Error RZ3007: target tag name cannot be blank or white space

Question

Error RZ3007: target tag name cannot be blank or white space

After upgrading to .NET Core 2.0, my 1.1 application cannot work. I get the error message below. After checking the output, I found links to the RZ3007 error, which, it seems to me, is related to the Razor compiler. View does not compile.

Home / Index.cshtml:

@model LayoutViewModel <div></div>

Views / Shared / _Layout.cshtml

  <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>@ViewData["Title"] - GLCoderConfiguration</title> <environment names="Development"> <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" /> <link rel="stylesheet" href="~/css/site.css?" /> </environment> <environment names="Staging,Production"> <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/css/bootstrap.min.css" asp-fallback-href="~/lib/bootstrap/dist/css/bootstrap.min.css" asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" /> <link rel="stylesheet" href="~/css/site.min.css?" asp-append-version="true" /> </environment> </head> <body> <nav class="navbar navbar-default navbar-form " > <div class="navbar-header" style="margin-top:10px;margin-bottom:15px;"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">SCM - NCMain</a> </div> <div class="collapse navbar-collapse vcenter" id="bs-example-navbar-collapse-1" style="margin-top:10px;margin-bottom:0px;"> </div> </nav> <div class="container body-content"> @RenderBody() <hr /> <footer> <p>&copy; 2017 - England Logisitics - SCM</p> </footer> </div> <environment names="Development"> <script src="~/lib/jquery/dist/jquery.js"></script> <script src="~/lib/bootstrap/dist/js/bootstrap.js"></script> <script src="~/js/site.js" asp-append-version="true"></script> </environment> <environment names="Staging,Production"> <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-2.2.0.min.js" asp-fallback-src="~/lib/jquery/dist/jquery.min.js" asp-fallback-test="window.jQuery" crossorigin="anonymous" integrity="sha384-K+ctZQ+LL8q6tP7I94W+qzQsfRV2a+AfHIi9k8z8l9ggpc8X+Ytst4yBo/hH+8Fk"> </script> <script src="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/bootstrap.min.js" asp-fallback-src="~/lib/bootstrap/dist/js/bootstrap.min.js" asp-fallback-test="window.jQuery && window.jQuery.fn && window.jQuery.fn.modal" crossorigin="anonymous" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa"> </script> <script src="~/js/site.min.js" asp-append-version="true"></script> </environment> @RenderSection("Scripts", required: false) </body> </html>

I had several presentation components (LoginStatus and MenuItems), but removed them to try to get this to work.

This method worked for me:

remove obj and bin
run dotnet restore
run dotnet build

Try replacing environment names with environment include .

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

According to the documentation :

The include property (in ASP.NET Core 2.0) has the same behavior for the names attribute in ASP.NET Core 1.0.

UPDATE: I tried to migrate some of my projects (from 1.1 to 2.0) using packages like you .csproj to reproduce your error, but, unfortunately, no luck. Not sure, but maybe it's caused by precompilation.

I sometimes had a CompilationFailedException , but it was like CS0246 and showed the lines that caused the problem. But your RZ3007 (0,0) looks like the Razor itself somehow broke. You should probably open the new version on Github.
Not sure if that helps, but try installing the Microsoft.AspNetCore.Razor.Language NuGet package because it seems necessary if you read this discussion about Razor changes.

Also try upgrading Visual Studio 2017 to version 15.3 if you are not using it now. Also, make sure the SDK is updated to version 2.0.

In the end, I went through the steps described at Microsoft. Then I completely uninstalled Visual Studio and reinstalled. Then I created a new web project, configured it to target 2.0, and then copied the files from a non-working solution, and everything began to work automatically. I still need to make sure that authentication is configured correctly, but everything starts to fall in line.

Removing line below from *.csproj fixed for me

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

I added it after reading the section "Settings for your Razor View compilation" in updating documents . Turns out it would be nice to add it!

In the Startup class public void ConfigureServices(IServiceCollection services) method in pre-netcore-2.0 versions, a workaround is needed:

 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)); }) ;

But no more. Enough:

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

Leaving a workaround in the causes of the mentioned error RZ3007.

In my case, disabling this Razor installation in .csproj worked:

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

Meelstorm · Answer 7 · 2019-01-29T14:52:06+0000

This was in my * csproj file:

  <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>

I have no idea where it came from, but eliminating it solved the problem.
