I am getting an error as:

Could not load file or assembly 'Microsoft.Extensions.DependencyInjection, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The system cannot find the file specified.

While accessing Sitecore FakeDB in my MSTEST unit testing project.

  • Sitecore Version : 8.2 update 2
  • Sitecore FakeDB: 1.7.4
  • .Net Framework: 4.5.2

What can be the issue here?

  • Not sure how you are referencing the dll (nuget package or dll reference) in your Test project, but you can take a look at what version it is set in the Project/References.

  • Can you try to add a reference in your Test project to the Microsoft.Extensions.DependencyInjection dll or use the nuget package?

I remember having some issues with error messages not corresponding to the actual issue. If you can make sure of all of these (assuming you are following Helix principles here):

Declare databases configuration on each projects (ex : Feature/YourFeautre/App_Config/Include/Feature/Sitecore.license.config)

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <databases>
      <database id="core">
        <patch:attribute name="type">Sitecore.Data.DefaultDatabase, Sitecore.Kernel</patch:attribute>
      </database>
      <database id="master">
        <patch:attribute name="type">Sitecore.Data.DefaultDatabase, Sitecore.Kernel</patch:attribute>
      </database>
      <database id="web">
        <patch:attribute name="type">Sitecore.Data.DefaultDatabase, Sitecore.Kernel</patch:attribute>
      </database>
    </databases>
    <!-- EVENTING -->
    <eventing defaultProvider="sitecore">
      <providers>
        <clear />
        <add name="sitecore" type="Sitecore.Eventing.EventProvider, Sitecore.Kernel" systemDatabaseName="core" />
      </providers>
    </eventing>
  </sitecore>

Declare the license configuration on each projects.(ex : Feature/YourFeautre/App_Config/Include/Feature/Sitecore.license.config)

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <settings>
      <setting name="LicenseFile" value="C:\inetpub\wwwroot\yourInstance\App_Data\license.xml" />
    </settings>
  </sitecore>
</configuration>

Then in your tests, you should be using these :

using Sitecore.Data;
using Sitecore.FakeDb;
using Sitecore.Mvc.Presentation;
using Xunit;

In your projects references, you should have those : enter image description here

Official doc said you need those :

Lucene.Net.dll
Sitecore.Analytics.dll
Sitecore.Kernel.dll
Sitecore.Logging.dll
Sitecore.Nexus.dll

But I make it work without Sitecore.Analytics.dll and Sitecore.Logging.dll

After it is all said and done, make sure you are using compatible versions within your projects. I think your Microsoft.Extensions.DependencyInjection is good, would also make sure to have Microsoft.Extensions.DependencyInjection.Abstractions in your references. So within your packages.config it should look like this :

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <!-- [...your other packages...] -->
  <package id="Microsoft.Extensions.DependencyInjection" version="1.0.0" targetFramework="net452" />
  <package id="Microsoft.Extensions.DependencyInjection.Abstractions" version="1.0.0" targetFramework="net452" />
</packages>

I would also recommend to take a look at this answer : https://stackoverflow.com/questions/39802162/what-is-the-minimum-nugets-footprint-for-sitecore-fakedb-tests/39802163 because it feels like, in your similar case, you would end up using this fakedb version :

 <package id="Sitecore.FakeDb" version="1.2.2" targetFramework="net452" />

and also include sitecore.logging

<package id="Sitecore.Logging.NoReferences" version="8.2.160729" targetFramework="net452" developmentDependency="true" />

You should make sure that your Test project has at least the following references:

<packages>
  <package id="Lucene.Net" version="3.0.3" targetFramework="net452" />
  <package id="Microsoft.Extensions.DependencyInjection" version="1.0.0" targetFramework="net452" />
  <package id="Sitecore.FakeDb" version="1.7.4" targetFramework="net452" />
  <package id="Sitecore.Kernel.NoReferences" version="8.2.161221" targetFramework="net452" developmentDependency="true" />
  <package id="Sitecore.Logging.NoReferences" version="8.2.161221" targetFramework="net452" developmentDependency="true" />
  <package id="Sitecore.Nexus.NoReferences" version="8.2.161221" targetFramework="net452" developmentDependency="true" />
</packages>

You only need to add two nuget packages in your solution with the dependencies: Sitecore.Nexus and Microsoft.Extensions.DependencyInjection.
