Question

我们正在尝试将.Net 4.5项目（Web-Api）移植到.Net Core。

除了我之外，每个开发人员都可以使用它。此外，我们最近切换到VS 2017 RC。

程序启动但第一次请求崩溃：

-InnerException {System.TypeLoadException: Method 'get_ContentLength' in type 'Microsoft.AspNetCore.Server.Kestrel.Internal.Http.FrameRequestHeaders' 
 from assembly 'Microsoft.AspNetCore.Server.Kestrel, Version=1.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation.

我尝试了不同版本的Microsoft.AspNetCore.Server.Kestrel无济于事。删除并重置我所知道的VS的每个缓存并重新安装.NET Core和VS 2017 RC

Answer 1

通过还原

解决了这个问题

<PackageReference Include="Microsoft.AspNetCore.WebSockets" Version="1.1.0-preview1-23121" />

回到

<PackageReference Include="Microsoft.AspNetCore.WebSockets" Version="1.0.0" />

稳定的1.1.0版本仍然存在问题。

为什么它对某些开发人员起作用而不是为他人服务仍然是一种谜。

Answer 2

花了几个小时试图解决这个问题。解决方案正在更新到

"Microsoft.AspNetCore.Authentication.Google": "1.1.1"

在project.json中

。看似完全独立的包裹。如果有人被困，我会尝试搞乱其他依赖。

在.NET Core 1.1项目启动时，Microsoft.AspNetCore.Server.Kestrel中的TypeLoadException
