Read a couple of stickies and threads, .NET still a no go?

You can freely use our tools to package your app and release it to your users today. It just doesn't have checks to ensure that a specific version of .NET is present.

We'll be shortly releasing what I've termed "Universal .NET apps". These are .NET apps that are built with .NET 2 but have been tested with and a manifest that specifies they will work with 2, 3.5 and 4. These apps will work out of the box on Windows Vista through 10 and even on XP if you install any version of .NET.

Your app requires .NET 4.5 which is a little trickier. .NET 4 and later is only included with Windows 8 and 10. Windows 7 and Vista users require an admin to manually download and install .NET 4/4.5. For apps to be released as "portable" here they must work with at least Windows 7 and up without anything installed or changed on the local machine so they work out of the box on the vast majority of Windows machines.

We'll also be adding a .NET-specific section of our directory in the future for apps that require a specific .NET version that isn't preinstalled and enabled on Windows 7/8/10.
