I have an ASP.NET Core 8 Web API, and it needs to reach an Azure SQL managed instance that exists in other resource group.
I already peered the virtual network of the managed instance with my web app virtual network.
I already created the inbound and outbound security rules on my network security group
On my web app I am using the default dns feature.
There is no firewall configured in the managed instance virtual network. The same in the web app virtual network.
When I debug the web app using visual studio I catch a timeout exception after the managed instance was not found.
If I run my web app from Visual Studio, I can reach the managed instance without problem.
I want to connect my Azure web app to my Azure SQL managed instance.
After adding the environment variable WEBSITE_VNET_ROUTE_ALL to my webapp as the article https://learn.microsoft.com/en-us/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet#networking. I was able to reached my managed instance
