As a design‑time dynamic property can be used wherever a static property can be used, there are a number of factors in deciding the type of property to use.
If there are instances of the class containing the property and you want to avoid a reorganization, use a design‑time dynamic property because:
A database reorganization is not required when a design‑time dynamic property is added, changed, or deleted. However, a database reorganization would be required for a static property.
If there are no instances of the class containing the property, use a static property because:
Accessing a static property in an application is faster than accessing a design‑time dynamic property.
A database reorganization is not required when a static property is added, changed, or deleted. There is no advantage in using a design‑time property.
