Custom attribute that, when applied on a property of type ICommand named say Foo, automatically create a
new command class based on a method named ExecuteFoo and an optional property or method named CanExecuteFoo.

public class CommandAttribute : LocationLevelAspect, IAspectProvider, IAspect, IService
The CommandAttribute type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | CommandAttribute |
Initializes a new instance of the CommandAttribute class.
|
Properties| Name | Description | |
|---|---|---|
 | AspectPriority |
Gets or sets the weaving priority of the aspect.
(Inherited from Aspect.) |
| AttributeExclude |
If true, indicates that this attribute removes all other instances of the
same attribute type from the set of elements defined by the current instance.
(Inherited from MulticastAttribute.) |
| AttributeInheritance |
Determines whether this attribute is inherited
(Inherited from MulticastAttribute.) |
| AttributePriority |
Gets or sets the priority of the current attribute in case that multiple
instances are defined on the same element (lower values are processed before).
(Inherited from MulticastAttribute.) |
| AttributeReplace |
Determines whether this attribute replaces other attributes found on the
target declarations.
(Inherited from MulticastAttribute.) |
| AttributeTargetAssemblies |
Gets or sets the assemblies to which the current attribute apply.
(Inherited from MulticastAttribute.) |
| AttributeTargetElements |
Gets or sets the kind of elements to which this custom attributes applies.
(Inherited from MulticastAttribute.) |
| AttributeTargetExternalMemberAttributes |
Gets or sets the visibilities, scopes, virtualities, and implementation
of members to which this attribute applies, when the member is external to the current module.
(Inherited from MulticastAttribute.) |
| AttributeTargetExternalTypeAttributes |
Gets or sets the visibilities of types to which this attribute applies,
when this type is external to the current module.
(Inherited from MulticastAttribute.) |
| AttributeTargetMemberAttributes |
Gets or sets the visibilities, scopes, virtualities, and other characteristics
of members to which this attribute applies.
(Inherited from MulticastAttribute.) |
| AttributeTargetMembers |
Gets or sets the expression specifying to which members
this instance applies.
(Inherited from MulticastAttribute.) |
| AttributeTargetParameterAttributes |
Gets or sets the passing style (by value, out or ref)
of parameters to which this attribute applies.
(Inherited from MulticastAttribute.) |
| AttributeTargetParameters |
Gets or sets the expression specifying to which parameters
this instance applies.
(Inherited from MulticastAttribute.) |
| AttributeTargetTypeAttributes |
Gets or sets the attributes of types to which this attribute applies. Visibility, scope (Instance or Static)
and generation are the only categories that are taken into account; attributes of other categories are ignored.
(Inherited from MulticastAttribute.) |
| AttributeTargetTypes |
Gets or sets the expression specifying to which types
this instance applies.
(Inherited from MulticastAttribute.) |
| CanExecuteMethod |
Gets or sets the name of the method that is called to determine whether the command can be executed.
This method corresponds to the CanExecute(Object) method.
|
| CanExecuteProperty |
Gets or sets the name of the property that is evaluated to determine whether the command can be executed.
This property corresponds to the CanExecute(Object) method.
|
| ExecuteMethod |
Gets or sets the name of the method that implements the command logic. This method corresponds to the
to the Execute(Object) method. It is called every time the command is invoked.
|
 | SerializerType |
Gets or sets the Type of the serializer (a type derived
from AspectSerializer) used to serialize the aspect instance
at build time and deserialize it at runtime.
(Inherited from Aspect.) |
| UnsupportedTargetAction |
Specifies the action to take when the aspect is applied to an unsupported target element. This property affects only simple aspects, not composite aspects.
(Inherited from Aspect.) |
Methods| Name | Description | |
|---|---|---|
| CompileTimeInitialize |
Method invoked at build time to initialize the instance fields of the current aspect. This method is invoked
before any other build-time method.
(Overrides LocationLevelAspect.CompileTimeInitialize(LocationInfo, AspectInfo).) |
| CompileTimeValidate(Object) |
Method invoked at build time to ensure that the aspect has been applied to the right target.
(Inherited from LocationLevelAspect.) |
| CompileTimeValidate(LocationInfo) |
Method invoked at build time to ensure that the aspect has been applied to the right target.
(Inherited from LocationLevelAspect.) |
 | CreateAspectConfiguration |
Method invoked at build time to create a concrete AspectConfiguration instance specifically
for the current Aspect type.
(Inherited from Aspect.) |
| GetAspectConfiguration |
Method invoked at build tome to get the imperative configuration of the current Aspect.
(Inherited from Aspect.) |
| SetAspectConfiguration(AspectConfiguration, LocationInfo) |
Method invoked at build time to set up an AspectConfiguration object according to the current
Aspect instance and a specified target element of the current aspect.
(Inherited from LocationLevelAspect.) |
| SetAspectConfiguration(AspectConfiguration, Object) |
Method invoked at build time to set up an AspectConfiguration object according to the current
Aspect instance and a specified target element of the current aspect.
(Inherited from LocationLevelAspect.) |
RemarksDefault naming conventions can be overridden by setting the ExecuteMethod, CanExecuteMethod or CanExecuteProperty aspect properties.
When used in a class that has NotifyPropertyChangedAttribute applied, the CanExecuteChanged event is fired whenever a change of the property specified by CanExecuteProperty is detected. The SynchronizationContext of the thread on which the instance of the target class was created is used to fire the event. For example, if the instance is created on a thread where Dispatcher is running, the event will be fired from this thread. If Current was null, the event is fired on the thread on which the notification of property change was received.
