Where do I put InternalsVisibleTo from AssemblyInfo in the new Visual Studio 2017 .csproj project file?

Just in case anyone would like to put InternalsVisibleTo within a .csproj file instead of AssemblyInfo.cs (a possible scenario is to have a naming convention between a project under test and a test project), you can do it like this:
<ItemGroup>
<AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
<_Parameter1>$(MSBuildProjectName).Test</_Parameter1>
</AssemblyAttribute>
</ItemGroup>
Having this the following code will be generated
[assembly: System.Runtime.CompilerServices.InternalsVisibleTo("MyProject.Test")]
inside auto-generated AssemblyInfo.cs (e.g. for Debug configuration and .NET Standard 2.0 target)
/obj/Debug/netstandard2.0/MyProject.AssemblyInfo.cs
Additional Info
In case you're on .NET Core 3.1 and this approach isn't working, you may have to explicitly generate assembly info by adding the following to your .csproj file:
<PropertyGroup>
<!-- Explicitly generate Assembly Info -->
<GenerateAssemblyInfo>true</GenerateAssemblyInfo>
</PropertyGroup>
As of .NET 5 (and newer .NET versions) this actually works once added to your csproj:
<ItemGroup>
<InternalsVisibleTo Include="YourProject.Tests.Unit" />
</ItemGroup>
Work and discussion around this feature can be seen on this PR on dotnet's GitHub repo.
To clarify Hans Passant's comment above, you simply have to add InternalsVisibleTo to any cs file in your project. For example, I created an AssemblyInfo.cs file in the root of the project and then added the following content (only):
using System.Runtime.CompilerServices;
[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2, PublicKey=<ADD_KEY_HERE>")]
