EF 6 Code based migration exception: Microsoft.VisualStudio.Data.Tools.Package not serializable?

Question

I have this configuration

internal sealed class Configuration :DbMigrationsConfiguration<IAS.Models.ApplicationDbContext> {
            public Configuration() {
                AutomaticMigrationsEnabled = false;
                ContextKey = "IAS.Models.ApplicationDbContext";
            }

            protected override void Seed( IAS.Models.ApplicationDbContext context ) {
                var baseDir = AppDomain.CurrentDomain.BaseDirectory;
                context.Database.ExecuteSqlCommand(File.ReadAllText(baseDir + "\\MyInsertScriptsql"));
        }
    }

when running upate-dataabase i get the following exception

Excepción al llamar a "SetData" con los argumentos "2": "El tipo 'Microsoft.VisualStudio.Data.Tools.Package.Internal.OAProject' del ensamblado 'Microsoft.VisualStudio.Data.Tools.Pa ckage, Version=11.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' no está marcado como serializable."

Answer 1

Problem solved, i opened the file ..\packages\EntityFramework.6.0.0\tools\EntityFramework.psm and the line 611 states:

 $domain.SetData('startUpProject', $startUpProject)

I them after review my solution I found that the startup project was changed to the Database project, corrected this and the problem was gone.
