Angular - How to fix 'property does not exist on type' error?
In my situation I had my property auto initialize a command in a ViewModel for a View. I changed the property to use expression bodied initializer and the command CanExecute stopped working.
A property can have a 'get' accessor only, which is done in order to make that property read-only When implementing a get/set pattern, an intermediate variable is used as a container into which a value can be placed and a value extracted.
Descriptors like property need to be in the type's dictionary to work their magic. So those in a class definition primarily affect the behaviour of instances of the class, with minimal effect on the behaviour of the class itself (since the class is the type of the instances).
