WmiConfigurationAttribute Class
 

The WmiConfiguration attribute indicates that an assembly contains code that implements a WMI provider by using the WMI.NET Provider Extensions model. The attribute accepts parameters that establish the high-level configuration of the implemented WMI provider.

Note: the WMI .NET libraries are now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.

NameDescription
System_CAPS_pubmethod WmiConfigurationAttribute

Initializes a new instance of the T:System.Management.WmiConfigurationAttribute class that specifies the WMI namespace in which the WMI provider will expose classes.

NameDescription
System_CAPS_pubproperty

Gets or sets the hosting group for the WMI provider.

System_CAPS_pubproperty

Gets or sets the hosting model for the WMI provider.

System_CAPS_pubproperty

Gets or sets a value that specifies whether the WMI provider can impersonate its callers. If the value is false, the provider cannot impersonate, and if the value is true, the provider can impersonate.

System_CAPS_pubproperty

Gets or sets a Security Descriptor Definition Language (SDDL) string that specifies the security descriptor on the namespace in which the provider exposes management objects.

System_CAPS_pubproperty

Gets or sets the WMI namespace in which the WMI provider exposes classes.

System_CAPS_pubproperty

Gets or sets a security descriptor for the WMI provider. For more information, see the SecurityDescriptor property information in the "__Win32Provider" topic in the MSDN online library at http://www.msdn.com.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsDefaultAttribute

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The following table lists the parameters accepted by this attribute along with what aspect of the provider configuration it enables you to control.

Parameter

Configures

Scope

The namespace in which your provider exposes classes.

NamespaceSecurity

  • The security (DACL) on the namespace used.

HostingModel

  • The hosting model that will be used by the provider.

IdentifyLevel

  • The impersonation mode of the provider.

HostingGroup

The hosting group that the provider belongs to. This parameter only applies to in-process providers.

SecurityRestriction

The security (DACL) on the WMI provider.

// Specify that this assembly contains code that implements a WMI
// Provider. Use the assembly:WmiConfiguration attribute to define
// the WMI namespace, the hosting model, and the impersonation mode
// of the WMI provider.
// The attribute below specifies that the class this provider
// exposes to WMI will be in the root/MortgageCalc namespace, will
// use the decoupled hosting model and will not allow the provider
// to impersonate its callers.
