部署数据库优先 C# ASP.NET MVC 应用程序 - 连接到不同的数据库

Question

I'm trying to deploy a database-first application I have created. I'm using an .edmx file for the models. I've been using a local db for testing and building but now I'm to the point where I need to demo and get feedback. In order to deploy it, I changed the connection string to:

<add name="Entities" 
     connectionString="metadata=res://*/Models.DBModels.csdl|res://*/Models.DBModels.ssdl|res://*/Models.DBModels.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=servername;Initial Catalog=CRMS;Integrated Security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" 
     providerName="System.Data.EntityClient" />

So that it would connect to the new database. However, this doesn't work and I get a metadata path is not valid error.

This is my first database-first app. I supposed I could create another .edmx file based off the production database but there has to be an easier way.

I met with a similar error but I ended up creating another.edmx file because sometimes there will be issues with EF internally when you try to move/change and rerun it.
