安装Microsoft.ReportingServices.ReportViewerControl.WebForms

Question

我在现有的MVC项目中升级到 ReportViewer 14.0 之后，我遇到了无法解决（或理解）的程序集冲突。

  

警告发现同一依赖程序集的不同版本之间存在冲突。       在Visual Studio中，双击此警告（或选择它并按Enter键）以修复冲突;否则，将以下绑定重定向添加到       应用程序配置文件中的“runtime”节点：                       NRM C：\ Program Files（x86）\ Microsoft Visual Studio \ 2017 \ Community \ MSBuild \ 15.0 \ Bin \ Microsoft.Common.CurrentVersion.targets 1964

它还说：

  

无法解决之间的冲突   “Microsoft.Build.Framework，Version = 14.0.0.0 ，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a”和   “Microsoft.Build.Framework，Version = 4.0.0.0 ，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a”。

如果我双击错误消息（如上所述），则将这些行添加到Web.Config：

<dependentAssembly>
   <assemblyIdentity name="Microsoft.Build.Framework" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
   <bindingRedirect oldVersion="0.0.0.0-14.0.0.0" newVersion="14.0.0.0"/>
</dependentAssembly>

但这会在运行时创建此错误：

  

无法加载文件或程序集'Microsoft.Build.Framework，   Version = 4.0.0.0 ，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'或   其中一个依赖项。系统找不到指定的文件。

如果我删除了Web.Config中的bindingRedirect，我只有警告但所有（包括ReportViewer 14.0）都能正常工作。

当我将Build-out更改为Diagnostic时，我会收到以下额外信息：

在诊断日志中，还提到了以下冲突：

• System.Net
• Microsoft.Build.Framework
• mscorlib程序
• System.Core程序
• 系统

Answer 1

我今天又得到了错误。

当我通过NuGet添加ReportViewer时，我手动添加了这些引用。我清除了手动参考，但这并没有清除Web.Config。在这个过程中，我还更新了可能与它有关的其他软件包。

我通过从Web.Config中清除这些行来解决了这个问题。
