4.7
NotPlanned
In the .NET Framework 4.6.2 and earlier versions, when the Execute method of a
workflow activity throws an exception with a null
value for the
xref:System.Exception.Message property, the
System.Activities Workflow runtime throws a
xref:System.NullReferenceException?displayProperty=name, masking the original
exception.
In the .NET Framework 4.7, the previously masked exception is thrown.
- Quirked
- Build-time break
If your code relies on handling the xref:System.NullReferenceException?displayProperty=name, change it to catch the exceptions that could be thrown from your custom activities.
