JetBrains Rider 无法识别属性生成的构造函数

Question

[AutoConstructor] in the code below will automatically generate a constructor (as shown in the figure below):

It works fine in Visual Studio, but JetBrains Rider has an error message:

I do not understand. . .

(Because I am not good at English, I am using Google Translate to ask questions, please forgive me)

using System;
using System.Linq;
using ComputeSharp;

namespace ComputeSharpTest
{
    class Program
    {
        static void Main(string[] args)
        {
            // Allocate a writeable buffer on the GPU, with the contents of the array
            // Get some sample data
            int[] array = Enumerable.Range(1, 1000000).ToArray();

            // Allocate a GPU buffer and copy the data to it.
            // We want the shader to modify the items in-place, so we
            // can allocate a single read-write buffer to work on.
            using ReadWriteBuffer<int> buffer = Gpu.Default.AllocateReadWriteBuffer(array);
            
            // Launch the shader
            Gpu.Default.For(buffer.Length, new MultiplyByTwo(buffer));

            // Get the data back
            buffer.CopyTo(array);
        }
    }

    [AutoConstructor]
    public readonly partial struct MultiplyByTwo : IComputeShader
    {
        public readonly ReadWriteBuffer<int> buffer;

        public void Execute()
        {
            buffer[ThreadIds.X] *= 2;
        }
    }

}

As per https://github.com/Sergio0694/ComputeSharp/issues/116 (and also https://github.com/Sergio0694/ComputeSharp#requirements ):

In order to work correctly, ComputeSharp also needs the source generator to be added to consuming projects as an analyzer, so that it can run when the code is being compiled.

You can do so by adding the following code to your .csproj file, just like in the sample projects:

<ItemGroup>
    <ProjectReference Include="..\..\src\ComputeSharp\ComputeSharp.csproj" />
    <ProjectReference Include="..\..\src\ComputeSharp.SourceGenerators\ComputeSharp.SourceGenerators.csproj"
                      OutputItemType="Analyzer"
                      ReferenceOutputAssembly="false"
                      PrivateAssets="contentfiles;build" />
  </ItemGroup>

Additionally, you need to ensure you are using .NET 5 (not an early version of .NET Framework / Core).

If your issue persists, you may also wish to try using VS 2019 rather than Rider.
