XModelBuilder eliminates boilerplate test-data builders in .NET
XModelBuilder is a new .NET library that generates fluent builders for any C# class via reflection, removing the need for hand-written test-data builders. It supports constructor parameters, init-only properties, and deep nested paths with indexers. The library includes a deterministic faker with a seeded randomizer to ensure reproducible test data.

While XModelBuilder reduces boilerplate, its reliance on reflection may raise performance concerns for large test suites, and the deterministic faker is only as good as the seed management.
