Through this project of six sections, you will learn how Microsoft Visual Studio .NET Enterprise Architect Edition can be used to design, create, deploy, and maintain enterprise-strength distributed applications

Web Payments is an emerging web standard being developed by the W3C to simplify online payments and enable a broader set of players to participate easily in the payments ecosystem on the web. The standards are flexible; they work with various types of payment systems and are intended to work on any browser on any device, payment method, or payment service provider. This flexibility enables development simplicity, deployment consistency, and future compatibility with emerging payment technologies.

Here are some of the reasons why nullable reference types are less than ideal:

• Invoking a member on a null value will issue a System.NullReferenceException exception, and every invocation that results in a System.NullReferenceException in production code is a bug. Unfortunately, however, with nullable reference types we “fall in” to doing the wrong thing rather than the right thing. The “fall in” action is to invoke a reference type without checking for null.
• There’s an inconsistency between reference types and value types (following the introduction of Nullable<T>) in that value types are nullable when decorated with  “?” (for example, int? number); otherwise, they default to non-nullable. In contrast, reference types are nullable by default. This is “normal” to those of us who have been programming in C# for a long time, but if we could do it all over, we’d want the default for reference types to be non-nullable and the addition of a “?” to be an explicit way to allow nulls.
• It’s not possible to run static flow analysis to check all paths regarding whether a value will be null before dereferencing it, or not. Consider, for example, if there were unmanaged code invocations, multi-threading, or null assignment/­replacement based on runtime conditions. (Not to mention whether analysis would include checking of all library APIs that are invoked.)
• There’s no reasonable syntax to indicate that a reference type value of null is invalid for a particular declaration.
• There’s no way to decorate parameters to not allow null.
