I am new to ASP.NET Core and using Entity Framework 6.
I have created a Web API using MySql. On development, I have executed add migrations and update-database command.
Now, I have published the Web API and I have to deploy it on a server. The server doesn't have development environment. I want to update the production database. How can I do this?`
I don't understand this : "The server doesn't have development environment."
You only have to replace Database ConnectionString of your project with ConnectionString of server, and then use update-database to update database.
I have a Web API project created in ASP.NET 5 which uses the dnx451 framework. The project uses Entity Framework 6.1.3 and MySql .NET connector (MySql.Data.Entity) version 6.9.7 to connect to a MySql database.
Since there is no web.config, I need to use code based configuration to connect to the database. But I have run up against problems here.
I have a DbConfiguration implementation to handle the configuration. I followed the example mentioned here: http://dan.cx/2015/08/entity-framework-6-mysql-aspnet
However, I get a compilation error at this line:
var dataSet = (DataSet)ConfigurationManager.GetSection("system.data");
The error is:
"Using the generic type 'ConfigurationManager' requires 1 type arguments".
Not sure what type argument I should pass in there.
I found it ! Just import "Microsoft.AspNet.Diagnostics.Entity": "7.0.0-rc1-final" in your project.json ;)

Trying to generate the entities with VS2013 using MYSQL connector/net 6.8.3.0 but it shows me the above error. Following are the screenshots of installed applications list and Nuget package manager.
Please help me to fix this.
MYSQL EF6 is having a new dll "MySql.Data.Entity.EF6.dll". Refer this dll in your assembly, rebuild the application and try again to generate the entities.

LocalDB is just another engine that is used to access a SQL server database file .mdf -- just like SQLExpress. Visual Studio 2012 uses LocalDB by default while Visual Studio 2010 uses SQLExpress. Anyhow, you can just replace the connection string used in the tutorial with your actual database connection string.
The following tutorial shows how to create a Web API project and connect to a data source using Entity Framework: msdn
It should give you the gist of what needs to be done.
