更新到ASP NET 5 beta5会破坏一切 [英] Updating to ASP NET 5 beta5 breaks everything

问题描述

在更新到beta5时，我遵循了本指南，并且更新过程似乎已经奏效.

I followed this guide when updating to beta5 and the update process seems to have worked.

要更新到ASP.NET 5 Beta5，请使用以下步骤:

To update to ASP.NET 5 Beta5 use the following steps:

• 如果尚未安装.NET版本管理器(DNVM)(它已随Visual Studio 2015 RC预先安装)，则可以 获取最新版本)
• 在命令提示符下，将DNX_FEED环境变量设置为 https://www.nuget.org/api/v2
• 运行"dnvm升级"，在您的应用程序中更新global.json以指向beta版本的.NET执行环境(DNX)
• 您的project.json也指向beta5软件包版本
• 运行"dnu restore"运行"dnu build"并将代码迁移到所需的beta5

• Install the .NET Version Manager (DNVM) if you don’t already have it (it comes preinstalled with Visual Studio 2015 RC, or you can get the latest version)
• From a command prompt set the DNX_FEED environment variable to https://www.nuget.org/api/v2
• Run "dnvm upgrade" In your app update your global.json to point to beta5 version of the .NET Execution Environment (DNX)
• Also your project.json to point to the beta5 package versions
• Run "dnu restore" Run "dnu build" and migrate your code to beta5 s needed

但是，我遇到构建错误，提示我缺少程序集.它抱怨System.Void，而这样的东西丢失了.它还无法从Microsoft.AspNet.MVC中找到Controller:/

However I'm getting build errors that says I have missing assemblies. It complains about System.Void and such is missing. It also can't find Controller from Microsoft.AspNet.MVC :/

如果我恢复为beta4，则它将再次正常工作.

If I revert back to beta4 then it works again.

我错过了哪一步?

推荐答案

我刚刚将Visual Studio 2015 ASP.MVC Web应用程序从beta4升级到beta5，现在可以运行它了.这是您遵循的说明的一些补充.

I just upgraded a Visual Studio 2015 ASP.MVC Web Application from beta4 to beta5 and now have it running. Here are some additions to the instructions that you followed.

执行完此操作后，将输出dnvm list.

After doing that, this is what dnvm list will output.

Active Version           Runtime Architecture Location                       Alias
------ -------           ------- ------------ --------                       -----
       1.0.0-beta4       clr     x64          C:\Users\BigFont\.dnx\runtimes
       1.0.0-beta4       clr     x86          C:\Users\BigFont\.dnx\runtimes
       1.0.0-beta4       coreclr x64          C:\Users\BigFont\.dnx\runtimes
       1.0.0-beta4       coreclr x86          C:\Users\BigFont\.dnx\runtimes
  *    1.0.0-beta5       clr     x86          C:\Users\BigFont\.dnx\runtimes default
       1.0.0-beta5-12087 clr     x86          C:\Users\BigFont\.dnx\runtimes

在您的应用中，更新您的global.json以指向beta5

在 global.json 指向beta5的特定版本:

{
    "projects": [ "src", "test" ],
    "sdk": {
        "version": "1.0.0-beta5"
    }
}

您的project.json也指向beta5软件包版本

在 project.json 参考beta5.这将使dnu恢复最新的版本(好吧，有点-David Fowl在这里描述了浮动版本"的细微差别.)

Also your project.json to point to the beta5 package versions

In project.json reference beta5. That will make dnu restore the most recent build (well, kinda - David Fowl describes the nuances of the "floating version" here.)

"dependencies": {
  "Microsoft.AspNet.Server.IIS": "1.0.0-beta5",
  "Microsoft.AspNet.Server.WebListener": "1.0.0-beta5",
  "Microsoft.AspNet.StaticFiles": "1.0.0-beta5"
},

...根据需要将代码迁移到beta5

一旦停止接收到有关缺少基本对象(如System.Void)的错误，则可能会收到有关中断更改的错误.这可能需要一些研究来解决，具体取决于您的代码库使用什么.例如，如果您使用的是ASP.NET Identity，则需要更改以下内容:

...migrate your code to beta5 as needed

Once you've stopped received errors about missing fundamental objects like System.Void, you might receive errors about breaking changes. This could take some research to solve, depending on what your code base uses. For instance, if you're using ASP.NET Identity, you'll need to change this:

SignInManager.PasswordSignInAsync(
    model.Email, model.Password, model.RememberMe, shouldLockout: false);

对此:

SignInManager.PasswordSignInAsync(
    model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);

最终注释:Visual Studio

在更新global.json和package.json文件之后，在Visual Studio中关闭并重新打开该解决方案可以解决还原/生成问题.

Final note re: Visual Studio

Closing and reopening the solution in Visual Studio can resolve restore/build problems after updating global.json and package.json files.
