OK, now to test the pipeline function, replace the ' sh ' in the above code with ' echo ', copy it into your jenkinsfile, and store it in the root directory of the Git repository.Create Pipeline Back to Jenkins Web page, add pipelineIf you want to automatically execute the p

name must start with "name=", otherwise Code-first will use it as the database name. Because the database name of the connection string in app. config is schooldb-byconnectionstring, Code-first creates a Schooldb-byconnectionstring A named database or use a database that already exists with the same name. Also, make sure that the connection string in app. config contains the providername = "System.Data.SqlClient" attribute.Summary: Code-first initializes the database by using different paramet
