The other day I spent way more time trying to figure out why I couldn’t run Todo App locally than I really wanted to have. The main thing that was driving me nuts was that it worked fine the day before. The good news is that I figured out my issue which let me to write this post on how to enable SSL in ASP.NET Web API applications.
Enabling SSL for any web application that requires a login is important to keep data encrypted. For development we are just going to to use a self signed cert, but if you are using Azure to deploy your web app it will automatically use Azure’s cert if you are on a sub-domain.
Turn on SSL
To Enable SSL left click on your Project in Visual Studio and the properties
window should open up at the bottom right. Inside of the SSL Enabled row toggle
the value to
True. Right below there should be another row called SSL URL
which should have a value something like:
Force HTTPS for the entire app
Rather than adding an attribute to every single controller in our web app we can apply a global filture that will require https to be used.
Inside of the
App_Start folder open up the
FilterConfig.cs file and add the
following line to the existing method:
Set the project Url
Just to double check since this was the problem I was having you need to make sure the project URL is using the new https url and not the old http url. To change the project URL right-click on your project and select Properties from the bottom of the dropdown. This should open up a section with a bunch of tabs down the left column. Select the ‘Web’ tab and under the ‘Servers’ section make sure the ‘Project Url’ is set to:
Now when you press the green play button to debug (F5) your selected browser should open up with the new url.
