C# filter file extensions

I created files as per

string[] names = {
    "Name001.product",
    "Name002.product",
    "Name003.product",
    "Name101.product.prototype",
    "Name102.product.prototype",
    "Name103.product.prototype",
};

foreach (var name in names)
{
    File.WriteAllText(name,"");
}

Then in another event

Directory.GetFiles(
    AppDomain.CurrentDomain.BaseDirectory,"*.product")
    .ToList()
    .ForEach(Console.WriteLine);

Console.WriteLine();

Directory.GetFiles(
    AppDomain.CurrentDomain.BaseDirectory, 
    "*.product.prototype")
    .ToList()
    .ForEach(Console.WriteLine);

Outputs

C:\Dotnetland\VS2019\ForumQuestion\Demo\bin\Debug\Name001.product
C:\Dotnetland\VS2019\ForumQuestion\Demo\bin\Debug\Name002.product
C:\Dotnetland\VS2019\ForumQuestion\Demo\bin\Debug\Name003.product

C:\Dotnetland\VS2019\ForumQuestion\Demo\bin\Debug\Name101.product.prototype
C:\Dotnetland\VS2019\ForumQuestion\Demo\bin\Debug\Name102.product.prototype
C:\Dotnetland\VS2019\ForumQuestion\Demo\bin\Debug\Name103.product.prototype

I ran the above code with .NET Core 5 and .NET Framework 4.8, both yield the same output.

Another example with a different pattern and predicate.

Directory.GetFiles(
        AppDomain.CurrentDomain.BaseDirectory, "Name*.*")
    .Where(fileName => !fileName.EndsWith("prototype"))
    .ToList()
    .ForEach(Console.WriteLine);
