RequiredRuntimeAttribute Class
Defines the metadata attribute that task authors use to identify whether the task requires a specific version of the CLR runtime.
MSBuild is now included in Visual Studio instead of the .NET Framework. You can use MSBuild 12.0 side-by-side with versions previously deployed with the .NET Framework.For more information, see What's New in MSBuild 12.0.
Assembly: Microsoft.Build.Framework (in Microsoft.Build.Framework.dll)

![]() | RequiredRuntimeAttribute(String^) | Initializes a new instance of the RequiredRuntimeAttribute class. MSBuild is now included in Visual Studio instead of the .NET Framework.

![]() | RuntimeVersion | Gets the CLR runtime version the attribute was constructed with, such as "v2.0." MSBuild is now included in Visual Studio instead of the .NET Framework. You can use MSBuild 12.0 side-by-side with versions previously deployed with the .NET Framework.For more information, see What's New in MSBuild 12.0. |

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.
Note |
|---|
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. |
