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
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
The Options
property of IOptions<T>
was renamed to Value
. Try:
_applicationSettings.Value
Also see this issue.
