#Changelog

*Sourced from [Moq's changelog](https://github.com/moq/moq4/blob/main/CHANGELOG.md).*

> ## 4.16.0 (2021-01-16)
>
> #### Added
>
> * Ability to directly set up the `.Result` of tasks and value tasks, which makes setup expressions more uniform by rendering dedicated async verbs like `.ReturnsAsync`, `.ThrowsAsync`, etc. unnecessary:
>
>    ```diff
>    -mock.Setup(x => x.GetFooAsync()).ReturnsAsync(foo)
>    +mock.Setup(x => x.GetFooAsync().Result).Returns(foo)
>    ```
>
>    This is useful in places where there currently aren't any such async verbs at all:
>
>    ```diff
>    -Mock.Of<X>(x => x.GetFooAsync() == Task.FromResult(foo))
>    +Mock.Of<X>(x => x.GetFooAsync().Result == foo)
>    ```
>
>    This also allows recursive setups / method chaining across async calls inside a single setup expression:
>
>    ```diff
>    -mock.Setup(x => x.GetFooAsync()).ReturnsAsync(Mock.Of<IFoo>(f => f.Bar == bar))
>    +mock.Setup(x => x.GetFooAsync().Result.Bar).Returns(bar)
>    ```
>
>    or, with only `Mock.Of`:
>
>    ```diff
>    -Mock.Of<X>(x => x.GetFooAsync() == Task.FromResult(Mock.Of<IFoo>(f => f.Bar == bar)))
>    +Mock.Of<X>(x => x.GetFooAsync().Result.Bar == bar)
>    ```
>
>    This should work in all principal setup methods (`Mock.Of`, `mock.Setup…`, `mock.Verify…`). Support in `mock.Protected()` and for custom awaitable types may be added in the future. (@stakx, [#1126](devlooped/moq#1126))
>
> #### Changed
>
> * Attempts to mark conditionals setup as verifiable are once again allowed; it turns out that forbidding it (as was done in [#997](devlooped/moq#997) for version 4.14.0) is in fact a regression. (@stakx, [#1121](devlooped/moq#1121))
>
> #### Fixed
>
> * Performance regression: Adding setups to a mock becomes slower with each setup (@CeesKaas, [#1110](devlooped/moq#1110))
>
> * Regression: `mock.Verify[All]` no longer marks invocations as verified if they were matched by conditional setups. (@Lyra2108, [#1114](devlooped/moq#1114))
