Changing the target runtime version of Azure Functions


Azure Functions 2.x runtime is based on .NET Core 2 from .NET Framework 4.7 in 1.x. So, any application migrating from 1.x to 2.x needs to make sure that they are using and referring the compatible code and libraries.

We can also update our Azure Functions to target the appropriate runtime using the below steps à

Inside Azure Portal, select the Function App, click on Application Settings within Platform Features tab.

We can specify the version number for the APP SETTING NAME – FUNCTIONS_EXTENSION_VERSION

Fixed – Publish as Azure Web Job Option missing in Visual Studio 2017


While trying to publish one of our console application to Azure as Web Job we couldn’t find the “Publish as Azure WebJob..” option

It was because Azure development tools were recently uninstalled from the system.

To install it, go to Windows à Program and Features à Select Visual Studio 2017 and click on Modify.

And select Azure Development for installation

Select Azure Cloud Services tool.

After installation it will ask for restart.

After restart we’d see the option added in our Visual Studio.

Hope it helps.

After much struggle, in one of threads there was a suggestion to try in a different browser or in private browsing mode. And luckily that worked.

Out of all responses, this one makes the most sense for this issue
