Azure DevOps deployment output
You might want to change the naming of the extension to: “AspNetCoreRuntime.3.0.x64”, it seems like the extension served by Microsoft is not in the library under it’s original naming “AspNetCoreRuntime” any longer.
“resources”: [
{
“type”: “siteextensions”,
“name”: “AspNetCoreRuntime.3.0.x64”,
“apiVersion”: “[variables(‘siteExtensionsVersion’)]”,
“location”: “[resourceGroup().location]”,
“properties”: {
},
“dependsOn”: [
“[resourceId(‘Microsoft.Web/sites’, variables(‘siWebAppNameTidy’))]”
]
}
]
Hope this saves you some time troubleshooting.
