我有一個Silverlight應用程序，它在我的asp.net應用程序中使用WCF服務。Silverlight應用程序以墨跡筆畫的形式保存「繪畫」。這些筆畫的形式是xaml（可能很大），我將其轉換爲字符串併發送到服務以將字符串保存到sql server。 （基本上做這個應用程序相同的類型http://msdn.microsoft.com/en-us/magazine/cc721604.aspx）。遠程服務器返回錯誤：NotFound
這個工作，我可以看到我的服務方法正在打的時候，繪圖是相對較小，但如果繪圖變得很大，我得到這個偉大的錯誤和服務方法斷點永遠不會被擊中。看起來我已經通過了一個規模門檻，但我無法弄清楚我是對的還是要改變什麼才能解決問題。
我已經谷歌和SO沒有成功，所以任何幫助將不勝感激。提前致謝。
我的服務：
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class DrawingService: IDrawingService
{
#region IDrawingService Members
public bool SaveEvalAreaDrawing(int EvalAreaId, string xmlToSave)
{
return true;
}
public bool SaveEvalItemDrawing(int EvalItemId, string xmlToSave)
{
return true;
}
public string GetEvalAreaDrawing(int EvalAreaId, string xmlToSave)
{
return "you got the eval drawing!";
}
public string GetEvalItemDrawing(int EvalItemId, string xmlToSave)
{
return "you got the eval item drawing!";
}
#endregion
}
我與服務的web.config asp.net應用

當VS顯示錯誤

object[] _args = new object[0];
bool _result = ((bool)(base.EndInvoke("SaveEvalAreaDrawing", _args, result))); // Here is where is popping up

}

哪裏是_actual_錯誤的內容，其所有的宏偉？ – 2011-03-03 19:43:01
@Mr。失望 - 對不起，沒有發佈，因爲我讀過它的一個非常普遍和無益的錯誤，但我會編輯我的文章。 – AGoodDisplayName 2011-03-03 19:56:24
