Cause

PipelineObjects.dll requires the Microsoft .NET Framework runtime activation policy to be used by the application calling it.

Resolution

Modify the app.config for the executable calling PipelineObjects to include the following <startup> element:

<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0" />
    </startup>
</configuration>

More information

PipelineObjects.dll is a tool that is provided with the BizTalk Software Development Kit (SDK) and is located in the SDK\Utilities\PipelineTools folder.

For more information about the <startup> element, see <startup> element.
