How to fix connection error?

Question

SQL Server

I can't log in to the web application (downloaded from github)

Cannot open database "aspnet-Catalogue-20180108113947" requested by the login. The login failed. Login failed for user ' '?

. written in c#

Answer 1

Set connection rights for the specified user.
Or go to "SQL Authentication" and configure the login there.

Answer 2

In web.config look for this line.
From the studio or sql management studio create a database "aspnet-Catalogue-20180108113947"
The most optimal method is to bring the connection string to the form

Server=localhost;Database=aspnet-Catalogue-20180108113947;Trusted_Connection=True;

Or mind if you have SQLExpress

Server=localhost\SQLExpress;Database=aspnet-Catalogue-20180108113947;Trusted_Connection=True;

Then, if necessary, in the studio console, execute the command

ef update database
