Cannot Drop Database

Question

This is the error and the additional info:
An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll
Additional information: Cannot drop the database 'master' because it is a system database.
I am using the code first MVC data context method,
originally I created a database using the:
public class CustomDatabaseInitializer : CreateDatabaseIfNotExists<DataContext>
it worked and created a data base fine called Master.
Then I added SimpleMembership and used this method:
public
classCustomDatabaseInitializer:
DropCreateDatabaseIfModelChanges<DataContext>
but it gives the preceding error, does anyone know about this?

Problem Resolved. Thank You,
This was the ConnectionString and I created the master because that was the Calalog="Master" I changed to Catolog="CodedInventoryDEV"
<addname="CodedInventoryDEV"connectionString="Data
Source=(localdb)\ProjectsV12;Initial Catalog=CodedInventoryDEV;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False"providerName="System.Data.SqlClient"/>

Hello,
>>it worked and created a data base fine called Master.
I am a bit confused how you create the master database, because this database is a
system database which exists as soon as the database instance is created and we cannot drop it. As far as I know, for the database name in code first approach, it follows the
rule: its namespace + class name.
By default, it uses its namespace + class name as the database name, please check if you use the mode.
I am not sure if you have specify the database to the “master” by using ways described in this
blog(Point 7), if you have, I do not suggest that you use that key word in database, please use other name instead.
