    NuGet-->>Converter: Provide package assembly
    Converter->>DataSet: Query DataTable or DataSet with LINQ extensions
    DataSet-->>Converter: Return typed query results

Usage

ts
// The NuGet package runs in the .NET currency converter service.
// JavaScript clients access the service through its API.

async function convertCurrency(
  amount: string,
  fromCurrency: string,
  toCurrency: string,
) {
  const response = await fetch("/api/currency/convert", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      amount,
      fromCurrency,
      toCurrency,
    }),
  });

  if (!response.ok) {
    throw new Error("Currency conversion request failed");
  }

  return response.json();
}

AI Coding Instructions

• Keep System.Data.DataSetExtensions as a server-side dependency; JavaScript clients cannot import or call the NuGet package directly.
• Use the package’s LINQ extension methods when querying DataSet or DataTable values in the .NET project.
• Check for missing tables, columns, and empty query results before reading values from a DataSet.
• Preserve the project’s existing legacy package declaration format when updating this dependency.
• Test currency conversion paths that depend on data returned from DataSet queries.
