Run .NetCore 2.0 test from command line

[nbns]

I have two prjects my library and test.
The test library contains only a simple test and reference to my library

    [TestFixture]
    class Class1
    {
        [Test]
        public void simple_test_false()
        {
            Assert.IsFalse(false, "false");
        }
    }

Nuget packages installed for the test project:

• nunit" Version="3.10.1"
• NUnit3TestAdapter "3.10.0"
• Microsoft.NET.Test.Sdk 15.8.0"

dotnet verion 2.1.400

Running test from Visual Studio Test Explorer (2017), everything works fine, but when I running its from console I have the following output:

Build started, please wait...

How to get rid of this error?

Sorry for my English.

Hi @b7ns
Can you provide the exact command you use to run the tests. Currently, I only see the output. That being said it looks like an error in dotnet test (see microsoft/vstest#1129).

@b7ns are your tests multi-targeted? The Test run for d:\dev\testlib\src\testlib\bin\Debug\netstandard2.0\TestLib.dll(.NETStandard,Version=v2.0) seems odd. Tests must target .NET Core or full framework. Can you copy in the CSPROJ file you are using?

Thanks @mikkelbu
It's my fault.
Yes, I ran the test command in the solution folder. When I run in the test folder, It's all right.

Note that it says

Test run for d:\dev\testlib\src\testlib\bin\Debug\netstandard2.0\TestLib.dll(.NETStandard,Version=v2.0)
...
Test run for d:\dev\testlib\test\TestLib.Test\bin\Debug\netcoreapp2.0\TestLib.Test.dll(.NETCoreApp,Version=v2.0)

so my guess was that TestLib.dll is the production assembly and TestLib.Test.dll the test assembly.
