title: Bicep - How to config Runtime Stack to Azure App Service (Bicep version 0.4)
body: <p>I was able to create an App Service Plan and App Service using the latest Bicep Version 0.4.</p>
  <pre><code>resource myAppServicePlan 'Microsoft.Web/serverfarms@2021-01-01'={
  name: AppServicePlanName
  location: Location
  sku: {
   name: appServicePlanSkuName
   tier: AppServiceTier
   }  
  }
  resource myAppService 'Microsoft.Web/sites@2021-01-01'={
    name: AppServiceName
    location: Location
    properties:{
    serverFarmId: myAppServicePlan.id
    }
   }
  </code></pre>
  <p>Be default, it takes ASP.NET 4.8 as the framework version. I would like to use the Framework as Netcore 3.1. is there a way to achieve it yet?</p>
  <p>Please suggest.
  Thank you.
