我试图解耦一些具体的类和链接使用SimpleIOC从MVVMLight。这是我的类，我想做一个接口，然后我可以注册simpleioc

public class SerialisationService : ISerialisationService
{
    private static async Task<T> LoadLocalXMLAsync<T>(string filename)
    {
        try
        {
            StorageFile file = await ApplicationData.Current.LocalFolder.GetFileAsync(filename);
            T o = default(T);
            using (IInputStream inStream = await file.OpenSequentialReadAsync())
            {
                var serializer = new DataContractSerializer(typeof(T));
                o = (T)serializer.ReadObject(inStream.AsStreamForRead());
            }
            return o;
        }
        catch (Exception ex)
        {
            return default(T);
            // ERROR HANDLING AND LOGGING
        }
    }
    private async static Task SaveLocalXMLAsync(string filename, object o)
    {
        try
        {
            var serializer = new DataContractSerializer(o.GetType());
            StorageFile file = await ApplicationData.Current.LocalFolder.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting);
            using (Stream fileStream = await file.OpenStreamForWriteAsync())
            {
                serializer.WriteObject(fileStream, o);
                await fileStream.FlushAsync();
            }
        }
        catch (Exception ex)
        {
            // ERROR HANDLING AND LOGGING
        }
    }
}

我已经尝试了一些东西，不能工作出我如何定义一个通用接口返回任务在这种情况下。

我需要使用

注册
SimpleIoc.Default.Register<ISerialisationService, SerialisationService>();

The Interface:

public interface ISerialisationService
{
    Task<T> LoadLocalXMLAsync<T>(string filename);
    Task SaveLocalXMLAsync(string filename, object o);
}
实现:

public class SerialisationService : ISerialisationService
{
    public async Task<T> LoadLocalXMLAsync<T>(string filename)
    {
        try
        {
            StorageFile file = await ApplicationData.Current.LocalFolder.GetFileAsync(filename);
            T o = default(T);
            using (IInputStream inStream = await file.OpenSequentialReadAsync())
            {
                var serializer = new DataContractSerializer(typeof(T));
                o = (T)serializer.ReadObject(inStream.AsStreamForRead());
            }
            return o;
        }
        catch (Exception ex)
        {
            return default(T);
            // ERROR HANDLING AND LOGGING
        }
    }
    public async Task SaveLocalXMLAsync(string filename, object o)
    {
        try
        {
            var serializer = new DataContractSerializer(o.GetType());
            StorageFile file = await ApplicationData.Current.LocalFolder.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting);
            using (Stream fileStream = await file.OpenStreamForWriteAsync())
            {
                serializer.WriteObject(fileStream, o);
                await fileStream.FlushAsync();
            }
        }
        catch (Exception ex)
        {
            // ERROR HANDLING AND LOGGING
        }
    }
}
