Manipulating data with Entity Framework using Knockout and AngularJS

When creating a knockout restful service, the first attempt was successful. However, upon implementing it in Angular, there were issues with the database displaying an ID with other fields labeled as undefined. Trying to fix this, I recreated the WCF Service and ensured that the information matched the SQL DB connected to the Visual Studio Project. Despite these efforts, an error persists which prevents data storage. Clicking on the exception help link led to advice for a different issue. Unfortunately, I am unable to post a picture due to limited reputation on this site.

The Exception:

TypeInitializationException was unhandled by user code    
An exception of type 'System.TypeIntifializationException' occurred in 
EntityFramework.dll but was not handled in user code

Additional information: 
The type initializer for 'System.Data.Entity.AppConfig' threw an exception.

Both necessary references have been added to the project through packages. Any guidance would be appreciated, as I have already recreated this project multiple times.

Answer №1

One common issue is that the app.config file being utilized by your solution, usually the one designated as the startup project, may not include Entity Framework's initialization details or the connection string for the EF context. To resolve this, consider installing EF in that specific project or transferring the necessary lines from a different configuration file.
