Strawberry Shake: Code generation fails when GraphQL field names conflict with System.Object method names

[karlssberg]

Product

Strawberry Shake

Version

15.1.11

Link to minimal reproduction

https://github.com/karlssberg/strawberry-shake-bug

Steps to reproduce

1. Create a GraphQL schema with a type containing a field named equals:

type StringMatch {
  equals: String
}

2. Generate Strawberry Shake client code
3. Attempt to build the project

What is expected?

The code generator should detect C# reserved method names and either:

• Automatically suffix the property name (e.g., Equals → EqualsValue or Equals_)
• Provide a configuration option to customize property naming

What is actually happening?

Generated code creates a property named Equals which conflicts with System.Object.Equals(object), causing compilation errors:

error CS0102: The type 'StringMatch' already contains a definition for 'Equals'

Additional context

Also affects input declarations that contain fields matching System.Object method names.
