Q:

Is there any replace of AssemblyBuilder.DefineDynamicAssembly in .NET Core?

How to port the following code to .Net Core:
AppDomain.CurrentDomain.DefineDynamicAssembly(
                new AssemblyName(
                    Guid.NewGuid().ToString()),
                    AssemblyBuilderAccess.RunAndSave);

Is it possible?

A:

add this to your project.json
 "dependencies": {
    "System.Reflection.Emit": "4.0.1"
  },

and use 
AssemblyBuilder.DefineDynamicAssembly(new AssemblyName(Guid.NewGuid().ToString()),
            AssemblyBuilderAccess.Run);

AssemblyBuilderAccess.RunAndSave is not supported at the moment link to souce.
Update:
For new .csproj projects use:
<ItemGroup>
  <PackageReference Include="System.Reflection.Emit" Version="4.3.0" />
</ItemGroup>
