The xref:System.AppDomainSetup.TargetFrameworkName?displayProperty=fullName was previously null in the default app domain, unless it was explicitly set. Beginning in 4.6, the xref:System.AppDomainSetup.TargetFrameworkName?displayProperty=fullName property for the default app domain will have a default value derived from the TargetFrameworkAttribute (if one is present). Non-default app domains will continue to inherit their xref:System.AppDomainSetup.TargetFrameworkName?displayProperty=fullName from the default app domain (which will not default to null in 4.6) unless it is explicitly overridden.
Code should be updated to not depend on xref:System.AppDomainSetup.TargetFrameworkName defaulting to null. If it is required that this property continue to evaluate to null, it can be explicitly set to that value.
