I've found the exception below
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileLoadException: Could not load file or assembly 'Infragistics4.Win.UltraWinGrid.v13.1, Version=13.1.20131.2060, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
I've already copied the dll into the working folder, but still not working. Any clue how to resolve it?
Thanks
Hello Kevin,
Usually exceptions of the kind “Could not load file or assembly …” are caused when you have upgraded Infragistics reference manually and you have forgotten to set their Specific version to false, clean the content of licenses.licx file from all Infragistics entries, clean and rebuild your solution. So please try this suggestion and if it doesn’t works for you, please let me know when exactly this exception occured for the first time (what have you done with your solution before it happens for first time)? Are you using any custom assembly which internally refers Infragistics assembly?
I am waiting for your response.
I have tried your suggestions, but still doesn't work. I was using trial version and it worked. After I've entered the product key and upgraded the components I started seeing this exception. I agree with you that must be something related to the upgrade. Could you please advise how should I tackle this. Thanks
