ASP.NET Core EF Add-Migration command not working
asp.net-core c# entity-framework-core visual-studio-2015
Question
Following this Microsoft Tutorial when I run the PM> Add-Migration MyFirstMigration command in VS2015 project created from the same tutorial I get the following error that I can't resolve:
More than one DbContext was found. Specify which one to use. Use the '-Context' parameter for PowerShell commands and the '--context' parameter for dotnet commands.
Point to note
- I'm using the above tutorial with the exception that I'm using
Individual User Accountauthentication instead ofNo Authenticationused in the tutorial. - I've latest release of
ASP.NeT Core 1.0 and VS2015-Update 3 on windows 8.1 - This is a freshly created project. No other DbContext was manually installed
Accepted Answer
Running the following command (obtained from this article) and a response from @Maverik (from STackoverflow here) and a suggestion from @doctor above helped me resolved the issue. Thank you all for your help:
PM> Add-Migration MyFirstMigration -Context BloggingContext
Popular Answer
The error clearly explains to mention --context with db Context name if more than one DbContext. So try by mentioning your DbContext name.
dotnet ef migrations add Initial --context SampleDbContext
Hope this helps.
