Windows PC上のASP.NET Coreのみでファイルまたはアセンブリ「Microsoft.AspNetCore.Connections.Abstractions」をロードできませんでした

このASP.NET Core 2.1プロジェクトは、Mac OSで正常に動作します。ただし、Windows PCから実行すると、この例外がスローされます。同じバージョンの.NET Core SDKを使用して、2台のWindowsマシンからこれを実行しようとしました。

.NET Core SDK 2.1.302を再インストールし、2.1.401にアップグレードしようとしました。ヘルプを感謝します。

この問題は、.NET Core 2.1.xの既知の問題で、.NET Core 2.1.5で修正された以降です。 https://github.com/dotnet/core-setup/issues/4512 を参照してください。

.NET Core SDKの更新後に「System.IO.FileLoadException」が原因でエラーが発生する場合は、おそらく https://github.com/dotnet/core-setup/issues/4376 。

最善の解決策は、.NET Core 2.1.5以降にアップグレードすることです。

アップグレードできない場合、別の回避策は、プロジェクトを

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.3" />

https://github.com/dotnet/core-setup/issues/4376 で説明されているように、この問題の原因は、共有フレームワークから意図せずにアップグレードしていることです。例えば：

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.0" />
<PackageReference Include="Microsoft.AspNetCore.SignalR" Version="1.0.1" />

Microsoft.AspNetCore.All 2.1.0はMicrosoft.AspNetCore.SignalR1.0.0に依存していますが、プロジェクトはMicrosoft.AspNetCore.SignalR1.0.1にアップグレードされています。 dotnet publishを実行すると、Microsoft.AspNetCore.SignalR 1.0.1およびget️が発行フォルダー内の推移的な依存関係になります。これは公開トリミング落とし穴です https://natemcmaster.com/blog/2018/08/29/netcore-primitives-2/ 。

これは次の結果になります

+=================+===============================+================================+============================+
| AspNetCore.All  |  M.A.Connections.Abstractions |  M.A.Connections.Abstractions  |  Which M.A.C.Abstractions  |
|                 |  (in shared framework)        | (in publish dir)               |  should load               |
+=================+===============================+================================+============================+
| 2.1.0           |  2.1.0                        |  2.1.1                         |  publish dir               |
+-----------------+-------------------------------+--------------------------------+----------------------------+
| 2.1.3           |  2.1.3                        |  2.1.1                         |  shared framework*         |
+-----------------+-------------------------------+--------------------------------+----------------------------+

*これはバグであり、 https://github.com/dotnet/core-setup/issues/4512 は将来の2.1.xアップデートで修正を取得することを追跡します。

Microsoft.AspNetCore.Allがない場合は、Microsoft.AspNetCore.Appを使用してバージョンを2.1.3に設定できます。それらはまったく同じです。

<PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.3"/>

Web API CoreプロジェクトファイルにMicrosoft.AspNetCore.Allが含まれていませんでした。アイテムグループに手動で追加し、修正しました。

Microsoft.AspNetCore.Allを2.1.0からアップグレードして問題を解決しました-> 2.1.3（SDKを2.1.401にアップグレード）

それでも、これがMacでは動作するがWindowsでは動作しない理由がわからない。

Connection.Abstractions dllを手動で追加できます
