C# Класс SimpleHelpers.NamedLock

Synchronization helper: a static lock collection associated with a key. NamedLock manages the lifetime of critical sections that can be accessed by a key (name) throughout the application. It also have some helper methods to allow a maximum wait time (timeout) to aquire the lock and safelly release it. Note: this nuget package contains c# source code and depends on System.Collections.Concurrent introduced in .Net 4.0.
