| HelpLink | Gets or sets a link to the help file associated with this exception. (Inherited from Exception.) |
| HResult | Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.) |
| InnerException | Gets the Exception instance that caused the current exception. (Inherited from Exception.) |
| Message | Gets a message that describes the current exception. (Inherited from Exception.) |
| Source | Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.) |
| StackTrace | Gets a string representation of the frames on the call stack at the time the current exception was thrown. (Inherited from Exception.) |
| Name | Description | |

| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetBaseException | When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the runtime type of the current instance. (Inherited from Exception.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |

In XAML, this exception is thrown when the just-in-time (JIT) compiler detects a call to a member that has the SecurityCriticalAttribute attribute. Such members cannot be used in Windows Phone apps. |
MemberAccessException is the base class for FieldAccessException, MethodAccessException, MissingMemberException, MissingMethodException, and MissingFieldException. These exceptions are thrown when a class member is not found or access to the member is not permitted.
MemberAccessException can be thrown when reflection is used for late-bound access to members. For example, it can be thrown by the following methods: Type::InvokeMember, MethodBase::Invoke, FieldInfo::GetValue, and Delegate::DynamicInvoke.
MemberAccessException uses the HRESULT COR_E_MEMBERACCESS, which has the value 0x8013151A.
