All I got now is to make t...

My understanding of the Command Pattern is that you simply have 1 virtual method 'execute()', and all dependencies that an implementation might have are put in the constructor or through setter injection in the implementation (like discussed here). However, in the WPF implementation of the pattern, I noticed they are passing a generic a...

While defining style in resource dictionary you can use either x:Name="xyz" and x:Type="xyz". and can reference this style in XAML like {StaticResource xyz}. Most examples use 'x:Key', and the difference between 'name' and 'key' is that using 'x:name' lets you use this style definition code-behind? FIXES: The question is to...
