Properties
CanRead
Whether or not the property is readable, i.e. has a public getter.
Property Value
CanWrite
Whether or not the property is writable, i.e. has a public setter.
Property Value
IsAutoProperty
Whether or not the property is likely auto-implemented.
Property Value
Remarks
Auto-property detection is heuristic, relying on the method's IL instructions and the name of its backing field. This can often be interpreted as a signal that the property won't receive property-change notifications, since to do so (whether explicitly or via some weaver/source generator) requires an implementation that is different from the auto-generated getter and setter.
Caveats: This only works as a negative signal (a value of false does not prove that the property will receive notifications, even if the declaring type implements INotifyPropertyChanged), and is somewhat fuzzy even as a negative signal; it is theoretically possible for a source generator or IL weaver to leave behind all the markers of an auto property and still emit notifications, although no known libraries actually do so.
IsField
Whether or not the underlying member is a field, rather than a real property.
Property Value
Remarks
For binding convenience, fields and properties are both called "properties" for descriptors, as the external access pattern is the same; however, mutable fields can never reliably emit property-change notifications regardless of whether the declaring type implements INotifyPropertyChanged, so this is usually used to emit some warning.
ValueType
The property's value type.
