Impossible de charger le fichier ou l'assembly 'Microsoft.AspNetCore.Connections.Abstractions' sur ASP.NET Core uniquement sur un PC Windows

Ce projet ASP.NET Core 2.1 fonctionne correctement sous Mac OS. Cependant, il lève cette exception lorsque je l'exécute à partir d'un ordinateur Windows. J'ai essayé d'exécuter cette opération à partir de deux ordinateurs Windows utilisant la même version de .NET Core SDK.

J'ai essayé de réinstaller .NET Core SDK 2.1.302, j'ai également essayé de passer à 2.1.401. Appréciez toute aide.

L'erreur est

System.IO.FileLoadException: Could not load file or Assembly 'Microsoft.AspNetCore.Connections.Abstractions, Version=2.1.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The located Assembly's manifest definition does not match the Assembly reference. (Exception from HRESULT: 0x80131040)

Ce problème est un problème connu de .NET Core 2.1.x qui était corrigé dans .NET Core 2.1.5 et plus récent. Voir https://github.com/dotnet/core-setup/issues/4512 .

Si vous obtenez des échecs dus à "System.IO.FileLoadException" après la mise à jour du SDK .NET Core, vous êtes probablement confronté à https://github.com/dotnet/core-setup/issues/4376 . 

La meilleure solution consiste à effectuer une mise à niveau vers .NET Core 2.1.5 ou plus récent.

Si vous ne pouvez pas mettre à niveau, une autre solution consiste à mettre à jour le projet à

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

La cause de ce problème, comme décrit dans https://github.com/dotnet/core-setup/issues/4376 , est une mise à niveau involontaire hors du cadre partagé. Par exemple:

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

Microsoft.AspNetCore.All 2.1.0 dépend de Microsoft.AspNetCore.SignalR 1.0.0, mais votre projet a été mis à niveau vers Microsoft.AspNetCore.SignalR 1.0.1. Lorsque vous dotnet publish, vous obtenez Microsoft.AspNetCore.SignalR 1.0.1 ET ⚠️ ses dépendances transitives dans votre dossier de publication. Il s'agit du piège publier de rognage décrit dans https://natemcmaster.com/blog/2018/08/29/netcore-primitives-2/ .

Cela se traduit par ce qui suit

+=================+===============================+================================+============================+
| 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*         |
+-----------------+-------------------------------+--------------------------------+----------------------------+

* Ceci est un bogue et https://github.com/dotnet/core-setup/issues/4512 recherche un correctif dans une future mise à jour 2.1.x.

Si vous ne possédez pas Microsoft.AspNetCore.All, vous pouvez utiliser Microsoft.AspNetCore.App et définir sa version sur 2.1.3. Ils sont tout à fait les mêmes:

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

J'ai résolu le problème en mettant à jour Microsoft.AspNetCore.All de 2.1.0 -> 2.1.3 (SDK mis à niveau vers 2.1.401)

Vous ne savez toujours pas pourquoi cela fonctionne sur Mac mais pas sur Windows.

Mon fichier de projet API Web principal ne contenait pas Microsoft.AspNetCore.All. Je l'ai ajouté manuellement au groupe d'articles et il l'a corrigé pour moi.

Vous pouvez ajouter manuellement Connection.Abstractions dll

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