Powershell Tools 1.1.0-preview4 fails when target >=net452

Steps to reproduce

• Create a Web API site.
• In project.json, set ‘frameworks’ to just ‘net462’ and update all packages to version ‘1.1.0’

"dependencies": {    
    "Microsoft.AspNetCore.Mvc": "1.1.0",
    "Microsoft.AspNetCore.Routing": "1.1.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.1.0",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.0",
    "Microsoft.Extensions.Configuration.FileExtensions": "1.1.0",
    "Microsoft.Extensions.Configuration.Json": "1.1.0",
    "Microsoft.Extensions.Logging": "1.1.0",
    "Microsoft.Extensions.Logging.Console": "1.1.0",
    "Microsoft.Extensions.Logging.Debug": "1.1.0",
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.0"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.1.0-preview4-final"
  },

  "frameworks": {    
    "net462": {}
  },
...

• Create a new .NET Core library.
• In project.json, set ‘frameworks’ to just ‘net462’ and install EFCore 1.1 and Tools

{
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.EntityFrameworkCore.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final"    
  },
  "tools": {
    "Microsoft.EntityFrameworkCore.Tools.DotNet": "1.1.0-preview4-final"    
  },

  "frameworks": {
    "net462": {}
  }
}

• Add a reference in web api project to the library.
• In Package Manager, set the project to the library and try the Scaffold-Db command Scaffold-DbContext -Connection "server=<server>;Database=<dbname>;Integrated Security=true" Microsoft.EntityFrameworkCore.SqlServer -Verbose

The issue

Code is not generated and the error shown is:

Thank you @micdenny and @rowanmiller for all the workarounds. I’ve been able to scaffold the database using 1.0.0-preview3-final using the -StartupProject option.

Closing as we have a workaround… these issues are being resolved in future releases of the tools.
