嵌套的dart项目阻止ServiceStack.Razor视图呈现

标签： c# dart servicestack servicestack-razor

情况

我正在使用许可的ServiceStack 4.0.12开发纯ServiceStack / Razor应用程序（没有MVC4或Web API）。我有一个视图（cshtml）引用一个从dart项目（使用AngularDart）转换的Javascript文件。

为方便起见，我将dart项目文件夹嵌套在ServiceStack项目中，但不将其包含在Visual Studio中。然后我分别使用Dart编辑器处理我的dart项目。

整个项目结构如下所示：

MyApp.csproj
Global.asax.cs
\Controllers           <- contains the IService formatted by 'Views\index.cshtml'.
\Dart                  <- not included in Visual Studio project.
     \packages
     \build
           \myapp.dart.js
     \lib
     \web
         \myapp.dart
\Views                 
      \index.cshtml    <- references 'myapp.dart.js'

我在本地IIS中设置了一个简单的，工作正常的ServiceStack / Razor'Hello World'，然后切换到Dart编辑器来设置我的dart项目。

问题

想象一下，几分钟后我的挫败感转回来，却发现我的美丽“Hello World”已经被“指数快照”所取代。没有触及一行代码，配置或重新编译。

当我切换到IIS Express时，ServiceStack / Razor应用程序将再次正常工作。相同的代码，不需要更改配置或重新编译。

在丢失头发几个小时后，调试各种配置设置并使用沙盒项目无效，我碰巧移动VS项目文件夹中的'Dart'文件夹，修改了Web.config并刷新了应用程序 - 和该应用再次运作！

果然，当我将'Dart'文件夹放回项目文件夹，修改了Web.config并刷新时 - 应用程序再次恢复为快照。

问题

当然，我的问题是，有人可以告诉我为什么在ServiceStack项目文件夹中嵌套Dart项目文件夹会导致ServiceStack.Razor停止呈现视图吗？

修改：更多信息

Dart文件夹包含以下文件类型：

  • pubspec.yaml
  • pubspec.lock
  • *。JS
  • *。镖
  • *。JSON
  • “web”文件夹中“packages”文件夹的快捷方式（DartEditor创建此文件）

仔细观察，/ packages下面的文件夹是系统缓存中原始库的符号链接（更多信息请参见：https://www.dartlang.org/tools/pub/faq.html）。

似乎ServiceStack正在绊倒这些符号链接。

答案 0 :(得分：1)

使用.NET的文件IO API无法在Windows中扫描符号链接时出现问题，而现在这些文件IO API已成为logged as warnings in this commit。此修复程序位于MyGet now或NuGet上的下一个 v4.0.13 + 中。
