  <p>I have used this <a href="https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/function_app" rel="nofollow noreferrer">https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/function_app</a> for creating terraform code, by using the above document and other reference in google, i have written the below code in main.tf</p>
  <pre><code>app_settings = {
          FUNCTIONS_WORKER_RUNTIME = var.FUNCTIONS_WORKER_RUNTIME
          FUNCTIONS_WORKER_RUNTIME_VERSION = var.FUNCTIONS_WORKER_RUNTIME_VERSION
  </code></pre>
  <p>Assigned the variable in variable.tf as below</p>
  <pre><code>variable &quot;FUNCTIONS_WORKER_RUNTIME&quot;{
      default = &quot;PowerShell&quot; 
  }
  
  variable &quot;FUNCTIONS_WORKER_RUNTIME_VERSION&quot; {
      default = &quot;~7&quot;
  }
  </code></pre>
  <p>But still could not able to see PowerShell Core Version in the app.</p>
