Remarks

This attribute affects only unmanaged applications that host the common language runtime and implement host protection, such as SQL Server. If the code is run in a client application or on a server that is not host-protected, the attribute "evaporates"; it is not detected and therefore not applied. When applied, the security action results in the creation of a link demand based on the host resources the class or method exposes.

If the host does not have programming model requirements, the link demands do not occur.

This attribute identifies the following:

• Methods or classes that do not fit the host programming model, but are otherwise benign.
• Methods or classes that do not fit the host programming model and could lead to destabilizing server-managed user code.
• Methods or classes that do not fit the host programming model and could lead to a destabilization of the server process itself.
