Updating Entity Framework Model

Question

I have just started using EF and found it cool, but I ran into a problem,

Problem:
I changed my DB schema of a column inside the table User, It

Answer 1

A lot of files in the EF model get f*****d. Removing and adding the entity was not enough. The entities was duplicated like table, table1, table_result, table1_result, table_result1, and so on... Model update was updating the duplicated references instead of the original.

I have to open notepad and fix manually these files:

EFModel.Context.cs
EFModel.edxm

And delete these files:

obj\Debug\edmxResourcesToEmbed\MYEfModel.csdl
obj\Debug\edmxResourcesToEmbed\MYEfModel.msl
obj\Debug\edmxResourcesToEmbed\MYEfModel.ssdl
