Targeting .Net Framework 4.5 and .Net Standard libraries

Question

I have a .NET library ( Products.SDK) that should be compatible with both the .NET Framework 4.5 and the .NET Standard 1.4.

(Later I will also create a NuGet package from this library)

My question is:

How to write code in this library? Given that both structures use different libraries / dependencies?

• Will I have two separate projects with the same solution?

  Products.SDK.sln

  • Products.SDK.NetFramework
  • Products.SDK.NetStandard

• Will I have only one project and use preprocessor directives #ifto define different classes inside the library?

  namespace Products.SDK
  {
      #if NETSTANDARD1_3
          public class ProductsApi
          {
              public string ApiUrl { get; set; }
          }
      #else
          public class ProductsApi
          {
              public string ApiUrl { get; set; }
          }
      #endif
  }
  

If parameter # 1 is correct, how can I make sure both projects are compiled using the same name / namespace ( Products.SDK)
