Remarks
Razor Pages uses the current request's HTTP method to select a handler method. When no handler is available or selected, the page is immediately executed. This may cause runtime errors if the page relies on the handler method to execute and initialize some state. This setting attempts to avoid this class of error for HTTP OPTIONS requests by returning a 200 OK response.
This property is associated with a compatibility switch and can provide a different behavior depending on the configured compatibility version for the application. See CompatibilityVersion for guidance and examples of setting the application's compatibility version.
Configuring the desired of the value compatibility switch by calling this property's setter will take precedence over the value implied by the application's CompatibilityVersion.
If the application's compatibility version is set to Version_2_2 then this setting will have value true unless explicitly configured.
If the application's compatibility version is set to Version_2_1 or lower then this setting will have value true unless explicitly configured.
