Remove unnecessary ToString() calls.
Add ?? to simplify conditional initialization
Use TryGetValue and out variable initialization to simplify Quantity

Use Value<T> generic method instead of dynamic types.
There is a lot of overhead for dynamic and it seems overkill here.

Use the pattern matching is expression.
Refactor the LINQ queries to enumerate the collection (and create an
enumerator)
only once. The previous code had 3 enumerations.

the only asynchronous statement is the final statement of the method,
and
the task from the underlying method can be returned.

Use expression bodied members where applicable.
Remove the 'async' modifier and 'await' statements from methods where
the only asynchronous statement is the final statement of the method,
and

Use expression bodied members where applicable.
Remove the 'async' modifier and 'await' statements from methods where

ViewModels/Annotations/CardExpiration:
Use the out variable initializer to simplify the validation of the
card expiration date.

Use property initializer syntax instead of constructor body

Use expression bodied property to return the calculated 'Disabled'
property
