我遇到了以下问题。

Detected package downgrade: Microsoft.NETCore.App from 2.0.0-preview3-25514-02 to 2.0.0-preview2-006497

在具有以下csproj的项目上执行dotnet restore：

<Project Sdk="Microsoft.NET.Sdk.Web">

我做错了吗？

具体的错误信息如下：

error NU1605: Detected package downgrade: Microsoft.NETCore.App from 2.0.0-preview3-25514-02 to 2.0.0-preview2-006497. Reference the package directly from the project to select a different version.

答案 0 :(得分：0)

你有

<PackageReference Include="Microsoft.NETCore.App" Version="2.0.0-preview2-006497" />

在你的csproj中。但是因为你在所有其他版本上使用通配符

<PackageReference Include="Microsoft.AspNetCore.AzureAppServicesIntegration" Version="2.0.0-*" />

它试图获得每晚预览3。通常你不应该使用夜间构建，除非你知道你正在做什么，只是使用主要nuget源上发布的预览之一
