RegAsm未能使用Microsoft.Bcl.Async

Question

一個.NET 4.0組件

RegAsm使用Microsoft.Bcl.Async以下消息組件用於.NET 4.0失敗：

 
RegAsm : error RA0000 : Could not load file or assembly 
'System.Threading.Tasks, Version=1.5.11.0, Culture=neutral, 
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. 
The located assembly's manifest definition does not match 
the assembly reference. (Exception from HRESULT: 0x80131040) 

我的組件（MyAssembly.dll）使用了最新的Microsoft.Bcl.Async NuGet包，這裏的項目packages.config：

<?xml version="1.0" encoding="utf-8"?> 
<packages> 
    <package id="Microsoft.Bcl" version="1.1.6" targetFramework="net40" /> 
    <package id="Microsoft.Bcl.Async" version="1.0.165" targetFramework="net40" /> 
    <package id="Microsoft.Bcl.Build" version="1.0.13" targetFramework="net40" /> 
</packages> 

它捆綁System.Threading.Tasks.dll版本：2.6.6.0這是NuGet包的一部分。目標系統上沒有其他System.Threading.Tasks.dll（Win7與.NET 4.0，但沒有.NET 4.5），無論是在GAC還是其他地方。

這裏是MyAssembly.dll.config，它已經正確bindingRedirect元素System.Threading.Tasks：

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
    <runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
     <assemblyIdentity name="System.IO" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-2.6.6.0" newVersion="2.6.6.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
     <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-2.6.6.0" newVersion="2.6.6.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
     <assemblyIdentity name="System.Threading.Tasks" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-2.6.6.0" newVersion="2.6.6.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
    </runtime> 
</configuration> 

我的問題：不RegAsm不使用MyAssembly.dll.config？我如何使其工作，因此它可以解決bindingRedirect說明？

Answer 1

我想出瞭解決的辦法是一個黑客：

• 複製RegAsm.exe和RegAsm.exe.config從C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe到本地文件夾，其中MyAssembly.dll是;

• 編輯RegAsm.exe.config看起來像這樣：

<?xml version ="1.0"?> 
<configuration> 
    <startup useLegacyV2RuntimeActivationPolicy="true"> 
     <requiredRuntime safemode="true" imageVersion="v4.0.30319" version="v4.0.30319"/> 
     <supportedRuntime version="v4.0" sku="client" /> 
    </startup> 

    <runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
     <assemblyIdentity name="System.IO" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-2.6.6.0" newVersion="2.6.6.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
     <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-2.6.6.0" newVersion="2.6.6.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
     <assemblyIdentity name="System.Threading.Tasks" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-2.6.6.0" newVersion="2.6.6.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
    </runtime> 

</configuration> 

• 現在，運行RegAsm.exe /codebase MyAssembly.dll如預期正常工作。

有趣的是，useLegacyV2RuntimeActivationPolicy="true"已先期在標準RegAsm.exe.config，但僅靠它並沒有幫助。

我認爲這是同樣的錯誤報告在這裏：https://connect.microsoft.com/VisualStudio/feedback/details/789318/asyncpack-system-io-fileloadexception-could-not-load-file-or-assembly-system-threading-tasks-version-1-5-11-0。
