Problem on the basic usage.

Hi, I’ve tried to use the basic usage on my machine with SDK .net 6.0.100, but I cannot compile due to the following errors:

• Program.cs(13, 2): [CS0246] The type or namespace name ‘UnionAttribute’ could not be found (are you missing a using directive or an assembly reference?);
• Program.cs(13, 2): [CS0246] The type or namespace name ‘Union’ could not be found (are you missing a using directive or an assembly reference?);

This is my cproj and my Program.cs:

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

<PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
</PropertyGroup>

<ItemGroup>
  <PackageReference Include="Dunet" Version="1.0.0" />
</ItemGroup>

</Project>`

`using Dunet;

var shape = new Shape.Rectangle(3, 4); var area = shape.Match( circle => 3.14 * circle.Radius * circle.Radius, rectangle => rectangle.Length * rectangle.Width, triangle => triangle.Base * triangle.Height / 2 ); Console.WriteLine(area);

[Union] partial record Shape { partial record Circle(double Radius); partial record Rectangle(double Length, double Width); partial record Triangle(double Base, double Height); }`

What I’m missing?

Like a dumb, I’ve forgotten to have set SDK 7-preview as default (and global.json did not affect rider build). I’ve set default SDK 6.0.301, and all worked properly.

Thank you for the support, and I’m sorry I wasted your time.

No worries. Glad you got it working!
