We have a wsdl specifying a datetime element. It is nullable, in the sense that minOccurs=0. However, using svcutil to generate a proxy class does not give us a .net nullable DateTime property, so how best can we make the proxy class serialise the message to a SOAP message that does not contain the datetime element? ...

Hi All, How do I achieve the equivalent of the LVIS_CUT style for a listview item? It looks like it's not exposed by the framework? Should I P/Invoke? Edit: LVIS_CUT is a Win32 style that affects the look of the item: It grays the item image. You can see it in action in Windows Explorer: Select a file and type Ctrl+X. TIA. ...

I was close to implement a kind of Composite(D...

I have an assembly that is targeted for .NET 3.5. I have an application targeted for .NET 2.0 and wonder if I should have any trouble referencing the 3.5 assembly from the 2.0 application.
