当目标为System.Net.Http 4.7.2时，引用.NET的正确方法是什么？

Question

我有一个解决方案，其中包含了一些web应用程序，所以在构建过程中AspNetCompiler任务正在运行。还提供了：

• VS 2017
• 命令行上使用/err开关调用msbuild，即将警告提升为错误。

在从头构建代码时，我得到以下错误(可能是升级警告，我不在乎)：

我们所有的项目都像这样引用System.Net.Http：

<Reference Include="System.Net.Http" />

没有任何项目在其app.config或web.config文件中对此程序集进行绑定重定向。

所有项目的目标都是.NET框架4.7.2，但一些第三方依赖项是.NET标准。

总之，我在网上搜索过：

1. 有些人声称引用System.Net.Http应该只从NuGet中进行，有些人则说相反。
2. 有些人声称绑定重定向是必要的，而另一些则相反。
3. 有人说这个问题是用.NET框架4.7.2解决的(显然不是)

我也知道：

• GAC包含System.Net.Http.dll和4.0.0.0的组装版本以及4.7.3190.0 built by: NET472REL1LAST_C的文件版本。由此我得出结论，它与.NET 4.7.2相对应
• 另一方面，在编译过程中，msbuild解析对c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.7.2\System.Net.Http.dll的引用，该引用具有4.2.0.0的组装版本和4.7.3062.0 built by: NET472REL1的文件版本。

现在我很困惑。参考程序集中的System.Net.Http.dll文件版本表明它比GAC的版本要老，但是它的程序集版本是4.2.0.0？如何在运行时在GAC中有4.0.0.0版本的机器上解决这个依赖关系？检查参考程序集是否有较早的.NET版本(如3.7.1及更低版本)，显示了装配版本为4.0.0.0的System.Net.Http.dll，因此在.NET框架4.7.2中引入了这种混乱。

那么，我如何使这该死的东西编译干净呢？另外，我不明白为什么只有AspNetCompiler会抱怨。如何才能彻底排除故障呢？二进制日志似乎对AspNetCompiler错误没有一点帮助。

Answer 1

到目前为止，我只找到了一种方法来解决这个问题。我们必须使用.net框架4.7.2来处理Chromium需求。似乎有几个站点记录了这一点，但是由于大量的Microsoft.Owin依赖问题，我们无法访问NuGet 4.x。下面的一些信息是关于SameSite修复的，但是我在.net框架4.7.2中的System.Net.Http程序集中遇到了很多困难，所以下面也是如此。

我发现，如果您将MVC和Web.Api项目带到.net框架4.7.2，那么确保所有使用System.Net.Http的项目都引用了GAC4.2.0.0版本。我有类库项目也运行Web.api控制器。我还在GAC版本旁边安装了NuGet System.Net.Http。您可能必须编辑您的项目文件以同时引用两者。项目文件中的NuGet程序集引用应该包括一个ExcludeAssets元素。最后，示例排除资产我将我的非主项目web.api类库项目转换为使用PackageReference而不是packages.config。我认为这是使用excludeAssets所必需的。

我还使用nuget包管理器控制台重新安装所有nuget软件包，以达到4.7.2的目标框架。将NuGet包重新安装到重新目标框架4.7.2

您的主项目web.config应该而不是为System.Net.Http定义一个运行时dependentAssembly部分。需要排除它，以便自动选择它。我所做的其他类库项目包括对dependentAssembly版本4.2.0.0的System.Net.Http引用。我还将程序集定义和运行时dependentAssembly添加到我的视图、web.config和我所在区域内的所有视图web.config文件中。我不知道这有多必要。

我用这个网站来帮助写一个曲奇重写器。我发现这只负责system.web cookie，而不是OWIN。相同站点的Cookie重写器

我无法访问4.xowin补丁来将SameSite属性添加到OWIN中，但我找到了一种方法，即通过将SystemWebCookieManager添加到OWIN选项中，系统将自动为您完成此操作。SameSiteCookieManager
