【问题描述】：

我有一个 ASP.Net Core 应用程序，其中包括主项目、两个库项目和一个单元测试项目。当我运行单元测试时，它会抱怨：

[7/14/2019 9:55:38 PM Informational] ------ Discover test started ------  
[7/14/2019 9:55:39 PM Warning] Test run will use DLL(s) built for framework .NETCoreApp,Version=v1.0 and platform X86. Following DLL(s) do not match framework/platform settings.

单元测试显然运行正确。我盯着我的项目配置，我已经阅读了引用的文章，但我无法弄清楚它在抱怨什么。我用谷歌搜索了错误消息，但我发现的内容似乎不适用于我的情况。

这是我的 csproj 文件 (FWIW)：

【问题讨论】：

它抱怨单元测试项目中使用的引用<ProjectReference Include="..\Indigo\Indigo.csproj" />。它的格式/框架不正确。
好吧，我放弃了……那个项目参考有什么不正确的地方？（要加分，请解释 Visual Studio 2017 如何设法创建无效的项目引用 [我现在正在使用 VS 2019]。要获得更多分，请解释为什么直到最近它才向我抱怨。甚至更多分，解释为什么人们不赞成这个问题。）

【解决方案1】：

这个问题似乎在 Visual Studio 16.2.2 中得到修复。

【讨论】：

在 VS 16.4.2 中遇到完全相同的问题。我在解决方案中添加的第一个测试项目很好。我添加的第二个测试项目我得到“测试运行将使用为框架 .NETCoreApp,Version=v1.0 和平台 X86 构建的 DLL。以下 DLL 与框架/平台设置不匹配。IntegrationTests.dll是为 Framework.NETCoreApp,Version=v3.1 和 Platform AnyCPU”构建的。尝试删除项目并重新添加，创建新项目，清理解决方案，重新启动 VS，似乎没有任何效果。

【解决方案2】：

我刚刚从 Visual Studio 16.1.x 更新到 16.3.3，我遇到了类似的问题。我通常使用“.runsettings”文件运行我的测试，我发现我必须做两件事：

从“.runsettings”文件中删除<TargetFrameworkVersion> 设置。
在“构建”菜单中，运行“清洁解决方案”。（没有这个，测试运行器的结果将不会显示在测试资源管理器中。）

【解决方案3】：

我最近在 VS 2019 16.5.2 上遇到了这个问题 - 结果项目已更新到 Microsoft.NET.Test.Sdk 16.5 - 降级到 16.2 解决了我的问题。我通过一次成功降级一个版本获得了 v16.2。 16.4 等等。

似乎 Microsoft.NET.Test.Sdk 16.5 需要 NET Core 3.0+
