System.Web.WebPages.Html.HtmlHelperに定義が含まれていません

私はこの同じ質問に多くの質問をしていますが、私はそれらのほとんどを試してみました。私はそれに複数のプロジェクトを持つソリューションを持っています。彼らは異なった.netバージョン上にあったので、.Net 4.5に、MVC 4からMVC 5にアップグレードしました。私の現在の問題は、ビューファイルでは、それは剃刀の構文を認識しません。 @model、ViewBag、ActionLink、DisplayNameForなどの間違った用語）System.Web.WebPages.Html.HtmlHelperに定義が含まれていません

私のパッケージが最新であり、webconfigファイルが正しく指していることを確認しました。最後の小数点または最上位の小数点を指す必要がありますか？たとえば、両方とも試しても、 <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" /または<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />です。

私もbin、objを削除して、一時的なものを消去し、清掃し、再構築しました。私が逃しているものが見えますか？

コンパイル時にどうなりますか？どのようなエラーが出ますか？ – CodingYoshi

@ CodeYoshiこれはコンパイル時に発生するエラーです。ファイルまたはアセンブリ 'System.Web.Helpers'またはその依存関係の1つを読み込めませんでした。見つかったアセンブリのマニフェスト定義がアセンブリ参照と一致しません。（例外HRESULTから：0x80131040）私は質問に完全なエラーを追加しました。 –

あなたのエラーは問題が何であるかがわかります。あなたの参照にSystem.Web.Helpersのために持っているどんなDLLバージョンでも、どこかにプロジェクトファイルが一致していません。各プロジェクトを右クリックして[プロジェクトをアンロード]をクリックし、使用できないプロジェクトを右クリックして[プロジェクトの編集]を選択します。 System.Web.Helpersを探し、各プロジェクトでバージョン番号が一貫していることを確認してください。

ありがとうございました。 web.helpersを含む2つのプロジェクトを見ると、それらは同じであるように見えます。 .. \ .. \ packages \ Microsoft.AspNet.WebPages.3.2.3 \ lib \ net45 \ System.Web.Helpers.dll True '他にも何かがありますか？ –

私はそれを理解したと思う。 'Version = 3.0.0.0'を' 3.2.3.0'に変更した場合、System.Web.WebPagesの新しいエラーが発生します。同様のエラーごとに同じことをすれば、少なくともこのエラーを解決できるはずです。正しい？ –

だから私はこの変更を始めましたが、これで固まってしまった 'System.Web.WebPages.Razor、Version = 3.0.0.0'をファイルまたはアセンブリをロードできませんでした。これをバージョン3.2.3.0に変更するのか、そのままにしますat 3.0.0.0 –

System.Web.WebPages.Html.HtmlHelperに定義が含まれていません

答えて
