EF5 Migration Update-Database -Script Error

Question

I've been using Visual Studio 2012 RC with trial license with no problems. I purchased Visual Studio 2012 Professional yesterday, installed the latest version, and installed Update 1.

I have a solution/project I've been working on for many years. It has many migrations in it. I ran my first add-migration TableX_NewField and update-database -sourcemigration:TableX_PreviousNewField in this latest version.

They both ran with no problems.

Then I ran update-database -script -sourcemigration:TableX_PreviousNewField and received the following:

PM> update-database -script -sourcemigration:TableX_PreviousNewField
Applying code-based migrations: [201301151003149_TableX_NewField].

I've ran windows updates. Checked updates with NuGet. Restarted my computer. Still have error.

Answer 1

I noticed in visual studio, going to SQL menu, Transact-SQL Editor, New Query... gave a dialog about the tools not working with the server installed. Installing SQL Server Data Tools - December 2012 update ( Sql Server Data Tools ) fixed the problem

Answer 2

This issue is resolved. I uninstalled and then installed and the problem was not resolved. I then did two things at the same time; so I do not know which resolved the issue:

1. Deleted all folders and files in %temp%.
2. Ran devenv /resetsettings.

Hope this helps anyone who runs into a similar issue.
