The UseSqlServer method configures the context to use a SQL Server database, and takes a string representing the connection string as a parameter: protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) Most providers include convenience methods that extend the DbContextOptionsBuilder type, so that configuration can be simplified. The OnConfiguring method is called every time that an an instance of the context is created. The DbContext type has a virtual OnConfiguring method which is designed to be overridden so that you can provide configuration information for the context via the method's DbContextOptionsBuilder parameter. There are a number of ways to achieve this. Once you have constructed your connection string, you meed to make it available to your DbContext. database=Test trusted_user=true Ĭonnection strings for most providers, are documented here. The following example shows a connection string for a SQL Server database named Test, attached to the default, unnamed instance of SQL Server: server=. The information is provided as key/value pairs, separated by semi-colons. This information varies from provider to provider, but will usually include the name and location of the source, and optionally some means of authenticating the user. Database First And Entity Framework CoreĬonnection strings contain information about the data source that is being connected to.Many To Many Relationship Configuration.Neither of these are a simple answer suitable for this forum, but there is plenty of documentation depending on which way you choose to go.
Instead, consider either using a hosting service (some do allow remote access to DB's, but these are generally ones you have to pay annually for) or a cloud solution (which again, you will have to pay for).Ĭopy Code < /configurationIf your server is not visible to the internet, you have two options either you configure the instance of SQL Server to be visible on the internet or you would need to set up a VPN. But getting to that point requires a lot of thinking and planning, or it'll all fall over very, very quickly. Once that lot is sorted, it's simply a case of using the domain or IP address as part of your connection string, and it'll all work like magic.
Then there is the security concerns, which are a whole new bag of rats! Then there is the router, which probably has to be configured to support the incoming requests by unblocking ports, the OS and it's firewall which also has to allow them, and the SQL Server installation which has to be configured to allow remote access. You can get Static IP addresses, but they generally cost extra and have to be agreed in advance.
Because it changes, you can't use an IP address directly to connect, and you can't support a domain name on that PC because the DNS expects a Static IP and won't direct traffic correctly with Dynamic. That's because "normal connections" are via Dynamic IP addresses which means each time the router is cycled a new IP address is assigned by the ISP. If it's a standard domestic line, forget it. That's not necessarily as simple as it sounds: it's going to depend a lot on how the remote server is connected to the internet.
