Niner since 2012
@Aleksander Moriarty: As far as I know, things like that can only be done with a Windows 8 app. I suggest you head down to https://msdn.microsoft.com/en-us/library/windows/apps/hh986964.aspx and go down the line of tutorials. For that, Notepad won't be useful enough. Windows 8 and Visual Studio 2012 is required. Visual Studio can be downloaded at https://www.microsoft.com/visualstudio/eng/downloads.
As usual, nice vid! But I'm stuck at the part where we get the "onclick" segment to work correctly. Because after I typed "substitute()" in the double quotes and refresh, nothing happens! A little help?
Can't find anything that has to do with NuGet Package Manager when right-clicking ".NET for Windows Store apps".
