Since you have added Service4 class library reference only in .NET 4.0 dependencies section (refer below snapshot), You need to use Conditional Compilation.

NET40 dependencies

To access, Service4 members, you need to do like this-

#if NET40 
    Service4.Test.PrintHi(); 
#endif

These are list of preprocessor symbols used in #if directives:

.NET Framework 2.0 --> NET20

.NET Framework 3.5 --> NET35

.NET Framework 4.0 --> NET40

.NET Framework 4.5 --> NET45

.NET Framework 4.5.1 --> NET451

.NET Framework 4.5.2 --> NET452

.NET Framework 4.6 --> NET46

.NET Framework 4.6.1 --> NET461

.NET Framework 4.6.2 --> NET462

.NET Standard 1.0 --> NETSTANDARD1_0

.NET Standard 1.1 --> NETSTANDARD1_1

.NET Standard 1.2 --> NETSTANDARD1_2

.NET Standard 1.3 --> NETSTANDARD1_3

.NET Standard 1.4 --> NETSTANDARD1_4

.NET Standard 1.5 --> NETSTANDARD1_5

.NET Standard 1.6 --> NETSTANDARD1_6
