Connecting to a MySQL database is fairly simple and straight forward. The first thing you will need to do is to add a reference to MySQL.Data in your project.

This can be done in a few ways:

  • Right click on references in your project -> click Manage NuGet packages -> Search and install MySQL.Data from Oracle
  • Open Package Manager Console from Tools -> NuGet Package Manager -> Paste in the console the following line: Install-Package MySql.Data
  • If you have installed the .NET Connector from MySQL you can navigate to where you have installed the connector and add a reference to the MySQL.Data.dll file

After you have added a reference to MySQL.Data you can tailor the snippet below to suit your requirements.

Xamarin is now included for free in Visual Studio

Starting April of 2016, Visual Studio now includes Xamarin for free. This is the case for every edition of Visual Studio, including Visual Studio Community Edition, which is free as well.

With Xamarin you can develop and publish native apps for iOS and Android using C# or F# from directly within Visual Studio with no limits on app size.

For developers that are using Mac, Xamarin Studio is now available as a benefit of your Visual Studio Professional or Enterprise subscription. Developers can use the newly-created Xamarin Studio Community Edition for free.

You can visit Xamarin’s store to download Xamarin for free. Keep in mind that, Xamarin, although free, is license restricted for bigger companies. If you want to use Xamarin you will need to comply to one of the following license terms:

  • Individual license – If you are an individual working on your own applications to sell or for any other purpose, you may use the software to develop and test those applications.
  • Organization licenses – If you are an organization, your users may use the software as follows:
    • Any number of your users may use the software to develop and test your applications released under Open Source Initiative (OSI) approved open source software licenses.
    • Any number of your users may use the software to develop and test extensions to Visual Studio.
    • Any number of your users may use the software to develop and test your applications as part of online or in person classroom training and education, or for performing academic research.
    • If none of the above apply, and you are also not an enterprise (defined below), then up to 5 of your individual users can use the software concurrently to develop and test your applications.
    • If you are an enterprise, your employees and contractors may not use the software to develop or test your applications, except for open source and education purposes as permitted above. An enterprise is any organization and its affiliates who collectively have either (a) more than 250 PCs or users or (b) more than one million US dollars (or the equivalent in other currencies) in annual revenues, and enterprise means those entities that control (via majority ownership), are controlled by, or are under common control with an organization.
  • Demo use – The uses permitted above include use of the software in demonstrating your applications.

Force HTTPS using IIS

Google announced in their blog that it will start favoring websites that use HTTPS. Google ranking and increased security for your users is two major reasons why you should consider getting an SSL certificate and moving your website to HTTPS.

If you are using IIS you can use the below snippet in your web.config in order to redirect all HTTP requests to HTTPS.

For your convenience, in case you are not familiar how to use the snippet below, I have attached an image to illustrate how the rewrite rule will look using IIS’s interface, so if you are having trouble with the web.config, simply mirror the details in the image.

Please keep in mind that to use the snippet below you will need to have URL Rewrite module installed and enabled.
