IOptions<应用>在ASP.NET 5 Beta 8中不包含定义“选项” [英] IOptions<Applications> does not contain definition 'Options' in ASP.NET 5 Beta 8

问题描述

问题

我将beta7应用升级到beta8时遇到问题。我原来已经有超过50个错误，但是我基本上得到了两个持续的错误，我一直无法解决。一个是选项。

选项缺少错误

这是错误：

错误CS1061'IOptions< ApplicationSettings>'不包含'Options'的定义，没有扩展方法'Options'接受'IOptions'类型的第一个参数， ApplicationSettings>'可以找到（你是否缺少一个using指令或程序集引用？）SampleProject.DNX 4.5.1

这里是代码：

  private IOptions< ApplicationSettings> _applicationSettings; 
 
 //验证Active Directory的用户凭据
 bool isAuthenticated = await Authentication.ValidateCredentialsAsync（
 domainController：_applicationSettings.Options.DomainController，
 port：_applicationSettings.Options。 DomainControllerSslPort，
域：_applicationSettings.Options.DomainController，
用户名：model.eID，
密码：model.Password）; 
  

上面的具体问题是使用 _applicationSettings.Options.DomainController

尝试：

我尝试过以下操作： p>

• 我尝试使用智能感知和GitHub来查找IOptions的选项的位置，但我一直没有成功。


• 我还尝试了 dnu restore 只是为了确保升级没有对我的project.json锁做一些奇怪的事情。

现在beta8功能完整，我可能会重写我项目的重要部分。但是，现在我需要解决这些错误，以便我可以再次编译该项目。任何帮助，协助和建议将不胜感激。

注意：我根据反馈编辑了一个问题

解决方案

选项属性 IOptions< T> 已重命名为值。尝试：

  _applicationSettings.Value

Problem

I am having trouble with upgrading my beta7 application to beta8. I orginally had over 50 errors, but I have basically gotten it down to two persistent errors remaining that I have been unable to resolve. One is with Options.

Options Missing Error

Here is the error:

Error CS1061 'IOptions<ApplicationSettings>' does not contain a definition for 'Options' and no extension method 'Options' accepting a first argument of type 'IOptions<ApplicationSettings>' could be found (are you missing a using directive or an assembly reference?) SampleProject.DNX 4.5.1

Here is the code:

private IOptions<ApplicationSettings> _applicationSettings;

// Authenticate user credentials against Active Directory
bool isAuthenticated = await Authentication.ValidateCredentialsAsync(
                domainController: _applicationSettings.Options.DomainController,
                port: _applicationSettings.Options.DomainControllerSslPort,
                domain: _applicationSettings.Options.DomainController,
                username: model.eID,
                password: model.Password);

The specific problem above is with _applicationSettings.Options.DomainController

Attempts:

I tried the following things:

• I tried using intellisense and GitHub to find where 'Options' for IOptions went, but I have been unsuccessful.
• I also tried dnu restore just to be sure the upgrade didn't do something strange with my project.json lock.

Now that beta8 is feature complete, I may rewrite significant portions of my project. However, for now I need to resolve these errors so that I can compile the project again. Any help, assistance, and advice rendered would be greatly appreciated.

Note: I edited this to one question based on feedback

解决方案

The Options property of IOptions<T> was renamed to Value. Try:

_applicationSettings.Value
