| microsoft.public.dotnet.framework.performance |
| Hi, I ngen'd an assembly, but I observed that the native image gets invalid if the system time of the machine is not correct (e.g. the bios battery is empty). I didn't find any indication on the msdn site that time is an issue for an native image to get invalid. Has anybody more information on this behavior? Is there a way to prevent it (workaround)?

| I have been having problems with RAM usage when finding LDAP nodes. In a lot of cases my code does a search that fails to find any nodes. Looking at the FindOne() code in "Reflector", I see that Dispose() is only called on the SearchResultCollection, if a node is found. Can someone in the ADSI teem look at this? For now I can use Find() as a workaround. public SearchResult FindOne() { SearchResult... |
