Could not load file or assembly 'System.ValueTuple'

Question

I\'ve got a VS2017 project that compiles to a DLL which is then called by an EXE written by someone else. Both projects target .Net Framework 4.6.2. I rewrote one of my DLL

Answer 1

I resolved this issue by registering System.ValueTuple in my computer's machine.config file (along with my own DLL which was already registered there). I don't particularly like this approach though since it's dependent upon the DLL version which is subject to change at any time. Hopefully MS will just add this assembly to the next version of the .Net Framework.
