Open XAML without design editor in Visual Studio

Just a quick post about Visual Studio setting that disables the design editor for XAML files. If you prefer to work only with source code without Designer, you can configure it in the Tools -> Options:

  • For Visual Studio 2013 enable the setting Always open documents in full XAML view in the Text Editor -> XAML -> Miscellaneous

  • For Visual Studio 2015 set the Default document view to Source View in the XAML Designer -> General

Compilation directives for controlling XAML content

In C# in order to control what code should be executed we can use compilation directives #if, #else, #elif and #endif. For instance, we can compile certain code only in Debug mode and exclude one in Release. #if directive can be used not only to test for symbols DEBUG and RELEASE. We are able to define any symbols. Let’s take a look how to do that and how to use newly defined symbol in the code. For example, we want to add some funny log messages when symbol FUN_MODE is defined.

  1. First, define a new compilation symbol for the whole project in the project’s properties:Compilation directive XAML 1 FUN_MODE
  2. Then we can check for defined symbol in the code:
    #if FUN_MODE
        logger.Debug("Yahoo! It looks like our app finally works!");
    #else
        logger.Debug("Application started.");
    #endif

Everything is quite simple. The question is how to achieve the same in XAML code.
