Question

我正在尝试编写一个简单的Silverlight应用程序，它上面有几个按钮，但我一直收到这个错误。我已经离开文件资源管理器以查看有关更改文件权限的信息，以便MS Studio可以找到它，但到目前为止还没有发现任何变化。

问题：在Visual Studio for Silverlight中是否需要更改某些内容才能正常工作？

Silverlight 4是我对WEBApplication的目标。

我不确定需要在这个问题上添加什么才能让每个人都知道我在问什么。我认为它只是一个来自MS的文件，必须启用，这是SilverlightApplication3.dll，但我没有真正的运气启用它。

错误：

Error   1   Could not load the assembly file:///C:\Users\itpr13266\Desktop\C++\SilverlightApplication3\SilverlightApplication3\obj\Debug\SilverlightApplication3.dll. This assembly may have been downloaded from the Web.  If an assembly has been downloaded from the Web, it is flagged by Windows as being a Web file, even if it resides on the local computer.

                System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight Application " + errorMsg + "\");");
            }
            catch (Exception)
            {
            }
        }

Silverlight给我一个错误，说明.dll文件没有启用？
