Attributes and Elements

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

Attributes

None.

Child Elements

Element	Description
<requiredRuntime>	Specifies that the application supports only version 1.0 of the common language runtime. Applications built with runtime version 1.1 should use the <supportedRuntime> element.
<supportedRuntime>	Specifies which versions of the common language runtime the application supports.

Parent Elements

Element	Description
configuration	The root element in every configuration file used by the common language runtime and .NET Framework applications.

Remarks

The <supportedRuntime> element should be used by all applications built using version 1.1 or later of the runtime. Applications built to support only version 1.0 of the runtime must use the <requiredRuntime> element.

The startup code for an application hosted in Microsoft Internet Explorer ignores the <startup> element and its child elements.

Example

The following example shows how to specify the runtime version in a configuration file.

<!-- When used with version 1.0 of the .Net runtime -->
<configuration>
   <startup>
      <requiredRuntime version="v1.0.3705" safemode="true"/>
   </startup>
</configuration>
<!-- When used with version 1.1 (or later) of the .Net runtime -->
<configuration>
   <startup>
      <supportedRuntime version="v1.1.4322"/>
      <supportedRuntime version="v1.0.3705"/>
   </startup>
</configuration>
