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，工作正常，但现在它给出了以下错误

  

类型＆＃39;任务＆＃39;存在于System.Threading.Tasks，Version = 4.0.10.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃39;和＆＃39; System.Runtime，Version = 4.2.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃39; ERP..NETCoreApp，版本= 1.1版

我尝试了别名和绝对引用，但它没有用。

这是Project.json

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

Answer 1

我能够解决Debug包版本的这一变化。

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

要

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

并在Invoke方法签名中进行更改

public Task Invoke(HttpContext httpContext)

要

public async Task Invoke(HttpContext httpContext)
