NET Core 3.0.0 - incorrect embedded resource name if resource and code files differ only by extension

NET Core 3.0.0 - incorrect embedded resource name if resource and code file names differ only by extension in the same folder

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <EmbeddedResource Include="MyCsFile.xml" />
  </ItemGroup>

</Project>

// in file MyCsFile.cs
namespace NetConsoleApp1
{
    public class FirstClassInTheCsFile
    {
    }
}

// Program.cs
using System;

namespace NetConsoleApp1
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            Console.WriteLine(typeof(FirstClassInTheCsFile).Assembly.GetManifestResourceNames()[0]);
        }
    }
}

Output:

NetConsoleApp1.FirstClassInTheCsFile

Expected:

NetConsoleApp1.MyCsFile.xml

Observed: after cs file or xml file name has been changed just starting the app in debug mode does not build the change into the binaries. Rebuild does.

@JasonCard, could you please help redirect?

Hi @jamshedd, I work on .NET content localization, so I think you may have pinged the wrong person?

This is a known issue with resources in the 3.0 SDK

[dasMulli]

See dotnet/msbuild#4740

The known issue document describes this at https://github.com/dotnet/core/blob/master/release-notes/3.0/3.0-known-issues.md#preview-9.

You basically need to set

<PropertyGroup>
    <EmbeddedResourceUseDependentUponConvention>false</EmbeddedResourceUseDependentUponConvention>
</PropertyGroup>

in the project file
