为什么 VS2005 中的 Web 应用程序项目提供“转换为 Web 应用程序”选项？菜单选择
我相信我完全理解 Visual Studio 2005 的网站模型与 VS2005 SP1 中完全交付的 Web 应用程序项目模型之间的差异 - 但我遇到了一件令人困惑的事情：
我有一个我编写的 Web 应用程序项目（它有一个 bin包含已编译的projectname.dll 和引用的.dll 的文件夹，等等）。但我刚刚注意到，如果我在解决方案资源管理器中右键单击该项目，则会显示一个名为“转换为 Web 应用程序”的菜单项）。这对我来说毫无意义。
我正在将该项目与 VS2005 中的“网站”解决方案进行比较，并考虑将其转换为 Web 应用程序项目。奇怪的是，解决方案资源管理器没有提供任何与“转换为 Web 应用程序”相关的内容，就像人们认为可能和/或适当的那样。
我的结论是，没有什么可以帮助自动将“网站”构造更改为正确的“Web 应用程序项目”。我认为这一切都必须手工完成。将 App_Code 中的文件重新构建为一个或多个类库项目等任务需要手动完成。
我意识到已经写了很多关于历史和差异的文章，但有人可以解释为什么“转换为网络应用程序”的提议似乎是在“错误”的模型中进行的 - 并且只需确认转换是手动的。
I believe I understand fully the differences between Visual Studio 2005's web site model versus the web application project model that was fully delivered in VS2005 SP1 - but I have run into a confusing thing:
I have a web application project I wrote (it has a bin folder with the compiled projectname.dll and referenced .dlls too, etc.). but I just noticed that if I right-click on the project within Solution Explorer, a menu item called "Convert to Web Application" is exposed). That makes no sense to me.
I was comparing this project to a "web site" solution in VS2005 and contemplating converting it to a web application project. Strangely, the solution explorer offers nothing related to "Conversion to Web App" here like one would think is possible and/or appropriate.
I conclude there is nothing to help automate changing a "web site" construct to a proper "web application project". I assume it all has to be done by hand. Tasks such as reconstituting files in App_Code into one or more class library projects needs to be done manually.
I realize a lot has been written about the history and differences but can someone explain why the offer to "convert to web app" seems to be made in the "wrong" model - and just confirm that conversion is manual.

转换向导做得不错 - 即，该过程远非严格的手动 - 但您仍然需要花费大量时间从网站转移到 Web 应用程序模型。
aspx 页面的“转换为 Web 应用程序”上下文菜单选项会生成一个 myclass.designer.cs 文件，该文件将标记中定义的控件与代码隐藏类联系起来，从而允许智能感知、编译时验证、和其他事情。
对项目文件执行此操作应该为项目中的所有 aspx 生成设计器文件，并且我相信还会创建一些默认应用程序设置，例如程序集名称等，这些设置未在输出为源的网站项目中定义，不是程序集。
The conversion wizard does a decent job -ie, the process is far from being strictly manual - but you're still going to spend a lot of time moving from the website to web application model.
The "Convert to Web Application" context menu option for aspx pages generates a myclass.designer.cs file, which ties controls defined in markup back to the codebehind class, allowing for intellisense, compile-time validation, and other things.
Performing this action on a project file should generate designer files for all of the aspx's in the project, and I believe also creates some default application settings such as assembly name, etc, that aren't defined in a website project where the output is source, not an assembly.
我猜测您编写的“Web 应用程序”没有以正确的 vsproj 文件开头。如果您引入的项目没有正确的文件系统方案 .aspx、aspx.cs、aspx.designer.cs，则 Visual Studio 会假设您正在尝试创建“Web 应用程序”并为您提供转换特征。
早在 2005 年，Scott Guthrie 就制作了一个有关将网站项目转换为 Web 应用程序项目的教程。这是关于从网站项目迁移到 Web 应用程序项目的部分 。
I'm going to guess that the 'web application' that you wrote didn't start out with the correct vsproj file. If you bring in a project that doesn't have the correct file system scheme .aspx, aspx.cs, aspx.designer.cs then visual studio will assume that you're trying to create a 'web application' and gives you that conversion feature.
Back in 2005, Scott Guthrie did a tutuorial about converting a web site project to a web application project. Here is the section about Migrating from a Web Site Project to a Web Application Project.
