Edited the title as this appears to be a typo in the SDK LicensingBackstageViewModel class.
I was handed a stub of a project from a third party. Basically, the start of a project with little functionality. One of the first things I noticed is that when run in Debug mode from VS2022, it pops up a little licensing checkbox on the Licensing settings page of ArcGIS Pro, as seen below:

Clicking the box under Enable does the obvious, allow the addin to be used. However, it wasn't saving that setting between session, so I started looking in error messages to see what I could find and came across this:
System.Windows.Data Error: 40 : BindingExpression path error: 'ShowWorkstatoin' property not found on 'object' ''LicensingBackstageViewModel' (HashCode=28807604)'. BindingExpression:Path=ShowWorkstatoin; DataItem='LicensingBackstageViewModel' (HashCode=28807604); target element is 'Grid' (Name=''); target property is 'Visibility' (type 'Visibility')
There's a typo in there: "ShowWorkstatoin". I've searched the project multiple times with VS's search feature. I've used Windows search to search within the content of items in the folder of the project to no avail. I even set it upon my entire C:\ drive searching for the typo and everything comes up empty. I even did the search for LicensingBackstageViewModel and come up empty.
Is there a better way to be searching for this? Am I missing a handy VS feature to find text in a project that the search on the Solution Explorer is missing?
