NetEvolve.Guard

This library provides a set of guard clauses to validate method parameters and object states in a fluent manner. For this purpose, the library provides the Ensure-class, which is a static class with a set of extension methods. The usage is very simple and intuitive. The following example shows the basic usage of the Ensure-class.

public static bool Execute(string? directoryFolder)
{
    string directory = Ensure.That(directoryFolder).IsNotNullOrWhiteSpace();
    // or alternatively
    string directory = Ensure.That(directoryFolder, nameof(directoryFolder)).IsNotNullOrWhiteSpace();

    // Do some magic
    ...
}

As you can see, the second parameter parameterName is optional and is automatically populated by .NET, based on the CallerArgumentExpressionAttribute functionality. This reduces the amount of code you have to write and makes the code more readable.
