Could not load file or assembly Moq, Version=4.8.0.0 when used with higher version of Moq

[ddimkovikj]

Getting the following exception when trying to use this package with Moq 4.16.1:

---- System.IO.FileLoadException : Could not load file or assembly 'Moq, Version=4.8.0.0, Culture=neutral, PublicKeyToken=69f491c39445e920' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Stack Trace: 
<test_method_clientAsync>d__7.MoveNext()
AsyncTaskMethodBuilder.Start[TStateMachine](TStateMachine& stateMachine)
TestName.TestMethodNameAsync()

Binding redirects didn't help either, getting:

System.IO.FileLoadException : Could not load file or assembly 'Moq, Version=4.16.1.0`

Does anyone have a fix for this?

I tried to reproduced your issue but without success. At least with csproj files based on Net.SDK that manage binding redirects automatically.

If you still use legacy csproj format and packages.config files to reference NuGet packages, then you may need to manually manage binding redirects (even if the User Interface of Visual Studio often do it correctly for you when installing NuGet packages with it)
But in that case, pay attention that those bindings are based on the assembly versions and not the NuGet packages versions. Even if packages authors often sync that both numbers it's not always the case, and this can be your issue here since Moq authors seems to never change the patch version on the assemblies distributed in their packages. So Moq packages 4.16.0 and 4.16.1 both contains assemblies using the same version number, aka 4.16.0.0

So maybe you should try to write your binding with 4.16.0.0 as the new version and not 4.16.1.0
