System.Data.Linq

Kind: Service

Source: Pams/Data/Pams.Data/Pams.Data.csproj (line 1)

Part of: Pams

NuGet package dependency

System.Data.Linq is a NuGet package dependency declared for the Pams.Data project in Pams/Data/Pams.Data/Pams.Data.csproj. It supports the data layer's LINQ to SQL integration and is consumed by .NET code rather than directly by TypeScript or JavaScript.

Usage

ts
import { readFileSync } from "node:fs";
import { resolve } from "node:path";

const projectPath = resolve("Pams/Data/Pams.Data/Pams.Data.csproj");
const projectFile = readFileSync(projectPath, "utf8");

const hasSystemDataLinq =
  projectFile.includes('Include="System.Data.Linq"') ||
  projectFile.includes('PackageReference Include="System.Data.Linq"');

if (!hasSystemDataLinq) {
  throw new Error(
    "System.Data.Linq is not declared in the Pams.Data project file."
  );
}

console.log("System.Data.Linq dependency is declared.");

AI Coding Instructions

• Keep System.Data.Linq references inside the .NET data layer; TypeScript and JavaScript code should access data through an application API.
• Preserve the existing legacy project dependency format when editing Pams.Data.csproj.
• Check for both assembly references and PackageReference entries when validating this dependency.
• Avoid changing LINQ to SQL mappings or query behavior without checking the database schema and calling code.
