Bogus
:card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js. (by bchavez)
GenFu
GenFu is a library you can use to generate realistic test data. It is composed of several property fillers that can populate commonly named properties through reflection using an internal database of values or randomly created data. You can override any of the fillers, give GenFu hints on how to fill them. (by MisterJames)

Why I moved from AutoFixture to Bogus for test data generation for C#/xUnit tests
AutoFixture and Bogus are both well-known libraries for generating test data in C# tests. AutoFixture is, well, dated whereas Bogus is state of the art.

Effective Strategies for Writing Unit Tests with External Dependencies like Databases and APIs
Sometimes, especially when testing data-driven applications, it is important to simulate a wide variety of inputs and conditions. One of the best ways to achieve this is by using fake data generators. Tools like Faker (Python) or Bogus (C#) allow you to generate large volumes of realistic but random data. This is particularly useful when you need to test how your code handles various types of data (such as user information, addresses, or product details) without relying on real data.

ASP.NET Core Integration Testing Best Practises
For assertions inside tests, I recommend using FluentAssertions Library. And if you want to generate some fake data for your tests, I recommend using Bogus.

Bogus custom Dataset
Bogus NuGet package is fake data generator which can be helpful for populating tables in a database and testing purposes. If a database is not used and Bogus populates list of data each time an application runs, the data is random, never the same. Also, the random data generated by Bogus may not meet a developer’s requirements.

What are some alternatives?
When comparing Bogus and GenFu you can also consider the following projects:
AutoFixture - AutoFixture is an open source library for .NET designed to minimize the 'Arrange' phase of your unit tests in order to maximize maintainability. Its primary goal is to allow developers to focus on what is being tested rather than how to setup the test scenario, by making it easier to create object graphs containing test data.
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
Stryker.NET - Mutation testing for .NET core and .NET framework!
