私のテクニカルサポートの経歴により、この投稿にあまりにも多くの情報を入れてしまい、誰もそれを読むことに興味がなくなった可能性がありますが、私見では、情報が多いほど良いです。

アセンブリのバインドとリダイレクトについて、私が見逃している非常に基本的で基本的なものがあります。古いバージョンのアセンブリに対してコンパイルされたアプリケーションを最新バージョンにリダイレクトするポリシーDLLを作成しようとしています。私がすることは何もうまくいかないようです。以下に、実行する手順の概要を示します。Visual Studioを使用していませんが、.NETFrameworkとWindowsSDKに含まれているコマンドラインツールのみを使用しています。ステップ11で、アセンブリのv1.0.0バージョンに対してコンパイルされたアプリケーションを実行すると、アプリケーションがGACに登録されているv2.0.0アセンブリにリダイレクトされない理由を誰かに教えてもらえますか？

私が行ったことを実行するとき、コマンドを実行したディレクトリに注意する必要があります。

私が読むことになっているTFMを指摘するほど親切にしていただければ、RTFMの回答に満足しています。

よろしくお願いします、Reg

ステップ1：キーペアを作成して、アセンブリに厳密な名前を付けます。

初日からの私の全体的な問題は、周りに二重引用符がないことでした：

文化=中立

.configファイルを次のように変更します

culture = "neutral"

そして、すべてが魅力のように機能しました。構成ファイルのXMLの解析エラーを示すアセンブリバインディングデバッグアウトログログのエラーは便利であり、2日節約できた可能性があります。しかたがない。

この質問はもっと短いかもしれないと思います。

厳密に名前が付けられたアセンブリに対してコンパイルする場合は、アセンブリの正確なバージョンをGACに登録する必要があります。V1.0.0.0アセンブリに対してコンパイルされたアプリでは、アセンブリV1.0.0.0を登録/インストールする必要があります。V2.0.0.0アセンブリに対してコンパイルされたアプリでは、V2.0.0.0を登録/インストールする必要があります。両方のアプリを実行する場合は、両方のバージョンをインストールして登録する必要があります。私が知る限り、例外や、厳密に名前が付けられたアセンブリによる置換はありません。

これの要点は、あるバージョン用に記述されたコードは、アセンブリバージョンが将来のある時点で更新された場合（つまり、dll hell）、壊れることを恐れずに実行し続けることができるということです-古いバージョンの開発者が新しいバージョンに対して実行するようにベースアプリケーションを更新するまでのアセンブリ。

アセンブリのリダイレクトについて：
