TLS 1.2 Upgrade in Azure Redis Cache Server

Introduction

 
The TLS 1.0 and 1.1. support will be retired soon in the Azure Redis cache server. It is required to do some configuration setting updates in the code as long as the ASP.NET application is using an Azure cache server with a .NET framework lower than 4.6. In this blog, you will learn how to do the configuration setting updates in an ASP.NET Application with .NET Framework 4.2, so that it will support TLS1.2 in the Azure Redis cache server.
