I have Chilkat's 64 bit DLL within a .NET 4.5 project. But when I try to build I get: The type or namespace name 'Chilkat' could not be found (are you missing a using directive or an assembly reference?)
It works absolutely fine if I run the application with IIS on the same machine.
Alternatively to allow Visual Studio to build I have to add the 32 Bit reference. But then I have to change my app pool to allow 32 bit applications.
How can I get Visual Studio to build with the 64 bit DLL?
