Moq in Asp .Net core

UPDATE on 15th October 2016:

Moq for .Net core is now available on Nuget and you can get it via below command:


It means the setting mentioned below are not required now.

UPDATE on 20th October 2016:

Moq Nuget version 4.6.38-alpha worksfor .Net core- but e.g. 4.5.3 doesn’t work, that complains that Moq 4.5.3 supports net45 and one or more packages are incompatible with .NETCoreApp V1.0.

See this post for more information.

Old Post:

I was messing around a bit for Unit testing in .Net core and I suddenly remembered about mocking, and thus I decided to use Moq which is the most popular .Net mocking framework.

After few attempts I got below error while compiling:

ASP.NET Core 5.0 error CS0246: The type or namespace name ‘Moq’ could not be found (are you missing a using directive or an assembly reference?)

After searching more on this, I wondered that Moq is not supported by .Net core!!!!!

Though I thought it is not possible as Moq is very popular among developers.

After searching more, I found that ASP.NET team from Microsoft have created a special version of Moq for internal usage.

You need to add special source to your Nuget package manager to be able to locate development version of packages by .Net team.

URL of sources where you could find this packet is here

Ok, but how to use it?

There are currently several ways to use it.

First of all Register a Moq dependencies in project.json:

"dependencies": {
        "xunit": "2.2.0-beta2-build3300",
        "dotnet-test-xunit": "2.2.0-preview2-build1029",
        "moq": "4.6.38-alpha"

Now for Nuget, you can perform any of below steps:

  • Configure a new NuGet feed to be able to reference the moq.netcore package
  • You can Create a NuGet.config file in project home directory.

If you have decided to create Nuget.config file then add below line of codes in that:

<?xml version="1.0" encoding="utf-8"?>
            <add key="AspNetVNext" value="" />
            <add key="NuGet" value="" />

And if you have decided to configure a new Nuget feed then make sure configuration matches with below configurations:


That is it!

Now you can use Moq with Asp .Net core.

Happy coding!
