System.Threading.Tasks 和 System.Runtime 中的任务冲突

Question

我在 asp.net 核心中有一个中间件，它工作正常，但现在它给出以下错误

“Task”类型存在于“System.Threading.Tasks, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”和“System.Runtime, Version=4.2.0.0, Culture=neutral, PublicKeyToken= b03f5f7f11d50a3a' ERP..NETCoreApp,Version=v1.1

我也尝试了别名和绝对引用，但没有成功。

这是 Project.json

{
  "dependencies": {
    "AutoMapper": "5.2.0",
    "Microsoft.AspNetCore.Diagnostics": "1.1.0",
    "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.1.0",

Answer 1

我能够解决此更改 Debug 软件包版本。

"Microsoft.Extensions.Logging.Debug": "1.2.0-preview1-23015",

到

"Microsoft.Extensions.Logging.Debug": "1.1.0",

并且还要更改 Invoke 方法签名

public Task Invoke(HttpContext httpContext)

到

public async Task Invoke(HttpContext httpContext)
