GodSharp.FluentMember

Get Started

• Install Package

  <ItemGroup>
    <PackageReference Include="GodSharp.FluentMember" Version="2021.206.26" />
  </ItemGroup>

• Add Attribute

  [FluentMemberGenerator(Partial = true)]
  public partial class User
  {
      public int Id { get; internal set; }
      public int Age { get; set; }
      internal string Name { get; set; }
      public string Secret { get; private set; }
      public Role Role { get; set; } = new();
  
      [FluentMemberGenerator(Partial = true)]
      public partial struct Address
      {
          public string Country { get; set; }
          public string City { get; set; }
          internal string Postcode { get; set; }
          public string Secret { get; private set; }
      }
  }

• Build Project

  You will be use fluent api to set member, like With* and Set method by extension method.
