We have our own glue-layer-code-thingamajig that allows us to host the .NET runtime in our Win32 Delphi program. This has allowed us to do a gradual transition to .NET over time.

We already use VS2008, and C# 3.0, while still targeting .NET 2.0 framework runtime. Now the problem occurs when we want to upgrade our NAnt scripts, to compile ...
For parameters to an OperationContract that represent a date only (no time component or timezone designator), it is desirable to use xs:Date, to avoid any ambiguity or problems with timezone conversion between client and server.
