No workaround required. You can't.  .NET Framework need Vista SP 2 or higher.

So where .NET 4.5.1 is required, you need an operating system that is not dead.

Sorry, but XP is being dropped by Microsoft and Vendors at every turn now.

It appears not.

EE frowns on links from competitive sites but this reference below appears to be the best reference out there for trying what you want to do.


Note the suggestion to use Mono to install 4.5 for compatibility.  I've looked at the Mono site but can't determine if it will install for you.  Or if it would even supply the compatibility you require if it did.  Mono is missing full 4.5 functionality.  There appear to be calls in 4.5 to Windows API functions that don't exist in Windows XP which is why it isn't supported and if your application calls those you are out of luck.
