Read Only Property Assignment

Identifies Property assigment references where Set or Let Property Members do not exist.

NEW! This inspection is only available in pre-release builds.

Reasoning

In general, the VBE editor catches this type of error and will not compile. However, there are a few scenarios where the error is overlooked by the compiler and an error is generated at runtime. To avoid the runtime error scenarios, the inspection flags all assignment references of a read-only property.
