Error RZ3007: Targeted tag name cannot be null or whitespace

Step 1: Disable precompile 

updating below property in csproj file:

<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>

Apart from this, Razor pages will be updated live.

<PropertyGroup>
<ServerGarbageCollection>false</ServerGarbageCollection>
<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>
</PropertyGroup>

特别是 WebHost.csproj

Step2: clear cache 

This method worked for me:

• delete 

  obj

   and 

  bin

   folders
• run 

  dotnet restore

• run 

  dotnet build

other:

It looks as if your project references are incorrect. You can reproduce what I'm seeing by doing the following:

1. At the command line run 

   dotnet nuget locals all -c

2. At the command line run 

   dotnet restore

3. At the command line run 

   dotnet build

最后： dotnet publish -r linux-x64
