DefaultConnectionStringProvider Class

Enables you to resolve connection strings by their names at runtime in .NET Core applications.

Namespace:DevExpress.DataAccess
Assembly:DevExpress.Data.v19.2.dll

Expanded Syntax

Expanded Remarks

In ASP.NET Core applications, the default connection string provider implementation uses the IConfiguration service to read connection strings. Applications created based on ASP.NET Core templates call the CreateDefaultBuilder method in the Program.cs file to register this service. If the IConfiguration service is not registered, the default provider searches the appsettings.json file in the current directory and reads connection strings from the file’s ConnectionStrings section.

You can override the default connection string provider to get connection strings from a set of different configuration sources, such as appsettings.Development.json, connectionStrings.json, in-memory collection, etc.

  1. Create a custom configuration and load connection strings from all the required sources. For instance, create the ConfigurationBuilder class instance and use its extension methods (AddJson, AddInMemoryCollection, etc.) See Configuration in ASP.NET Core for more information.

  2. Call the static AssignConnectionStrings method at application startup after the UseDevExpressControls method call to register connection strings globally.
