I think I experienced same behavior. Try to build your solution so that VS can discover your tests. Otherwise please share you tests csproj file to ensure you reference correct packages. Mine is: 

<pre><code>&lt;Project Sdk="Microsoft.NET.Sdk"&gt;

 &lt;PropertyGroup&gt;
 &lt;OutputType&gt;Exe&lt;/OutputType&gt;
 &lt;TargetFramework&gt;netcoreapp1.1&lt;/TargetFramework&gt;
 &lt;/PropertyGroup&gt;

 &lt;ItemGroup&gt;
 &lt;PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" /&gt;
 &lt;PackageReference Include="xunit" Version="2.2.0" /&gt;
 &lt;PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" /&gt;
 &lt;/ItemGroup&gt;

&lt;/Project&gt;
</code></pre>

UPDATE: I have played around a bit and it looks like VS cannot find the tests without <code>&lt;OutputType&gt;Exe&lt;/OutputType&gt;</code>

UPDATE 2: Try also add following to csproj as I see VS adds in in some cases.

<pre><code>&lt;ItemGroup&gt;
 &lt;Service Include="{82a7f48d-3b50-4b1e-b82e-3ada8210c358}" /&gt;
&lt;/ItemGroup&gt;
</code></pre>

I hit this issue with VS 2017 not discovering MSTest unit tests on .NET Core.

The Tests output only reported that it had discovered zero tests.

On running <code>dotnet test MyProject.csproj -t</code> in a command prompt, it advised that I did not have the correct .NET Core runtime installed to match the project's RuntimeFrameworkVersion.

Installing the latest VS 2017 update and .NET Core runtime resolved the issue.

blocks|key|107471|text|在从project.json迁移到csproj之后，我也遇到了同样的问题。并通过移除net451目标框架，只留下netcoreapp1.1来解决这个问题。现在它工作得很完美，而且每次都会被发现。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|107472|当然，如果你需要很多框架目标，你不应该这样做，只需要使用CLI来测试它们……|107473|entityMap^0|2|C|H|6|16|6|1K|D|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|S|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|I|$]]

I had the same issue after migration from <code>project.json</code> to <code>csproj</code>. 
And resolved it by removing <code>net451</code> target framework and leave only <code>netcoreapp1.1</code>. Now it's works perfect and discover every time. 

Of course if you need many framework targets you shouldn't do it, just use CLI to test them...

It may due to inconsistent project settings for Processor Architecture. The Test project target must match the test default Processor Architecture.

I also had this issue and it was remedied by ensuring my project and test project had the same target framework version in the .csproj file

blocks|key|105439|text|另外，当有多个测试项目和相同的输出目录时，还要确保*.csproj文件中没有混合PackageReference版本，并且还要更新测试项目的包，尤其是MSTest.TestAdapter以及MSTest.TestFramework|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|105440|entityMap^0|12|K|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Also make sure you don't have mixed PackageReference versions in the *.csproj files when having multiple test projects and the same output directory and also update the packages of test project especially MSTest.TestAdapter as well as MSTest.TestFramework

can anyone help me get VS2017 to work with .NET Core test projects? 

I tried creating both MSTest and xUnit unit test projects for .NET Core from the VS 2017 templates. Neither of them works in the test explorer (not discovered), however running <code>dotnet test</code> from the project folder works fine.

Steps to reproduce:

<ol>
<li>Create new project in VS 2017</li>
<li>Choose either the <code>Unit Test Project (.NET Core)</code> or <code>xUnit Test Project (.NET Core)</code> template</li>
<li>Implement some arbitrary unit test</li>
<li>Build the solution</li>
<li>Go to the text explorer and try to <code>Run All</code> </li>
</ol>

At this point the Output window should tell you that 0 test were discovered

<code>.csproj</code> file:

<pre><code>&lt;Project Sdk="Microsoft.NET.Sdk"&gt;

 &lt;PropertyGroup&gt;
 &lt;TargetFramework&gt;netcoreapp1.1&lt;/TargetFramework&gt;
 &lt;/PropertyGroup&gt;

 &lt;ItemGroup&gt;
 &lt;PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" /&gt;
 &lt;PackageReference Include="xunit" Version="2.2.0" /&gt;
 &lt;PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" /&gt;
 &lt;/ItemGroup&gt;

&lt;/Project&gt;
</code></pre>

If I tried to create a MSTest unit test project from the template that targets .NET Framework (full, not .NET Core), it worked.

Any ideas?
