I have a solution with .NET Core 3.1 projects and those include test projects (xUnit). And I created a pipeline in the Azure DevOps which builds Nuget packages. And for some reason it creates packages for test projects too, even when they have

> 
> 
> ```
> <IsPackable>false</IsPackable>
> 
> ```
>

How can I exclude project from being packaged with Nuget?

The pipeline uses Windows 2019 agent, .NET Core 3.1, latest Nuget, NuGet pack and NuGet push tasks.
