Multiple assemblies with equivalent identity error

My unit test projects had this error:

Multiple assemblies with equivalent identity have been imported: '<in-memory assembly>' and '<in-memory assembly>'

This blog suggested moving System.* references down to framework specific section, I found removing them entirely also worked.

TagBuilders

One can no longer use TagBuilder.ToString() to get HTML but instead must make use of the IHtmlContent that it implements. See TagBuilder InnerHtml in ASP.NET 5 MVC 6

Entity Framework

• New syntax for migrations: dnx ef migrations add MyMigration and dnx ef database update

Other

• Further fixes may be found on the ASP.NET announcements repo
• Feel free to edit in your own findings
