Support for .NET 4.6.2 +

[rmr964]

Since updating our solution to .NET 4.6.2, unable to send SMS using ClockWork. Getting the "Could not load file or assembly 'Clockwork,Version = 2.0.0.19839, Culture=neutral, PublicKeyToken=null; or one of it's dependencies. A strongly-name assembly is required

I suspect it's because ClockWork.dll is created with a lower version of .NET than 4.6.2
Is there a more elegant solution that having to download a copy , target as 4.6.2 and use that local version rather than the NUGET package?
