title: Integrate Azure Key Vault with ASP.NET 4.0
body: <p>We have asp.net 4.0 application which is now going to deployed to Azure. A look ahead environment with IIS and SQL managed instance has been provided. We have been asked to move the database connection details to Azure Key Vault. Tried searching the internet but got references for mostly .net core applications. Upgrading the .net framework is not an option. So far we have registered an application in Azure Active Directory and got the tenant id, client id, client secret. This application has been added in Access policies with all the permissions. Also the secret key with connection string value has been created. Now the challenge is how to access this key vault secret in our asp.net 4.0 application. Thanks</p>
