Using 2 different versions of the same dll?
问题 I have been given 2 pre-compiled dlls: Common.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f3b12eb6de839f43, processorArchitecture=MSIL Common.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=f3b12eb6de839f43, processorArchitecture=MSIL Example of differences in API: And I'm trying to load both into a single project to do something like this: extern alias v10; extern alias v20; private static void UpgradeUser() { // Load old user var userOld = new v10::Common.Data.UserData();
