错误 RZ3007:目标标记名称不能为空或空格

Error RZ3007: Targeted tag name cannot be null or whitespace

升级到 .NET Core 2.0 后,我的 1.1 Web 应用程序无法 运行。我收到如下所示的错误消息。检查输出后,我发现了对 RZ3007 错误的引用,我认为它与 Razor 编译器有关。视图未编译。

尝试用environment include替换environment names

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

根据documentation

The include property (in ASP.NET Core 2.0) has a similar behavior of the names attribute in ASP.NET Core 1.0.

更新: 尝试使用你 .csproj 中的软件包自己迁移我的一些项目(从 1.1 到 2.0)以重现你的错误,但不幸的是没有运气。不确定,但可能是预编译造成的。

我有时 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 本身以某种方式坏掉了。也许你应该在 Github 上打开新问题。
不确定是否有帮助,但请尝试安装 Microsoft.AspNetCore.Razor.Language NuGet 包,因为如果您 read this discussion 关于 Razor 更改,似乎需要它。

如果您现在不使用它,也请尝试将 Visual Studio 2017 更新到版本 15.3。 另外,请确保 SDK 已更新到版本 2.0

我最终完成了 Microsoft. 中详述的步骤,然后完全卸载 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,然后从无法正常工作的解决方案中复制了文件,一切都自动开始工作了。我仍然需要确保身份验证配置正确,但一切都开始正常了。

*.csproj 中删除下面的行为我修复了它

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

我是在阅读 查看 upgrade documents 中的 查看您的 Razor View 编译设置 部分后添加的。事实证明添加它不是一个好主意!

这个方法对我有用:

  • 删除 objbin 个文件夹
  • 运行 dotnet restore
  • 运行 dotnet build

Startup class public void ConfigureServices(IServiceCollection services) pre-netcore-2.0 版本的方法中需要一个解决方法:

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));
        })
        ;

但现在不是了。以下就够了:

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

保留解决方法会导致提到的 RZ3007 错误。

在我的例子中,禁用此 Razor 设置 in.csproj 有效:

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

我的 *csproj 文件中有这个:

  <ItemGroup>
   <Reference Include="System.Private.Xml">
     <HintPath>C:\Program Files\dotnet\shared\Microsoft.NETCore.App.0.0\System.Private.Xml.dll</HintPath>
   </Reference>
 </ItemGroup>

不知道它来自哪里,但删除它解决了问题。

从 visual studio 2019 年发布时,我检查了 Remove additional files at destination 发布选项,这解决了这个问题。
