CreateDialog, CreateWindow or any other window\dialog creation function fails and GetLastError is 0

As an app developer, it's impossible not to have the task to display an icon in the app. One of the common ways to display icons , instead of using images or SVGs , is by using font files (.ttf, .otf or .woff). Although font files are usually used to display text with a specific font, but they can also be used to display icons . Instead of containing glyphs with letters , they contain glyphs with icons : There are different types of font technologies but the most common ones today are the TrueType (.ttf), OpenType (.otf) or the WOFF (.woff) font files.

The  device independence is a key aspect given the myriad of display sizes and technologies which exist today. Referring to an icon inside of a icon font file  works by knowing the hexadecimal val...

The issue is not just about declaration of prefixes. Having separate prefixes bloats the XAML a lot because you have to use a separate prefix for every object you reference from the corresponding namespace. In my example there are 4 prefixes to deal with! As a solution to get rid of all the namespaces, a dark thought might have crossed your mind: remove all the CLR namespaces in the library’s code and just have one namespace! But you love your C# namespaces, they give class scope and separation, it’s...
