RequiredRuntimeAttribute Class


When marked with the RequiredRuntimeAttribute, a task indicates that it has stricter runtime requirements than a regular task - this tells MSBuild that it will need to potentially launch a separate process for that task if the current runtime does not match the version requirement. This attribute is currently non-functional since there is only one version of the CLR that is capable of running MSBuild v2.0 or v3.5 - the runtime v2.0

A task marked with the RequiredRuntimeAttribute indicates that it has a stricter runtime requirement than a regular task. It alerts MSBuild that it may need to start a separate process for the task if the current CLR runtime version does not match the required version.


This attribute is currently non-functional because only one version of the CLR (2.0) is capable of running either MSBuild version 2.0 or 3.5.

Constructor taking a version, such as "v2.0".



Returns the runtime version the attribute was constructed with, e.g., "v2.0"


When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)



Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)

Returns the hash code for this instance.

(Inherited from Attribute)

Gets the Type of the current instance.

(Inherited from Object)

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.
