Overridden members (that include an ‘override‘ keyword) provide a new implementation of a virtual or an abstract member with the same signature. Compile-time errors occur when member override rules are violated. To declare an overridden member according to the language specification without violating its rules, CodeRush suggests several overridden-specific code issues.
In addition to CodeRush code issues for virtual members, there are similar code issues for abstract members. An abstract member is similar to a virtual member but with no implementation, in other words, it has no body. In contrast to virtual members, abstract members must be implemented in a derived class if one is inherited from the class that contains an abstract member.
As you probably know, if a member is declared with the ‘virtual‘ keyword, derived classes can override the implementation of this member. In a virtual member invocation, the run-time type of the instance for which that invocation takes place determines the actual member implementation to invoke: whether it is a base virtual member or an overridden member from a derived class. The virtual member is declared like an instance member with addition of a ‘virtual‘ keyword to its declaration.
The consume-first declaration features of CodeRush are a quick way to generate the required code without typing the entire declaration’s code by hand. Once you have a reference to an undeclared member, pressing the CodeRush key allows you to choose a member you would like to declare. Let’s take a look at the property-declaring code generation providers you can use.
The Expression Lab is a DXCore diagnostic plug-in containing the tool window that displays the hierarchical abstract source tree built by the DXCore. This is useful to learn the structure of the parsed source code and created a source tree to build your own DXCore plug-ins. When you know the structure of the tree, you can build your own trees or its parts and generate the appropriate code for all programming languages supported by the DXCore. Also, you can see the set of properties each language element has, to learn more on how to construct any specific elements.
The CodeRush Unit Test Runner supports running tests from the Silverlight Unit Test Framework which is a part of Silverlight Toolkit now, so it’s easy to test your Silverlight applications.
Once you install the Silverlight Unit Test Framework, you are able to create the Silverlight Unit Test Application project. Here is what the Add Project dialog looks with the Silverlight tab highlighted:
If you use the CodeRush code templates heavily, and they specify the author of the source code, you may find the IDE | User Info options page interesting. On this page, you can specify your first, last and middle name, and then use them inside the text expansions, for example, to create a file header and specify its author.
DXCore string providers are functions that return strings, and can be used to provide calculated information (e.g., date/time stamps, user names, active file name, etc) inside text expansions or DXCore plug-ins.
