I have created an abstract class in my report library that inherits from Telerik.Reporting.Report. When I try to load the project's assembly in the Standalone Report Designer to import those reports as TRDP, an exception is thrown while the application tries to load the assembly that there are report types that do not have a parameterless constructor.

To resolve the issue, I had to remove the 'abstract' modifier. However, that should not be necessary. The wizard should ignore abstract classes or at the very least, let me import the other report types while displaying a message that there are report types with parameterless constructors.
