I'm learning to create a web application in asp.net and following this documentation :
https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/creating-an-entity-framework-data-model-for-an-asp-net-mvc-application

after completing all the step i'm getting this error and i don't know what to do with it

Error:

System.InvalidOperationException: 'Failed to set database initializer of 
type 'Clothing_Store.DAL.CustomerInit, Clothing_Store' for DbContext type ' 
Clothing_Store.DAL.ShopContext, Clothing_Store' specified in the

In your web.config, there is an extra space added in the <context type="

<context type=" Clothing_Store.DAL.ShopContext, Clothing_Store">
 ^

Can you please remove that and re-run the application.

Have you tried to "rebuild" the application instead of using "build"? You can also try to "clean" the project first and then "build". Does the project "Clothing_Store" have the EntityFramework dlls? Also check if the Clothing_Store.dll is created in the bin folder of the Asp.net MVC application.
