 Once a particular non-ref-valued property or non-ref-valued indexer has been selected, the accessibility domains of the specific accessors involved are used to determine if that usage is valid:
 
 - If the usage is as a value ([§12.2.2](expressions.md#1222-values-of-expressions)), the get accessor shall exist and be accessible.
-- If the usage is as the target of a simple assignment ([§12.23.2](expressions.md#12232-simple-assignment)), the set accessor shall exist and be accessible.
-- If the usage is as the target of compound assignment ([§12.23.5](expressions.md#12235-compound-assignment)), or as the target of the `++` or `--` operators ([§12.8.16](expressions.md#12816-postfix-increment-and-decrement-operators), [§12.9.7](expressions.md#1297-prefix-increment-and-decrement-operators)), both the get accessors and the set accessor shall exist and be accessible.

 > *Example*: In the following example, the property `A.Text` is hidden by the property `B.Text`, even in contexts where only the set accessor is called. In contrast, the property `B.Count` is not accessible to class `M`, so the accessible property `A.Count` is used instead.
