Does FluentAssertions support Test projects that are .NET Core 2.0?

I have a Class Library (.NET Core 2.0) being tested by an MSTest Test Project (.NET Core 2.0). The FluentAssertions site says .NET Core 2.0 is supported (and I stepped down from 2.1). It works locally, but on the build machine I get the following error:

The nuget command failed with exit code(1) and error(Errors in D:\a\1\s\ProjectName.Tests.csproj Package System.Configuration.ConfigurationManager 4.4.0 is not compatible with netcoreapp2.0 (.NETCoreApp,Version=v2.0). Package System.Configuration.ConfigurationManager 4.4.0 supports: - net461 (.NETFramework,Version=v4.6.1) - netstandard2.0 (.NETStandard,Version=v2.0) One or more packages are incompatible with .NETCoreApp,Version=v2.0.)

I'm pretty sure .NET Core 2.0 implemented .NETStandard 2.0 so should work... – Michal Ciechan
Also that error is pointing at System.Configuration.ConfigurationManager – Michal Ciechan
Personally would try the following (as it looks like there is some incorrect dependency finding): stackoverflow.com/a/39833423/271106 – Michal Ciechan
Under Dependencies > NuGet > FluentAssertions (5.4.2) there are two items - FluentAssertions.dll and System.Configuration.ConfigurationManager (4.4.0). And in the NuGet UI under Dependencies for FluentAssertions it shows .NETCoreApp, Version=v2.0 it has one - System.Configuration.ConfigurationManager (>=4.4.0) – KarlZ
Also have you tried Cleaning out your source on your build server? – Michal Ciechan

The issue was that the Azure DevOps Build pipeline was using NuGet 4.1.0. I added a task to the pipeline right before the NuGet restore called NuGet Tool Installer and set it to install version 4.4.0. Then everything worked fine. Thanks Dennis Doomen!
