Syntax

<legacyCorruptedStateExceptionsPolicy enabled="true|false"/>

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description
`enabled`	Required attribute. Specifies that the application will catch corrupting state exception failures such as access violations.

enabled Attribute

Value	Description
`false`	The application will not catch corrupting state exception failures such as access violations. This is the default.
`true`	The application will catch corrupting state exception failures such as access violations.

Child Elements

None.

Parent Elements

Element	Description
`configuration`	The root element in every configuration file used by the common language runtime and .NET Framework applications.
`runtime`	Contains information about assembly binding and garbage collection.

Remarks

In the .NET Framework version 3.5 and earlier, the common language runtime allowed managed code to catch exceptions that were raised by corrupted process states. An access violation is an example of this type of exception.

Starting with the .NET Framework 4, managed code no longer catches these types of exceptions in catch blocks. However, you can override this change and maintain the handling of corrupted state exceptions in two ways:

Set the <legacyCorruptedStateExceptionsPolicy> element's enabled attribute to true. This configuration setting is applied processwide and affects all methods.

-or-

Apply the System.Runtime.ExceptionServices.HandleProcessCorruptedStateExceptionsAttribute attribute to the method that contains the exceptions catch block.

This configuration element is available only in the .NET Framework 4 and later.

Example

The following example shows how to specify that the application should revert to the behavior before the .NET Framework 4, and catch all corrupting state exception failures.

XML

<configuration>  
   <runtime>  
      <legacyCorruptedStateExceptionsPolicy enabled="true" />  
   </runtime>  
</configuration>
