It supports all WPF functionality including data binding and automatic layout management. It is used to author user interfaces targeting Windows Presentation Foundation. Like the Windows Forms designer it supports the drag and drop metaphor. The WPF designer, codenamed Cider, was introduced with Visual Studio 2008. The designer generates either C# or VB.NET code for the application. The UI is linked with code using an event-driven programming model. Data-bound controls can be created by dragging items from the Data Sources window onto a design surface. Controls that display data (like textbox, list box, grid view, etc.) can be bound to data sources like databases or queries. Layout can be controlled by housing the controls inside other containers or locking them to the side of the form. The Windows Forms designer is used to build GUI applications using Windows Forms. The debugger can be configured to be launched when an application running outside the Visual Studio environment crashes. Multi-threaded programs are also supported. The Visual Studio debugger can also create memory dumps as well as load them later for debugging. If source code is not available, it can show the disassembly. If source code for the running process is available, it displays the code as it is being run. In addition, it can also attach to running processes and monitor and debug those processes. It works with both managed code as well as native code and can be used for debugging applications written in any language supported by Visual Studio. Visual Studio includes a debugger that works both as a source-level debugger and as a machine-level debugger. The code editor is used for all supported languages. In Visual Studio 2008 onwards, it can be made temporarily semi-transparent to see the code obstructed by it. Autocomplete suggestions appear in a modeless list box over the code editor window, in proximity of the editing cursor. IntelliSense is supported for the included languages, as well as for XML and for Cascading Style Sheets and JavaScript when developing web sites and web applications. Like any other IDE, it includes a code editor that supports syntax highlighting and code completion using IntelliSense for variables, functions, methods, loops and LINQ queries. Variables are initially presented according to simplified model (name → value) but you can switch to more realistic model (name → address/id → value). Good understanding of how function calls work is especially important for understanding recursion. Stepping into a function call opens a new window with separate local variables table and code pointer. * Faithful representation of function calls. You can think of this light-blue box as a piece of paper where Python replaces subexpressions with their values, piece-by-piece. If you use small steps, then you can even see how Python evaluates your expressions. Steps follow program structure, not just code lines. Press F6 for a big step and F7 for a small step. Just press Ctrl+F5 instead of F5 and you can run your programs step-by-step, no breakpoints needed. Once you're done with hello-worlds, select View → Variables and you see how your programs and shell commands affect Python variables.
