title: Can Application Insights be used with a Linux Web App running .NET Core 3 runtime?
body: <p>I am adding an Azure Application Service Plan to my resource group.  I'd like it to be a Linux Host for a .NET Core 3 Web API.  Furthermore, I'd like to use Application Insights.  However, when using the Azure Portal, the option to add Application Insights to a Linux .NET Core 3 application is greyed out.  Does Application Insights not currently support.  I have another Linux Web App that is using Node LTS as it's runtime and that allowed me to add Application Insights with no issue.  Is there something special I need to do to add Application Insights to a .NET Core 3 Web API running in an Azure Linux Web App?</p>
  
  <p>EDIT:
  Here are some screenshots of what I am seeing
