アンマネージ C++ コード (boost など) をラップするために、C++/CLI で DLL を作成しました。私がいる限り、これはかなりうまくいきます
- 依存するすべての DLL を 1 つのフォルダーに入れ、
%PATH%環境を介してそのフォルダーを IIS に伝達します (システムの再起動が必要です)。
binただし、Microsoft は、アプリケーション パスの下のディレクトリ内にすべての依存関係を配置するだけで十分であると述べています。これは、次のように言うことで終わります。

Microsoftなどからの提案を見て、それに応じて調整しましたweb.config。どちらも私にとってはうまくいきませんでした。
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="/bin;bin/modules;/modules;\modules;bin\modules" />
<dependentAssembly>
<assemblyIdentity name="boost_chrono-vc100-mt-gd-1_52" publicKeyToken="0" culture="neutral" />
<codeBase version="0.0.0.0" href="file:///C:/app/bin/modules/boost_chrono-vc100-mt-gd-1_52.dll" />
</dependentAssembly>
</assemblyBinding>
</runtime>
このアプリケーション専用の特定のパスを IIS に伝える可能性はありますかweb.config? 実稼働システムでは、これらすべてのライブラリをシステム全体で利用できるようにすることはあまり賢明ではないと思い%PATH%ます。少なくとも、どの DLL が見つからなかったのかは興味深いでしょう (依存関係ウォーカーについては知っていますが、すべての DLL が同じディレクトリにあるため、欠落しているファイルについて文句を言うことはありません)。
