How do I re-open my UWP app?

Hello Developers!

I've created a sample project to test with UWP platform build.

I ran the .sln in Visual Studio 2017 and all is well: the application is automatically opened and running!

I close the application by mistake...and now I want to re-open it, I actually really want to take the whole build directory, copy paste it to a SurfacePro windows 10 tablet and side load the application to run on my tablet.

Questions:

1. How do I re-open the application on my standalone? (its obviously worked before and I don't want to re-build it each time I want to open it...)

2. How do I side-load it to the tablet (of course I saw this post and many others... but I can't seem to HAVE the .appx package on my machine)

3. Why this is a Unity3D question? Of course it is, if it weren't for Unity I would have not be here asking this today... Oh and it's time there's more answered questions on this topic...)

Be well and thanks!
