted to integrate Amazon lex in xamarin(ios, android)app. There seems to be no example or sample. I have created chatbot from AWS platform intent and slots.
Also I wanted to use database to get query return. Any sample to integrate AWS Lex with Xamarin app would be helpful.
As I understand from your question, you already have some implementation of chatbot made with AWS services, but you are having issue on integrating it to your xamarin application to be able to use it in IOS and Android devices.
For that purpose, there is AWS Mobile SDK which happens to support also xamarin.
From their link:
https://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/Welcome.html
I also did not find a Lex tutorial directly, but a very promising quote:
Supported AWS services currently include, but are not limited to [narrow list of services]
was on the same page. I looked around, found this text:
The AWS Mobile SDK for .NET and Xamarin also allows you to use most of the AWS services supported by the AWS SDK for .NET. The AWS services specific to mobile development are explained in this developer guide. For more information about the AWS SDK for .NET, see [a link]
clicked the link and ended here:
https://docs.aws.amazon.com/sdkfornet/v3/apidocs/Index.html
and under link AmazonLex -> AmazonLexClient there was something, you probably wanted to see:
Version Information
.NET Standard:
Supported in: 1.3
.NET Framework:
Supported in: 4.5, 4.0, 3.5
Portable Class Library:
Supported in: Windows Store Apps
Supported in: Windows Phone 8.1
Supported in: Xamarin Android
Supported in: Xamarin iOS (Unified)
Supported in: Xamarin.Forms
Those 3 last let me understand that whenever you setup Mobile SDK, you get access to AWS services in Xamarin, also Lex.
Steps to install on
https://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/setup.html
mainly contain steps on how to create xamarin app and get AWS account, most important is to install the AWS Mobile SDK for .NET and Xamarin and configure it. More detailed steps are under that link.
After that the process is to follow the instructions on:
https://aws.amazon.com/getting-started/projects/bots-just-got-better-net-toolkit-lex-lambda-cognito/module-one/
like pointed in comments. I suppose once you have access to any service via Mobile SDK, the wire up of Lex may go in similar steps and no special just xamarin tutorial is not needed anymore.
It seems you are looking for both architecture and sample code for implementing AWS Lex bot with .NET backend that can be integrated with iOS/Android Frontend.
You have multiple choices here to do it
Build both chat user interfaces in iOS and Android and integrate them AWS iOS & Android SDKs to utilize the AWS LEX bot.
Just implement a bot user interface in iOS and Android app and integrate it with a .NET backend that can utilize AWS .NET SDK to integrate with your LEX bot.
I would recommend the second approach as it will save you writing the LEX integration code twice both in Android and in iOS. In the second appraoch you will be able to write a single integration for AWS LEX in .NET and that can give a unified experience across the mobile devices(iOS/Android)
Now for the .NET based backend integration with AWS LEX bot.
If you are an experienced .NET developer and you know how will you host your code then only thing that you need is the .NET API reference for AWS LEX, which can be found here
https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/Lex/TLexClient.html
But if you are not sure how to write this integration code and also not sure how the deployment will look like then you can follow the below tutorial
Bots Just Got Better with .NET and the AWS Toolkit for Visual Studio
Also, find here the architecture form the above tutorial
there is no direct solution like Amazon Lex is supported by React-native. i confirmed with xamarin team as well as AWS service one of the member. direct integration not possible.
I would like to know what is the real benefit of using azure web job sdk in web job.
I have some business logic to be executed without any interaction with storage,service bus.It is interacting with Sharepoint and Azure Sql. I have checked question here -Basic of Azure WebJobs SDK
which says JobHostConfiguration is not required for the job.
In which cases the JobHostConfiguration and webjobs sdk will be required and why we should use that?
WebJobs 3.x targets .NET Standard 2.0. This means you can use it from a .NET Framework application or a .NET Core 2.x application, the choice is up to you. If you want to make a .NET Framework application that uses WebJobs, then follow the same guide but with a .NET Framework console app as the starting point (instead of .NET Core).
If you're planning on deploying this webjob to a webapp that is running a .NET Framework application, I think it makes sense to use .NET framework for the webjob too.
You can refer here for more details on Webjobs Host.
Webjob SDK Version 2.x
The JobHostConfiguration class has a UseDevelopmentSettings method that enables development mode. The following example shows how to use development settings. To make config.IsDevelopment return true when it runs locally, set a local environment variable named AzureWebJobsEnv with the value Development.
Please let me know if this helps.
I have a requirement of integrate stripe into Qt Mobile application for android and ios. I searched on it but not able to find any suitable starting point. What are the possible solutions for me to integrate stripe in c++ applications.
So far there is no C++ API kit for Stripe.
All you can do by yourself from scratch.
Use curl to for Stripe API call.
Use a json c++ library for serialize/deserialize request/response.
I understand that there are iOS and Android libraries where there's no problem to use Dropbox Sync APIs. I also have an application developed for Windows desktop using Visual Studio 2008 and C++/MFC (or Win APIs).
Is there any tutorial how to implement that Dropbox Sync via plain https? (JSON or REST)
Underneath, everything is just a web API, so check out the Core API HTTP docs and go from there: https://www.dropbox.com/developers/core/docs.
I need to develope WAS application and should be hosted into Demandware platform. Can i develop the WAS application using tomcat and can host it into the Demandware or should WAS application be developed in the Demandware platform?
I am new to Demanware platform and WAS. Guide me.
You cannot build a web service outside of the UX Studio paradigm like what you described, but you can build a psuedo-service like pipeline in UX Studio that returns JSON, XML, etc. and it will work more or less just like any other REST service.
Demandware is Software as a Service (SaaS) provider, which will not allow you to access the underlying infrastructure (e.g. Tomcat server, Oracle DB, etc.) to make/install your custom extensions.
UPDATE (25.09.2015):
Currently Demandware are making extensions to their controllers, migrating from pipeleine-based controllers to script based ones. Chances are that at some point they may even introduce an API for creating web-services.
Until this happens, your only option is to make some custom pipelines and utilize something like XML/JSON over HTTP for this type of functionality. (Or if you insist on having it as SOAP based service, you would need to parse the SOAP envelopes with explicit code)
Demandware platform is a proprietary technology which allows developing only using their sandboxes and own IDE "UX Studio". All this stuff is available for demandware developers on their xchange portal. Access there could be requested by a merchant you do a development for.
Demandware has the core framework is closed to third parties and is exposed via the Demandware script and REST API's as well as Demandware's own Pipelet system.
Sadly you can't deploy external application in Demandware server, we have to separately create new app in UX studio
You can get the proper help on Demandware Wiki or on Exchange
