Question

我正在使用PostSharp，这很好用。最近，我们将一些项目升级到MVC版本5.2。今天，我加载了一个使用MVC 4.0版本的旧项目。 PostSharp开始在构建时报告一个奇怪的错误：

Error   17  Unhandled exception (3.1.42.0, 32 bit, CLR 4.5, Release): PostSharp.Sdk.CodeModel.AssemblyLoadException: Cannot find assembly 'system.web.mvc, version=3.0.0.0, culture=neutral, publickeytoken=31bf3856ad364e35'. [Version mismatch]

我浏览了所有项目引用，并且没有引用system.web.mvc, version=3.0.0.0的项目。所有项目都参考4.0.0.0。为什么提到版本3.0.0.0？它可能是从某些GAC或某些本地安装中找到的吗？

如果我从项目属性中禁用PostSharp，项目将成功编译。所以它必须是与PostSharp相关的东西。任何帮助都会非常感激，因为我迷失了

Answer 1

当某些第三方程序集引用较旧版本的System.Web.Mvc时，通常会引发此错误。您在web.config中有绑定重定向，但您还需要告诉PostSharp在构建期间使用该配置。您可以通过将PostSharpHostConfigurationFile build属性设置为* .config文件的路径来完成此操作。

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

Answer 2

在[project] .csproj文件中添加以下代码。要实现这一目标，请遵循以下步骤：

右键单击您的项目;
卸载项目;
然后右键单击已卸载的项目，然后单击编辑[project] .csproj;
寻找PostSharp的标签<Import Project;
然后在<Import Project .../>代码正下方添加以下代码;
然后重新加载项目;

代码：

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

您的xml代码应如下所示：

<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>

Answer 3

Postsharp可能在内部引用MVC 3。您可以在web.config中尝试绑定重定向：

<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>

PostSharp的问题在没有项目引用时找不到system.web.mvc，version = 3.0.0.0的程序集
