Bunch of cs utilities and usefull classes that anyone can use by just drag-in-drop The toolbox include:

Drop in extension compatible with Enumeration.Range, but with IList interface

• Exports IList interface (read only) in addition to IEnumerable
• All readers are 100% Thread safe
• All readers and seeker operations are O(1), even IndexOf and Contains
• Just use EnumerablePlus.RangeList instead of Enumerable.Range // drop-in replaceement

Add-on typed extension for our EnumerationPlus.RangeList that provides additional benefits:

• Defined for all integer types from sbyte to ulong
• All host type range support for Start parameter (but Count naturally restricted to Int32 by IList itself)
• Suports RangeAsList(T Count) additional maker factory function to provide 0..Count-1 elements

Added function call argument-less clouse abstraction with parameters available externally. Use this class to encasulate closured function call : the function and its arguments ready to call. This allow to examine parameters before apply the call (and use them as a source for, say caching key generation) The call is "suspended" until really need to call.

var MyCall = FuncCall.Create((a, b, c) => { return a + b + c+ 1; }, 1, 2, 3)

That is, you may use MyCall.Func<ResultType> to check function properties and MyCall.Args as arguments given before the call. If source function does not take any arguments, content of Args is implemenation-defined, else it will be a tuple filled with arguments. You may use MyCall.Invoke() to do actual invocation. This would open way to efficient and simple ccing of function calls. Alternatively, you may use FuncCall.Call() to obtain FuncCallResult<ResultType> object that acts alike Task object with Result and Exception properties.
