Asp conenction error when the database is updating
This would mirror the same kind of configuration and initialization that happens in ASP. The important thing here is that this allows me to AVOID marking as Copy Always in the Benday. The two private methods understand 1) how to create instances of Configuration Builder() with the correct references to and environment variables and 2) how to grab a connection string and create an instance of your Db Context class. It turns out that when you run your dotnet ef commands against this project from the command line, it sets the working directory to be the ./bin/debug/netappcore1.* directory and attempts to find the in that directory. I recompiled and re-ran my dotnet ef database migration update commands and it worked.aspdotnet-suresh offers C#articles and tutorials,csharp dot net,articles and tutorials, VB.
In the current configuration, the default action is that, when you run the application fro the first time and register as a user, the database will be created as a SQL Server CE (.sfd) or SQL Express (.mdf) file in the .In this case, we will swap out the SQL CE connection for a SQL Server development database I have running on my development machine (obviously, you can point this at any database you wish, or simply leave it set to use the local SQL CE database): Now, if I run the application, I am greeted with the default home screen offered by the VS 2013 MVC project template: From here, I click on the “register” link upper right: When I complete registration and hit the “Register” button, I am redirected back to the home page. However, nothing we have done to this point has created or modified an actual database. With all that done, run the following command from the console: we find that we now have four test users: Now that we have a basic migration strategy in place, let’s take a look at extending the elementary Application User class to incorporate some additional data fields. NET new Identity Model, it is easier than before to extend the basic user representation to include arbitrary fields suitable for our application management.However, we can see now, in the upper right corner, that I am, in fact, signed in as a registered user: None of this is surprising. For example, Let’s assume we would like our user information to include an email address, as well as full first and last names.However, you can see that a full range of identity management tables have been created, including those for role management, and external authorization (using Google/Facebook/Twitter accounts). We need to add values for the new table schema, but our seed data will not be updated, because Entity Framework doesn’t like to do things which will cause data loss.As we develop, we may make changes to our classes which need to be reflected in the database. While there are ways to make this happen, they are beyond the scope of this article.
