Clickonce .net upgrade
.net, .net-4.5, clickonce
Solution
If the user has only .NET 4 installed, they would need to install .NET 4.5 prior to installation.
Your ClickOnce application should have .NET as a prerequisite and prior to installing app, you can install .NET.

Problem
Microsoft.Net 4.5 is coming and I want to upgrade my clickonce app when MS releases the final version. My question is: Does the users who already have an clickonce application installed(with .net 4.0) will need to make a manual .net framework upgrade or it's going to be automaticly? Tks
