<\/span><\/h2>\nFinally, you’re done! To perform operations such as inserting, updating, and deleting data from the database, create an instance of the model context, and call the corresponding methods on the entities.<\/p>\n
The following code is an example:<\/p>\n
\nusing(var context = new MyModelContext())\n{\n \/\/ Insert a new record\n var entity = new MyEntity { Name = \"John Doe\", Age = 35 };\n context.MyEntities.Add(entity);\n context.SaveChanges();\n \n \/\/ Update an existing record\n var entityToUpdate = context.MyEntities.FirstOrDefault(e => e.Id == 1);\n entityToUpdate.Name = \"Jane Doe\";\n context.SaveChanges();\n \n \/\/ Delete a record\n var entityToDelete = context.MyEntities.FirstOrDefault(e => e.Id == 2);\n context.MyEntities.Remove(entityToDelete);\n context.SaveChanges();\n}\n<\/code><\/pre>\n<\/span>Conclusion<\/span><\/h2>\nHurray!
