部署 Entity Framework WPF 应用程序
Deploying Entity Framework WPF Application
我制作了一个使用 EF6 代码优先数据库的 WPF 应用程序。
我一直在 Visual Studio 中完成这一切并使用默认的 LocalDb。
客户想测试我到目前为止所做的事情。我已经尝试将 ClickOnce 应用程序安装到我的开发 PC 上。该程序根本无法启动，没有 window 打开....绝对没有任何反应。
我已经部署了一个简单的 WPF 应用程序，它可以立即运行，所以我推测它是 EF 组件。
- 我如何获得某种输出日志或调试以便我可以看到错误是什么？
- 关于如何修复错误的任何想法？
- 它安装到哪里？
- 如何附加调试器？

更新 4 - 使用 DbConfig
今天早些时候，我 运行 手动安装了 SQLExpress，并使用了所有选项的默认值。
我已经根据我在 msdn 更新中找到的内容转换为 DbConfig。这在 visual studio 中再次起作用。以我给 DbContext 构造函数的名称创建 Db。
只是为了确保我卸载了 ClickOnce 安装的程序。重新安装。当我早些时候摆弄时我注意到了这一点，但我现在看到一个对话框说 "Cannot Start Application || Application cannot be started. Contact the application Vendor"。与之前应用程序 运行 然后崩溃的情况不同。这种新方法没有给我自定义异常日志，但我确实得到了如下所示的详细信息：

解决方案/ / 总结
感谢 grek40。特别是他的异常捕获代码。这使我可以开始进行更改以查找错误。在此之前，windows 日志根本没有帮助。
让我越过障碍的是使用他建议的 DbContext 定义。出于某种原因，使用默认的 DbContext 构造函数和连接字符串似乎使 ClickOnce 安装期望找到 mdf 文件；即使没有指定附加一个。
异常捕获代码还允许我在发布模式下进行调试以找到一些奇怪的异常（曾经不适用于调试模式，或者对我来说没有任何意义）。我现在关闭了有问题的代码，这样我就可以继续了；单击一次安装现在可以使用了。
我想确保您确实尽一切可能捕获并记录发生的异常。
确保在 App.xaml 中使用 DispatcherUnhandledException
注册异常处理程序
<Application
x:Class="[Your Stuff]"
DispatcherUnhandledException="Application_DispatcherUnhandledException">
</Application>
在处理程序中实现一些日志记录（在 App.xaml.cs 内）。它应该是总结所有内部异常的异常消息及其堆栈跟踪的东西。只需将该信息写入某种日志文件（在我的示例中为 C:\Temp\MyAppCrashes.log）。
private void Application_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
var sb = new StringBuilder();
AppendExceptionMessages(sb, e.Exception);
AppendExceptionStacktraces(sb, e.Exception);
File.AppendAllText(@"C:\Temp\MyAppCrashes.log", sb.ToString());
}
private void AppendExceptionMessages(StringBuilder sb, Exception e)
{
while (e != null)
{
sb.AppendLine("============== Exception ===============").AppendLine(e.Message);
e = e.InnerException;
}
}
private void AppendExceptionStacktraces(StringBuilder sb, Exception e)
{
while (e != null)
{
sb.AppendLine("======== Exception Stacktrace ==========").AppendLine(e.StackTrace);
e = e.InnerException;
}
}
我希望这能揭示更多信息，如果这还不够，请确保在 App.xaml 中注册一个 Startup 处理程序而不是 StartupUri。在启动时，在创建任何 window 之前，创建一个数据库上下文实例，调用 db.Database.Exists() 和 db.Database.Initialize(true)，确保检查 Exists return 值并将调用包装在 try-catch 中。当然，如果捕获到任何异常，请写日志详细信息。
到目前为止，希望您能找到任何与该方法相关的东西。
我制作了一个使用 EF6 代码优先数据库的 WPF 应用程序。 我一直在 Visual Studio 中完成这一切并使用默认的 LocalDb。 客户想测试我到目前为止所做的事情。我已经尝试将 ClickOnce 应用程序安装到我的开发 PC 上。该程序根本无法启动，没有 window 打开....绝对没有任何反应。 我已经部署了一个简单的 WPF 应用程序，它可以立即运行，所以我推测它是 EF 组件。

更新 4 - 使用 DbConfig 今天早些时候，我 运行 手动安装了 SQLExpress，并使用了所有选项的默认值。 我已经根据我在 msdn 更新中找到的内容转换为 DbConfig。这在 visual studio 中再次起作用。以我给 DbContext 构造函数的名称创建 Db。 只是为了确保我卸载了 ClickOnce 安装的程序。重新安装。当我早些时候摆弄时我注意到了这一点，但我现在看到一个对话框说 "Cannot Start Application || Application cannot be started. Contact the application Vendor"。与之前应用程序 运行 然后崩溃的情况不同。这种新方法没有给我自定义异常日志，但我确实得到了如下所示的详细信息：

解决方案/ / 总结 感谢 grek40。特别是他的异常捕获代码。这使我可以开始进行更改以查找错误。在此之前，windows 日志根本没有帮助。 让我越过障碍的是使用他建议的 DbContext 定义。出于某种原因，使用默认的 DbContext 构造函数和连接字符串似乎使 ClickOnce 安装期望找到 mdf 文件；即使没有指定附加一个。 异常捕获代码还允许我在发布模式下进行调试以找到一些奇怪的异常（曾经不适用于调试模式，或者对我来说没有任何意义）。我现在关闭了有问题的代码，这样我就可以继续了；单击一次安装现在可以使用了。
我想确保您确实尽一切可能捕获并记录发生的异常。
确保在 App.xaml 中使用 DispatcherUnhandledException
<Application
x:Class="[Your Stuff]"
DispatcherUnhandledException="Application_DispatcherUnhandledException">
</Application>
在处理程序中实现一些日志记录（在 App.xaml.cs 内）。它应该是总结所有内部异常的异常消息及其堆栈跟踪的东西。只需将该信息写入某种日志文件（在我的示例中为 C:\Temp\MyAppCrashes.log）。
private void Application_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
var sb = new StringBuilder();
AppendExceptionMessages(sb, e.Exception);
AppendExceptionStacktraces(sb, e.Exception);
File.AppendAllText(@"C:\Temp\MyAppCrashes.log", sb.ToString());
}
private void AppendExceptionMessages(StringBuilder sb, Exception e)
{
while (e != null)
{
sb.AppendLine("============== Exception ===============").AppendLine(e.Message);
e = e.InnerException;
}
}
private void AppendExceptionStacktraces(StringBuilder sb, Exception e)
{
while (e != null)
{
sb.AppendLine("======== Exception Stacktrace ==========").AppendLine(e.StackTrace);
e = e.InnerException;
}
}
我希望这能揭示更多信息，如果这还不够，请确保在 App.xaml 中注册一个 Startup 处理程序而不是 StartupUri。在启动时，在创建任何 window 之前，创建一个数据库上下文实例，调用 db.Database.Exists() 和 db.Database.Initialize(true)，确保检查 Exists return 值并将调用包装在 try-catch 中。当然，如果捕获到任何异常，请写日志详细信息。
到目前为止，希望您能找到任何与该方法相关的东西。
