Build Warning common

[Curt_C]

Hi,

I get this warning when I build my project (VB/VS 2005/MS for 2005).

No way to resolve conflict between "NationalInstruments.Common.Native, Version=8.1.20.415, Culture=neutral, PublicKeyToken=4544464cdeaab541" and "NationalInstruments.Common.Native, Version=8.1.20.165, Culture=neutral, PublicKeyToken=4544464cdeaab541". Choosing "NationalInstruments.Common.Native, Version=8.1.20.415, Culture=neutral, PublicKeyToken=4544464cdeaab541" arbitrarily.

No way to resolve conflict between "NationalInstruments.Common, Version=8.1.20.168, Culture=neutral, PublicKeyToken=4544464cdeaab541" and "NationalInstruments.Common, Version=8.1.20.165, Culture=neutral, PublicKeyToken=4544464cdeaab541". Choosing "NationalInstruments.Common, Version=8.1.20.168, Culture=neutral, PublicKeyToken=4544464cdeaab541" arbitrarily.

Consider app.config remapping of assembly "NationalInstruments.Common.Native, Culture=neutral, PublicKeyToken=4544464cdeaab541" from Version "8.1.20.165" [C:\WINDOWS\assembly\GAC_32\NationalInstruments.Common.Native\8.1.20.165__4544464cdeaab541\NationalInstruments.Common.Native.dll] to Version "8.1.20.415" [C:\Program Files\National Instruments\MeasurementStudioVS2005\DotNET\Assemblies\Current\NationalInstruments.Common.Native.dll] to solve conflict and get rid of warning.

Consider app.config remapping of assembly "NationalInstruments.Common, Culture=neutral, PublicKeyToken=4544464cdeaab541" from Version "8.1.20.168" [] to Version "8.1.20.415" [C:\Program Files\National Instruments\MeasurementStudioVS2005\DotNET\Assemblies\Current\NationalInstruments.Common.dll] to solve conflict and get rid of warning.

I have references to the following NET libraries in my project

NationalInstruments.Analysis.Enterprise

.Common

.DAQmx

.Net

.UI

.UI.WindowsForms

.VisaNS

All of the references are to files located at

C:\Program Files\National Instruments\MeasurementStudioVS2005\DotNET\Assemblies\Current

Is there a conflict? Does anyone know what's going on?

Also, I don't have any explicit reference to the Common.Native library. 

The app builds and runs ok.  I'd just like to clean up the warnings before a final release

Thanks

Curt

You can safely ignore these warnings. Sadly, they are expected, as documented in KB 3UQHBA00.

You can add entries to your app.config file to eliminate the warnings, but this has a side effect. The side effect is if in the future your application needs to reference (directly or indirectly) a newer version of Common, you'll have to update the entries in the app.config file. For example, you might indirectly need to reference a newer version of Common if you update to a newer version of NI-DAQmx.

The issue here is that Microsoft decided that it would be best to warn you if your application references two different versions of the same assembly, even when there is a policy file (as in the case of NationalInstruments.Common) that resolves the difference for you. This warning was introduced in Visual Studio 2005. I believe that the Microsoft perspective is that they can't accurately determine, at build time, if a policy file will exist at run time to resolve the difference. I think it is unfortunate that there is no good way to disable this warning if you happen to know that a policy file exists.
