I have watched this tutorial on setting up offline sync for a Xamarin application using an Azure backend. I have a MySQL table on my Azure portal and I now wish to add the back-end calls to sync my local SQLite database with the MySQL cloud database.
I am not using the Easy Tables software used in the tutorial above, and I would like to use C# for the backend calls for my MobileServiceClient to talk to, where it calls methods such as:
await client.SyncContext.PushAsync();
await table.PullAsync("alltable", table.CreateQuery());
await table.InsertAsync(entry);
What are the steps to setting up the cloud syncing functionality from my SQLite store to my MySQL database?
Unfortunately MySQL is not compatible with Azure's IMobileServiceClient, you must change to using Azure SQL to use the inbuilt functions in IMobileServiceClient

Good day, I am trying to backup a Microsoft Azure SQL database using an ASP.Net application programmatically into either a .BACPAC file I can download to a local machine or into an Azure blob storage platform. I know similar questions have been asked before but I have searched the web and cannot find a recent solution that seems to work. A simple "Backup database" SQL query also doesn't seem to be possible as I am constantly thrown with the error message: 'BACKUP DATABASE' is not supported in this version of SQL Server. Any help would be greatly appreciated. Attempt at consuming API
The simplest way i think is to use Databases - Export Rest Api(Exports a database to a bacpac)
The rest api provides you with a blobUri which you can use to download or transfer to Azure blob storage
I am trying to connect an Azure SQL DB resource using the app id of an already registered application in Azure.
I am using entity framework database first approach.
Since you have an c# Azure web APP, please reference this document: Quickstart: Use .NET Core (C#) to query an Azure SQL database.
In this quickstart, you'll use .NET Core and C# code to connect to an Azure SQL database. You'll then run a Transact-SQL statement to query data.
Hope this helps.
There are a few steps to connecting to the Azure SQL database. I suggest reading this article
You will need to:
Add your IP to the Azure SQL firewall
Create a login via SQL management studio
Once you've completed the above you'll be able to update the connection string in your application's web.config to establish a connection.
I am having trouble connecting my Azure database to an existing Xamarin forms project. I have followed all the steps to make the database accessible but don't understand how to connect it to the project.
I would be grateful for any help.
As CSharpRocks mentioned that Azure Mobile App would be an ideal approach for you to build your mobile backend with Azure sql database, then you could leverage the client SDK for Azure Mobile Apps in your Xamarin.Forms project to communicate with your Azure sql database.
You could follow the steps below for getting started with Azure Mobile Apps with Xamarin.Forms app:
Create your Mobile App and configure the server project, for more details you could refer to here.
Note: For Node.js backend, you could navigate to "Mobile > Easy tables" for adding new or existing tables, then it would automatically create the Node.js backend (table API) for your added table(s). For C# backend, you could download the sample server project from quickstart or create the Azure Mobile App template via VS and implement table controllers for each of your tables, for more details you could refer to adrian hall's book about Implementing Table Controllers.
For your mobile client, you could download and run the Xamarin.Forms project from quickstart to getting started with client SDK for Azure Mobile Apps. Also, you could refer to adrian hall's book about Chapter 3 - Data Access and Offline Sync > The Mobile Client.
Additionally, you could add authentication to your Xamarin.Forms app and only the authenticated and authorized users could access the table data under your Mobile App. For more details, you could refer to here.
I am using azure mobile service which has a sql database. I would like to get a connection between my windows phone app and azure mobile service sql database. How can I achieve it?
In TodoItem example, there is no any table information that data will be taken.
P.S. : Googled a lot but nothing satisfied even azure documentation. TodoItem example does not show some details. For example my database table name is Scores where code line should I edit in TodoItem example?
You can download TodoItem example here.
in Azure Mobile Service, you don't access the database directly from your mobile application. you talk to the Mobile Service backend which in turn talks to your database.
as #hSchroedl mentioned, you should use the Mobile Service API to access your database tables.
You can easily follow the TodoItem sample to create representations of your own tables.
If your question is how do I get my Azure Mobile services database connection string, then the answer is: look in the Azure portal -> your Mobile Services name -> Dashboard tab -> Click on your database name. There you have your database connection string.
You can use this connection string in Visual Studio to connect to your Mobile Services database but can't be used directly in your mobile app.
Note: You can't access your database directly from your mobile app without using the Azure Mobile Services APIs.
Take a moment and review the Azure Mobile services documentation and tutorials to get a better understanding of it works.
Hope this helps
Is it possible to create a Azure SQL database table employing code written within Visual Studio?
I have made attempts by creating an API on my mobile service and then calling that but each time I run into permission failures.
If I create the table directly from within Azure then my CRUD code works fine. However I need to provide users with the ability to create tables without them having to access Azure accounts.
I think you should try DbInitializer and Migrations in your .NET backend of Windows Azure Mobile Service.
In the attached link described how it works.
