A C# source generator that automatically generates static Get and With methods for public properties in classes, structs, or records marked with the [GeneratePropertyMethods] attribute. This simplifies property access and functional-style updates, especially for immutable records.

• Generates static Get{PropertyName} methods for public properties with public getters.
• Generates static With{PropertyName} methods for public properties with public setters.

Install the NuGet package:

dotnet add package PropertyMethods.SourceGeneration

1. Mark a type with the attribute:

   using PropertyMethods;
   
   [GeneratePropertyMethods]
   public partial record Person(string Name, int Age)

2. Generated code:

   namespace YourNamespace;
   
   public partial record Person
   {
       public static string GetName(Person person) => person.Name;
       public static Person WithName(Person person, string name) => person with { Name = name };
       public static int GetAge(Person person) => person.Age;
       public static Person WithAge(Person person, int age) => person with { Age = age };
   }

3. Use the methods:

   var person = new Person { Name = "Alice", Age = 30 };
   Console.WriteLine(Person.GetName(person)); // Outputs: Alice
   var updated = Person.WithName(person, "Bob");
   Console.WriteLine(Person.GetName(updated)); // Outputs: Bob

• Target type must be public, partial, and non-static.
• Properties must have public getters (for Get methods) or setters (for With methods).
• Compatible with .NET Standard 2.0 and above.

1. Create a .NET project (e.g., console, library).
2. Install the package:

   dotnet add package PropertyMethods.SourceGeneration

3. Add the [GeneratePropertyMethods] attribute to a public partial type.
4. Build to generate the methods.
