Hello Support.  My environment currently has clients running Bartender 9.1 and am upgrading to 10.0 SR4.  My understanding based on other posts is that if I compile my program using the oldest version (9.1), I should be able to use that same program across the future versions of Bartender as well.  The application is .NET and I have it compiling using .NET 3.5.  If I run the application at 9.1, it works fine.  If I open with a 10.0 SR4, I receive the error:  Could not load file or assembly "Seagull.BarTender.Print, Version 9.1.0.0, Culture=neutral, PublicKeyToken=null" or one of its dependencies.  The located assembly's manifest definition does not match the assembly reference. (Exceptiono from HRESULT: 0x80131040)

I know that 9.1 is ending support July 1st and we are moving to update the legacy clients; however, due to the environment (validated), I don't have the ability to update all of them in the near future.  I am compiling at x86, not 64-bit.  I'm excluding the files when packaging.  I've selected "Specific Version = False" for your DLL reference.  I'm specifying .NET 3.5 and running Visual Studio 2012.  If I just compile the program over the 10.0 SR4 SDK DLL, it works fine on the 10.0 SR4 clients. 

I would like to avoid having two copies of my program to utilize the appropriate SDK.  I have workstations running Windows XP, 7, 8.1. 

Thanks in advance for your assistance.

Sincerely,

Walt
