asp.net mvc : System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a 의 에러 (error) 방안

개발하는 제 pc 환경에서는 이슈가 없었지만, 실서버의 환경에서 배포 후 오류 발생되어 화면이 뜨지 않아 곤란한 상황이 발생되었습니다.

 

 

문제 발생 

 

error CS0012: 'System.Object' 형식이 참조되지 않은 어셈블리에 정의되었습니다. 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' 어셈블리에 참조를 추가해야 합니다.

해결방안

 

아래와 같이 System.Runtime 의 버전을 오류 발생한 로그에 맞게 값을 지정해 주어야 오류 없이 사용이 가능합니다.

<compilation debug="true" defaultLanguage="c#" targetFramework="4.5.2">
    <assemblies>
        <add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </assemblies>
</compilation>
