| Use of static methods (4 replies, VIP) |
| microsoft.public.dotnet.framework.component_services |
| Hi, I was wondering if I can use static methods in a class that derives from the ServicedComponent. The expected callers of my class will be only other .NET clients and the static methods require COM services such as support for automatic transactions. What are the restrictions or recommendations for coding ServicedComponent derived classes? Thanks, Ohad Ohad Young Medical Informatics Research Cen... |
