How do know it didn't create the database? If everything works fine, I mean no errors, the database should be created already.
My guess is you didn't specify the connection string which caused the database created in SQL Express.

first time when i execute the code then code do not show any error and execute fine and show the signup view when i finish the execution and check it does not make database. if i run again and provide the values in signup form then it create database. why this is odd behviour? it should create database when i execute and browse the page Commented Jun 13, 2013 at 9:13

It will create database when you first access the database. I'm sure the signup httpget action doesn't access the database.– Jason LiCommented Jun 13, 2013 at 9:14
I guess you are using the wrong database creation strategy

What kind of Wrong Strategy??? i have two basic classes of userLogin ,and User sign up class and anther class is UserContext class that is inherit from DbContext class and to create a databse table i use 'public DbSet<Category> Categories { get; set; } public DbSet<Product> Products { get; set; }' method for constr 'public OnlineShopContext() :base("Name=Constr3") { }' Commented Jun 13, 2013 at 8:53

And constr is ' <connectionStrings> <clear /> <add name="Constr3" connectionString="Data Source=.;Initial Catalog=EShop1;Integrated Security=true" providerName="System.Data.SqlClient" /> </connectionStrings> ' Commented Jun 13, 2013 at 8:56
