Version Used: Anthony D. Green edited this page on Sep 19 2015 · 1 revision from this Repo Steps to Reproduce:

  1. The page refers to VS 2015
  2. The Example as below are marked Obsolete with VS 2017 15.5.2 
    Dim compilation As Compilation =
            VisualBasicCompilation.Create("HelloWorld").
                                   AddReferences(MetadataReference.CreateFromAssembly(
                                                     GetType(Object).Assembly)).
                                   AddSyntaxTrees(tree)

    Even when you attempt to follow the instructions to fix 

            Dim comp As Compilation = VisualBasicCompilation.Create("HelloWorld").
                                   AddReferences(MetadataReference.CreateFromFile((New Object).GetType().Assembly.Location.ToString)).
                                   AddSyntaxTrees(tree)

    You get an error

    System.BadImageFormatException: 'Could not load file or assembly 'System.IO.FileSystem, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Reference assemblies should not be loaded for execution.  They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)'

Expected Behavior: Examples work Actual Behavior: Error pointing out CreateFromAssembly is deprecated and instructions to fix are less than obvious
