        <summary>
          <para>Specifies the method can be executed by only one thread at a time.</para>
          <para>This option specifies that before a thread can execute the target method, the
      thread is required to acquire a lock on either the current
      instance or the <see cref="T:System.Type" />
      object for the method's class. If the target method is an instance method, the
      lock is on the current instance. If the target is a static method, the lock is
      on the <see cref="T:System.Type" /> object. Specifying this option causes the target method to behave as though its
      statements are enclosed by <see cref="M:System.Threading.Monitor.Enter(System.Object)" /> and <see cref="M:System.Threading.Monitor.Exit(System.Object)" />
      statements locking the previous described object. This option and the <see cref="T:System.Threading.Monitor" /> methods are functionally equivalent, and both
      are functionally equivalent to enclosing the target method's code in a C# lock
      (this)
      statement. </para>
          <block subset="none" type="note">
            <para>Because this option holds the lock for
         the duration of the target method, it should be used only when the entire method
         must be single threaded. Use the <see cref="T:System.Threading.Monitor" /> methods (or the C#
         lock statement) if the object lock can be taken after the method begins, or
         released before the method ends. Any mechanism that uses locks can cause an
         application to experience deadlocks and performance degradation; for these
         reasons, use this option with care.</para>
            <para> For most languages, it is recommended that the notion of
         "synchronized" be attached to methods using language syntax instead of custom
         attributes.</para>
