Ошибка сервера в приложении system web

I’m trying to publish an ASP.NET MVC 4 Internet Application. After it’s been published, I go ahead and click the link for my website and find this:

Server Error in ‘/’ Application.

Could not load file or assembly ‘System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ or one of its dependencies. The system cannot find the file specified.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Assembly Load Trace: The following information can be helpful to determine why the assembly ‘System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ could not be loaded.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].

Stack Trace:

What I’ve tried so far:

• Modify the registry, failed. Also, I am not sure about whether this would solve my issue.
• Set the ‘System.Web.Http.WebHost Copy Local’ Property to ‘true’. That didn’t solve the issue either.

Update: the version of the System.Web.Http.WebHost is 4.0.20710.0

I created an ASP.NET web application MVC Core 2.2 project. Then I ran it in IIS Express. But I received the following error:

HTTP Error 500.24 — Internal Server Error An ASP.NET setting has been
detected that does not apply in Integrated managed pipeline mode.

Most likely causes: system.web/identity@impersonate is set to true.

Things you can try: If the application supports it, disable client
impersonation. If you are certain that it is OK to ignore this error,
it can be disabled by setting
system.webServer/validation@validateIntegratedModeConfiguration to
false.

This is my lunchSetting.json code:
