 ## Suppress a warning
 
-Violations to this rule cannot be suppressed inline.
+Because this rule is reported at the compilation level and not in a *.cs* or *.vb* source file, you can't suppress violations to this rule inline or via an `.editorconfig` file.
 
-To disable the rule for a file, folder, or project, set its severity to `none` in the [configuration file](../../../fundamentals/code-analysis/configuration-files.md).
+To disable the rule for a project, add `<NoWarn>$(NoWarn);MSTEST0001</NoWarn>` to the project file or `Directory.Build.props` file.
+
+To control the severity of this rule, you can do it only via a `.globalconfig` file. For more information, see [Configuration files](../../../fundamentals/code-analysis/configuration-files.md#global-analyzerconfig).
