For the most part, you can ignore this detail. But if you look through the specification, you'll see various place that the language considers conversions from type X to type Y. There are other places that the language considers... more

Yes, it's easy to deadlock, without actually accessing any data: private readonly object lock1 = new object(); private readonly object lock2 = new object(); public void Method1() { lock(lock1) { Thread.Sleep(1000); ... more

So my question is: how to declare it? You can't. All arrays in .NET are fixed size: you can't create an array instance without knowing the size. It looks to me like you should have a List<T> - and I'd actually create a class... more

This is the problem: string _plantCode = appSettings["PlantCode"] ?? "Not Found"; That isn't assigning to the instance variable - it's declaring a new local variable. You just want: _plantCode = appSettings["PlantCode"] ?? "Not... more

You're probably using the 32-bit CLR in one test runner and the 64-bit CLR in another. The implementation of string.GetHashCode differs between the two. You should not depend on them being consistent between runs - they only have to be... more

How do I iterate over the loc values? The simplest way is to use the overload of Descendants which accepts an XName: foreach (var loc in siteMap.Descendants("loc")) { string value = loc.Value; ... } Currently, you're asking... more
