Question

升级到.NET Core 2.0后，我的1.1 Web应用程序无法运行。我收到下面显示的错误消息。在检查输出后，我发现了对RZ3007错误的引用，我认为这与Razor编译器有关。视图没有编译。

Answer 1

这种方法对我有用：

删除obj和bin文件夹
运行dotnet restore
运行dotnet build

Answer 2

尝试将environment names替换为environment include之类的。

<environment include="Staging,Production">
  <strong>HostingEnvironment.EnvironmentName is Staging or Production</strong>
</environment>

根据documentation：

include属性（在ASP.NET Core 2.0中）具有与names属性类似的行为 ASP.NET Core 1.0。

<强>更新尝试使用像你.csproj这样的包来自己迁移我的一些项目（从1.1到2.0），以便重现你的错误，但遗憾的是没有运气。不确定，但可能是由预编译引起的。

我有时会CompilationFailedException，但它就像CS0246，并显示导致问题的行。但是你的RZ3007（0,0）看起来像Razor本身有点破碎。可能你应该在Github上打开新的问题。
不确定是否有帮助，但是也尝试安装Microsoft.AspNetCore.Razor.Language NuGet包，因为如果您read this discussion关于Razor更改，似乎需要它。

如果您现在不使用Visual Studio 2017，请尝试将其更新至15.3版。另外，请确保SDK已更新为2.0版

Answer 3

我最终完成了从Microsoft.详细介绍的步骤，然后我完全卸载了Visual Studio并重新安装。然后我创建了一个新的Web项目，将其设置为目标2.0，然后从非工作解决方案中复制文件，事情开始自动运行。我仍然需要确保正确配置身份验证，但事情开始变得一致。

Answer 4

从*.csproj删除下面一行，为我修复

<PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.ViewCompilation" Version="2.0.0" PrivateAssets="All" />

我在阅读了upgrade documents中的查看您的Razor View编译设置部分后添加了它。事实证明，添加它不是一个好主意！

Answer 5

在netcore-2.0之前版本的Startup类public void ConfigureServices(IServiceCollection services)方法中，需要一种解决方法：

services.AddMvc()
        .AddApplicationPart(typeof(SomeController).GetTypeInfo().Assembly)
        .AddRazorOptions(options =>
        {
            // By docs this should work out of the box, but due to a bug this workaround is needed currently:
            foreach (var name in typeof(Program).GetTypeInfo().Assembly.GetReferencedAssemblies())
                    options.AdditionalCompilationReferences.Add(MetadataReference.CreateFromFile(Assembly.Load(name).Location));
        })
        ;

但现在不行了。以下足够了：

services.AddMvc()
        .AddApplicationPart(typeof(SomeController).GetTypeInfo().Assembly);

将解决方法保留在其中会导致提到的RZ3007错误。

Answer 6

就我而言，在.csproj中禁用此Razor设置有效：

<PropertyGroup>   
<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>
...

Answer 7

在我的* csproj文件中拥有此文件

  <ItemGroup>
   <Reference Include="System.Private.Xml">
     <HintPath>C:\Program Files\dotnet\shared\Microsoft.NETCore.App\2.0.0\System.Private.Xml.dll</HintPath>
   </Reference>
 </ItemGroup>

不知道它来自哪里，但是删除它可以解决问题。

Answer 8

从 Visual Studio 2019 发布时，我选中了在目标位置删除其他文件发布选项并解决了这个问题。

错误RZ3007：目标标记名称不能为空或空格
