Auto upgrading .NET framework

Question

My distributed App is using .NET 4.6 features. It's not installed via ClickOnce, but installed manually, for certain reasons. How can I check if installed .NET is lower version and update it before running app. My users are not advanced people and I can't send .NET upgrade instructions to them.

Answer 1

Use some of the resources below.

After determining the version you have installed, you will probably want your "code" to deploy .NET using the "Custom Setup (chaining)" method...you can decide if you want it to be silent, show the .NET frameworks' installation UI, or use your own custom one.
