The server method can return a Task, if it's doing work that can be executed asynchronously. For example, talking to a database, calling another API, or accessing the file system.

Whether or not the server method returns a Task, the calling client can use a Task to call the server. The network request will be the asynchronous part of the call; the client doesn't care how the server handles the request.

Eg:

Server:
public int Foo()
{
    return 42;
}

public async Task<int> BarAsync()
{
    using (var connection = new SqlConnection("..."))
    using (var command = new SqlCommand("...", connection))
    {
        await connection.OpenAsync();
        object result = await command.ExecuteScalarAsync();
        return Convert.ToInt32(result);
    }
}
Client:
private readonly HttpClient _client;

public async Task<int> FooAsync()
{
    using (var response = await _client.GetAsync("/api/foo"))
    {
        response.EnsureSuccessStatusCode();
        return await response.ReadAsAsync<int>();
    }
}

public async Task<int> BarAsync()
{
    using (var response = await _client.GetAsync("/api/bar"))
    {
        response.EnsureSuccessStatusCode();
        return await response.ReadAsAsync<int>();
    }
}
