为Package Manager迁移操作指定“项目名称”

Question

I recently restored my Visual Studio solution by cloning from a remote GIT repository. Now, for some mysterious reason, "migration" commands that I enter in the Package Manager Console (eg "get-migrations") fail unless I explicitly specify the main project name, eg:

get-migrations -projectname Indigo

If I omit the project name then it looks in a project that isn't the main project, and it complains:

PM> get-migrations
Retrieving migrations that have been applied to the target database.
No migrations configuration type was found in the assembly 'Indigo.Tests'.
  (In Visual Studio you can use the Enable-Migrations command from Package
  Manager Console to add a migrations configuration).

Where is VS getting its concept of the project tied to the database? How do I teach VS to use the correct project by default?

Answer 1

When you open the Package Manager Console , the default project will automatically be assigned to the name of the startup project in your solution even if this project doesn't contain a EF Context.

If you can't set the project that contain your EF context as a startup project for your solution then the only choice you have is to manually set the Default project dropdown list to the correct project name. By doing that you will not need to specify the name of the project when typing your commands.
