The assemblies Microsoft.Threading.Tasks and Microsoft.Threading.Tasks.Extensions are still referencing v1.5.11.0 of System.Runtime and System.Threading.Tasks. Without the bindingRedirect, the Microsoft.* assemblies would try to load an old version of the System.* assemblies, which would fail.
Indeed, it is for performance reasons. The BCL team did a lot of research on this point before deciding to go with what you rightly call out as a suspicious and dangerous practice: the use of a mutable value type. You ask why this doesn’t cause boxing. It’s because the C# compiler does not generate … Read more
I can only tell how the Mono Project does this. The theorem is quite simple, though it gives a code mess. They first compile System.Configuration.dll, without the part needing the reference to System.Xml.dll. After this, they compile System.Xml.dll the normal way. Now comes the magic. They recompile System.configuration.dll, with the part needing the reference to … Read more
I would call Directory.CreateDirectory(@”C:\dir0\dir1\dir2\dir3\dir4\”). Contrary to popular belief, Directory.CreateDirectory will automatically create whichever parent directories do not exist. In MSDN’s words, Creates all directories and subdirectories as specified by path. If the entire path already exists, it will do nothing. (It won’t throw an exception)
There’s no such thing as an empty char. The closest you can get is ‘\0′, the Unicode “null” character. Given that you can embed that within string literals or express it on its own very easily, why would you want a separate field for it? Equally, the “it’s easy to confuse “” and ” “” … Read more
Tuples are available since .NET4.0 and support generics: Tuple<string, int> t = new Tuple<string, int>(“Hello”, 4); In previous versions you can use System.Collections.Generic.KeyValuePair<K, V> or a solution like the following: public class Pair<T, U> { public Pair() { } public Pair(T first, U second) { this.First = first; this.Second = second; } public T First … Read more
