SYSLIB0046: ControlledExecution.Run should not be used

  • Article

The ControlledExecution.Run(Action, CancellationToken) method might corrupt the process and should not be used in production code. This method runs code that can be aborted asynchronously. While this method is new for .NET 7, it's also marked as obsolete to discourage you from using it. For more information, see Proposal for non-cooperative abortion of code execution.

Suppress a warning

If you must use the obsolete APIs, you can suppress the warning in code or in your project file.

To suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the warning.

// Disable the warning.
#pragma warning disable SYSLIB0046

// Code that uses obsolete API.
// ...

// Re-enable the warning.
#pragma warning restore SYSLIB0046

To suppress all the SYSLIB0046 warnings in your project, add a <NoWarn> property to your project file.

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
   ...
   <NoWarn>$(NoWarn);SYSLIB0046</NoWarn>
  </PropertyGroup>
</Project>

For more information, see Suppress warnings.
