- StaticResource and Dynamic Resource- StaticResource and CompileResource- WPF does not support Logical Resources- None of the above
Logical resources are of two types :
1) StaticResources
* StaticResource is applied only once (first time when it is used).
* StaticResource has lesser overhead as it is applied only once during the runtime of the application.
* StaticResources always get loaded the first time window/page is loaded irrespective of its use during start up.
* StaticResources can be used for DependencyProperty as well as normal .net property.
* StaticResources has to be defined before it is used. Hence, StaticResources can not be forward referenced.
2) DynamicResources
* DynamicResource is applied every time when resource changes e.g. system colors can be changed using control panel. So if system colors has been used as resource, than update is required. DynamicResource will take care of such change in resource.* DynamicResource has more overhead as it is applied whenever the resource value changes. In order to do this, DynamicResource has to keep tracking about the changes in the resource during runtime also.
* DynamicResources are not loaded until it is actually used. So this results in better load time.
* DynamicResource can only be used for DependencyProperty.
* DynamicResources can use the forward references.
