웹 사이트를 처음 시작할 때이 오류가 발생합니다

Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

.NET 4를 사용하고 있으며 Visual Studio에서 사이트를 시작하고 있습니다.

내가 최근에 변경 한 유일한 것은 내 프로젝트에 Simple Injector (Nuget을 통해)를 추가하는 것입니다.

스택 추적은 다음과 같습니다
