问题 I'm having trouble updating a C# application's product number. I updated the [assembly: AssemblyVersion("0.0.4.4")] and [assembly: AssemblyFileVersion("0.0.4.4")] in AssemblyInfo.cs. Then build a new MSI setup file. Then I proceed with uninstalling & installing the new version of the app. However, in Control Panel's Uninstall a program, my app keeps showing its product version as 0.4.3. Meanwhile, right-click & bring up properties of the app's EXE file shows the correct version number (4.4).

问题 We have a Till Software which also works with restaurants built on .NET (C#) and Firebird DB. We are having a strange problem recently, the items in an order are duplicating themselves when we go back to the order. Strangely it's not the case always. It's happening only sometimes. I tried to figure out under what conditions it's happening but it's so random that it doesn't happen for a couple of days and then start duplicating items for the next two days. The software is so huge that I don't

问题 I'm currently using a Hashtable wrapped as a Hashtable.Synchronized as a simple cache in a library that could be used by a multi-threaded environment (such as asp.net) - is this a suitable use for this collection? I understand that there are more suitable constructs available in .Net 4.0, but I'm stuck with .Net 3.5. If it makes any difference, this cache is read from frequently, and is written to very infrequently (but needs to remain threadsafe). Basic usage is something along the lines of:
