Bring a large pot of water seasoned generously with salt to a boil. Cook the pasta until al dente according to the package directions. Drain the pasta and rinse thoroughly under cold water to halt cooking; drain once more and set aside.
In a spacious bowl, vigorously whisk together the olive oil, red wine vinegar, Dijon mustard, honey, 2 teaspoons kosher salt, and 3/4 teaspoon freshly ground black pepper.
Incorporate the cooked pasta, sliced cucumbers, halved cherry tomatoes, celery, radishes, corn kernels, shallot, parsley, and dill into the dressing. Toss thoroughly to ensure even distribution.
Let the salad rest at room temperature for a minimum of 30 minutes to allow flavors to meld, or refrigerate covered for up to 8 hours. Adjust seasoning with additional salt and pepper before serving. Serve at room temperatur
