This post is about how to deploy ASP.NET Core preview versions in Azure app service.
In this post I am deploying an ASP.NET Core 2.2 Preview Web API to Azure web app. You can deploy the ASP.NET Core preview versions using following three approaches.
You can install the Azure Web App extension for ASP.NET Core preview. From the Azure web app overview, search for extensions.
Click on the
Add button, from the
Add Extension blade, select the
choose extension menu. And select the ASP.NET Core runtime - based on the Web App platform. Since I am using free plan, I am selecting
ASP.NET Core 2.2 (x86) Runtime.
Next click on the
Accept legal terms. Once it is done, you can click Ok, this will install the ASP.NET Core extension in Azure web app.
Once it is installed you can publish the app from visual studio using the Publish wizard.
If you don’t want to enable ASP.NET Core extension, other option is publishing the app as
Self Contained. In Visual Studio, you can configure it in the Publish Wizard, select Settings, and choose Deployment Mode as Self contained.
If you’re not using Visual Studio, you’re using VS Code or CLI, you can modify the CSProj file and include
<RuntimeIdentifier> and specify
win-x86 there. And you can publish using
dotnet publish command or you can directly publish using
dotnet publish --configuration Release --runtime win-x86 command. Once the publish finished, upload the files from
The Docker Hub contains the latest preview Docker images. The images can be used as a base image. Use the image and deploy to Web Apps for Containers normally.
Using the above methods you can deploy apps built on top of preview versions of .NET Core. In the above mentioned methods, which one is good? Depends on your app and features. I prefer the extension method, other two requires some additional steps in the development or build process.
Happy Programming :)
