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)
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. (by AutoFixture)

API: Go, .NET, Rust
Yes, it does feel like some of the "standard stuff" in other more nuanced languages are missing (especially miss AutoFixture ngl). Some of those are a conscious decison by the golang team for example.

Integration Testing Postgres Store
Our first test is very easy, I like to name my tests as MethodName_GivenCondition_ShouldExpectedResult to follow the pattern, I have added GetById_GivenRecordDoesNotExist_ShouldReturnNull and I am going to leavarage excellent AutoFixture to get a new Guid as parameter. For this test we don't need arrange part, we would skip to the act and then assert. For Assertion I am going to use FluentAssertions. For this test we need to assert the returned result is null.

Setting up a simple testing project with C#
The next test to talk about, is that if this was a bank, we would have multiple customers, who can hold multiple accounts that we need to calculate the interest for. You could manually construct these objects if you want, but I'm going to use a package called AutoFixture to make life easier.

AutoFixture Tips and Tricks
AutoFixture is an amazing library that simplifies the process of creating test data in .NET. If for some reason you don't use this fantastic tool, it's time to consider it. Today, I'm going to share some tips for using AutoFixture that will be beneficial for developers of all skill levels. Let's get started!
- Integration tests without API dependencies with ASP.NET Core and WireMock.Net

Reduce your tests cognitive complexity with AutoFixture
Ensuring that your test is still readable and not bloated by the setup of those variables may be quite a challenge but hopefully no more with AutoFixture, let's see how!

14 .NET packages I always recommend
First time I heard of Bogus, looks interesting, been using AutoFixture for those will definitely take a look at it.
- LPT: There is a library called Bogus, you should know it exists much earlier than I did in my career.
What are some alternatives?
When comparing GenFu and AutoFixture you can also consider the following projects:
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
NSubstitute - A friendly substitute for .NET mocking libraries.
FsCheck - Random Testing for .NET
FakeItEasy - The easy mocking library for .NET
Stryker.NET - Mutation testing for .NET core and .NET framework!
NBomber - Modern and flexible load testing framework for Pull and Push scenarios, designed to test any system regardless a protocol (HTTP/WebSockets/AMQP etc) or a semantic model (Pull/Push).
NBuilder - Rapid generation of test objects in .NET
