.NET Framework 2.0

Namespace: System.Security
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public ref class HostSecurityManager

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public class HostSecurityManager

JScript

SerializableAttribute 
ComVisibleAttribute(true) 
public class HostSecurityManager

Remarks

When you create a new AppDomain, the common language runtime queries the AppDomainManager for the presence of a HostSecurityManager, which participates in making security decisions for the AppDomain. Host providers should implement a host security manager that inherits from the HostSecurityManager class.

Notes to Inheritors Some members of a HostSecurityManager are called whenever an assembly is loaded, either implicitly or explicitly. The get accessor for the DomainPolicy property and the ProvideAssemblyEvidence and ProvideAppDomainEvidence methods must not load any assemblies, because doing so will result in the members of the HostSecurityManager being recursively called. To avoid circular references, you should create new instances of classes that can cause assemblies to be loaded, either implicitly or explicitly, in the constructor of a class that derives from HostSecurityManager.

Example

The following code example shows a very simple implementation of a HostSecurityManager.
