.net-3.5

问题 When I run my app targeted to .Net 3.5 it has massive memory leaks. 50mb every time I assign a UserControl to a local ref. I only ever create one instance of each UserControl. If I compile and run the same code targeted to .Net 4.0 everything runs fine hovering around the 50mb mark. Is this a known isue with 3.5? I.e. it's not usable in prod? /My clients only have 3.5 and won't be moving to 4.0 for awhile so i don't have the easy option 回答1: Memory Leak Hotfixes for WPF 3.5 SP1 http://www

问题 So it turns out that I am the last person to discover the fundamental floor that exists in Microsoft's Entity Framework when implementing TPT (Table Per Type) inheritance.

Now the time has come to add the other 20 sub types and OMG, I've just
