問題與PostSharp無法找到程序集system.web.mvc，版本= 3.0.0.0當沒有項目引用它

我使用PostSharp，並且這工作正常。最近，我們將一些項目升級到了MVC 5.2版。今天，我加載了一個使用MVC 4.0版本的舊項目。 PostSharp開始構建一個報告奇怪的錯誤：問題與PostSharp無法找到程序集system.web.mvc，版本= 3.0.0.0當沒有項目引用它

我經歷了所有的項目引用去了，並沒有項目，該項目引用system.web.mvc, version=3.0.0.0。所有項目都參考4.0.0.0。爲什麼提到版本3.0.0.0？它可能是從一些GAC或某些本地安裝中找到的？

如果我從項目屬性中禁用PostSharp，項目編譯成功。所以它必須是與PostSharp相關的東西。任何幫助將不勝感激，因爲我失去了約

機會是您正在使用的引用3.0的圖書館之一。一個地方，你可以檢查更多的信息是融合日誌查看器，http://msdn.microsoft.com/en-us/library/e74a18c4(v=vs.110).aspx – Phaeze 2014-10-01 17:47:54

在我的情況下，添加PostSharp NuGet直接解決問題！（v4.3.3） – 2017-05-21 20:47:53

Postpost可能是內部引用MVC 3。您可以嘗試在你的web.config綁定重定向：

<runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> 
      <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
</runtime>

這已經存在於web.config/app.config中，問題仍然存在。 – 2014-10-01 18:28:07

這個錯誤通常是提出當某些3第三方程序集的引用舊版本System.Web.Mvc的。您的web.config中有綁定重定向，但您還需要告訴PostSharp在構建期間使用該配置。您可以通過將PostSharpHostConfigurationFile構建屬性設置爲* .config文件的路徑來完成此操作。

<PropertyGroup> 
    <PostSharpHostConfigurationFile>web.config</PostSharpHostConfigurationFile> 
</PropertyGroup>

其實將這個添加到csproj文件修復了這個問題，但它確實有幫助！ – Dzoukr 2014-11-29 08:26:04

是的，它解決了我的問題，謝謝@AlexD – 2014-12-09 09:51:29

將下面的代碼添加到您的[project] .csproj文件中。要實現這個步驟如下：

右鍵單擊您的項目;
卸載項目;
然後右鍵單擊卸載的項目，然後單擊編輯[project] .csproj;
尋找PostSharp的標籤<Import Project;
然後在<Import Project .../>標記的正下方添加以下代碼;
然後重新加載項目;

代碼：

<PropertyGroup> 
    <PostSharpHostConfigurationFile>web.config</PostSharpHostConfigurationFile> 
</PropertyGroup>

XML代碼應該是這個樣子：

<Import Project="..\..\packages\PostSharp.4.0.42\tools\PostSharp.targets" Condition="Exists('..\..\packages\PostSharp.4.0.42\tools\PostSharp.targets')" /> 
<PropertyGroup> 
    <PostSharpHostConfigurationFile>web.config</PostSharpHostConfigurationFile> 
</PropertyGroup>

Upvoted因爲正確的假設，並不是每個人都會自動知道把PropertyGroup放在哪裏。謝謝你爲我節省時間。像魅力一樣工作 – MichaelCleverly 2016-07-26 11:59:56
