and click Use Company Credentials, then click Log
In and sign into LUC Box; once you’re signed-in, click
Start Syncing to create a synchronized Box Sync
folder on your PC’s hard drive linked to the cloud

directory, and it’s pinned in Explorer/Finder; on
Windows a link to it is also on your PC Desktop

Creating a Sharable Box
Xamarin Solution – 2
• The window that opens shows your new Solution
on the left in the Xamarin Studio “Solution Pad”
with one Project, the hello Project you just created
• The window in the middle, the Editing Pad, shows
the source for the Program.cs program you've
created in Xamarin Studio – you can edit it there
• If you go back to the Welcome Page (in the View
menu), or if you close and reopen Xamarin
Studio, your new shareable Solution on Box will
appear there from now on – just click it to open it

Using your Xamarin
Solution for the Class
• You will create answers for (almost) all class
exercises and assignments in your userid170
Xamarin Box Solution, not by Submitting on Sakai
– The hello Project you created in your Solution is the
first of many Projects that you will create for the class
• For most Lab exercises/homework assignments
you will create separate Xamarin Projects in that
Solution, one per exercise/assignment
– Right-click your userid170 Solution name, select Add
 Add New Project, and fill in Project information like
you did for hello, but with an assignment-related name
