解决 "No MigrationSqlGenerator found for provider 'System.Data.SQLite'" 错误

The error message 'No MigrationSqlGenerator found for provider 'System.Data.SQLite'. Use the SetSqlGenerator method in the target migrations configuration class to register additional SQL generators.' indicates that there is no MigrationSqlGenerator available for the SQLite provider. To resolve this issue, you need to register a custom SQL generator for SQLite in your migrations configuration class. Here's how you can do it: 1. Create a new class that inherits from DbMigrationsConfiguration<TContext> where TContext is your DbContext class. csharp
public class YourMigrationsConfiguration : DbMigrationsConfiguration<YourDbContext>
{
 public YourMigrationsConfiguration()
 {
 // Set the appropriate target database provider
 SetSqlGenerator('System.Data.SQLite', new SQLiteMigrationSqlGenerator());
 }
}
 2. In the constructor of your migrations configuration class, call the SetSqlGenerator method, passing the provider name ('System.Data.SQLite') and an instance of your custom SQLiteMigrationSqlGenerator class. 3. Implement the SQLiteMigrationSqlGenerator class by inheriting from the base MigrationSqlGenerator class and override the necessary methods to generate the required SQL statements for SQLite. csharp
public class SQLiteMigrationSqlGenerator : MigrationSqlGenerator
{
 // Override the necessary methods to generate SQL statements for SQLite
}
 By following these steps, you will register a custom MigrationSqlGenerator for the SQLite provider, and the error message should no longer appear.'}
