method not suitable for an entry point

I get the error Program does not contain a static Main method suitable for an entry point. I want to use the method UploadFileToBlobStorage in the main method.

Here is my main method:

 public static void Main(string[] args,BlobContainerClient containerClient)
{
    _ = CreateBlobClientContainerAsync();

    _ = UploadFileToBlobStorage(containerClient);

    Console.WriteLine("Press any key to exit.");
    Console.ReadLine();
}

and here is the UploadFileToBlobStorage method:

public static async Task<int> UploadFileToBlobStorage(BlobContainerClient containerClient)
{
    // Create a local file in the ./data/ directory for uploading and downloading
    string localPath = "./data/";
    string fileName = "perfblob" + Guid.NewGuid().ToString() + ".txt";
    string localFilePath = Path.Combine(localPath, fileName);

    // Write text to the file
    await File.WriteAllTextAsync(localFilePath, "Blob Upload!");

    // Get a reference to a blob
    BlobClient blobClient = containerClient.GetBlobClient(fileName);

    Console.WriteLine("Uploading to Blob storage as blob:\n\t {0}\n", blobClient.Uri);

    // Upload data from the local file
    await blobClient.UploadAsync(localFilePath, true);

    return 200;
}
