Code Generation Utility

The Code Generation tool is an external tool used for generating required classes and ORM mappings that are necessary to build the solution. Code generation is required when working on the solution to create the core objects, profiles, and extensions. This article describes how code generation is built into the initdev command for local development and how it can be executed from a CI/CD pipeline.

Running initdev​

The code generation utility is integrated into the initdev process. When you run Initialize-PowershellForDevelopment.ps1 followed by initdev (as outlined in the Getting Started Guide), the codegen utility is downloaded from Azure Artifacts into the tools folder under the Ed-Fi-ODS-Implementation repository and is executed after the Invoke-NewDevelopmentAppSettings task.

Manual Execution​

The code generation utility can be run from the command line.

Installation​

To Install the code generation tool manually, run Initialize-PowershellForDevelopment.ps1 script from a PowerShell prompt as outlined in the Getting Started Guide, followed by the Install-CodeGenUtiltity command. This will pull the current version of the tool, and install it into the tools folder under the Ed-Fi-ODS-Implementation repository.

PS D:\ed-fi\Ed-Fi-ODS-Implementation> Install-CodeGenUtility

Execution​

To run code generation independently from the build process, the tool can be executed by calling the PowerShell command Run-CodeGen. This will execute the generation process for all required classes.
