The located assembly's manifest definition does not match the assembly reference

hi all,
We have an c# dotnet application which has common functionalites, testadapter.dll is the dll built for this . As testadapter.dll contains common functionalities we use this dll in other modules also. We dont use GAC and we will deploy this testadapter.dll in visual studio/bin and we will run other modules . Recently testadapter.dll is upgraded to 13.1.1.2 and when we deployed this in other modules and ran it from visual studio we are facing below exception

Could not load file or assembly 'testadapter, Version=13.1.1.1, Culture=neutral, PublicKeyToken=e48a2ba1dd04eb1f' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

Any info on this will be very helpful to us

Thanks,

Suresh
