Question:
I have an application program that was build referencing previous version of CHILKATDOTNET2.DLL Recently, I have downloaded the newer version of CHILKATDOTNET2.DLL and placed in same the folder of the application program. When I execute the application the got the following error:
Could not load file or assembly ‘ChilkatDotNet2, Version=8.3.0.0, Culture=neutral, PublicKeyToken=eb5fc1fc52ef09bd’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0×80131040)
On the other hand, if I rebuilt the application program referencing the new version of CHILKATDOTNET2.DLL, but run the program with the older version of CHILKATDOTNET2.DLL, I also got similar error.
My question is: is the difference version of CHILKATDOTNET2.DLL not backward/forward compatible? My concern is that I have more than one applications using CHILKATDOTNET2.DLL, if for some reason I need to upgrade the server machine with the new version of CHILKATDOTNET2.DLL, it seemed that the applications using it will start to fail.
Answer:
The .NET runtime enforces the condition that the version of the assembly loaded at runtime must match the version of the assembly used at compile time.
