Update-Database powershell scripts fails if Startup Project != Default project

Question

PM> Update-Database -Verbose
Using NuGet project 'RSP2.Competitions'.
Using StartUp project 'RSP2.Competitions.Timer'.
System.IO.FileNotFoundException: Could not load file or assembly 'RSP2.Competitions' or one of its dependencies. The system cannot find the file specified.
File name: 'RSP2.Competitions'
   at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks)

   at System.Data.Entity.Migrations.Design.ToolingFacade.UpdateRunner.RunCore()
   at System.Data.Entity.Migrations.Design.ToolingFacade.BaseRunner.Run()

Everything works fine if Startup Project == Default project

Bug has been found in VS 2010 SP1 on EF 4.3 beta 1

This 'bug' is also in the final release. Annoying. You need to add -StartUpProjectName "Your Project Name" to the add-migration/update-database commands
