.NET - Creating an async-capable background task

In the old days we used BackgroundWorkers, but these days we want to create tasks we can run with the async keyword. Here is an example for a task that will return a boolean:

public async Task Test()
{
    bool result = false;
    Exception error = null;

    await Task.Run(() =>
    {
        try
        {
            result = someSlowComponent.getBooleanResult();
        }
        catch (Exception ex)
        {
            error = ex;
        }
    });

    if (error != null)
        throw error;
    else
        return result;
}

You can now await this method and make it asynchronous:

public async bool GetValue()
{
    bool result = await Test();

    //Do more things with the result.

    return result;
}
