Visual Studio 测试步骤成功完成后未报告代码覆盖率结果
Code coverage results not being reported after Visual Studio Test step completes successfully
我的 VSTS 帐户中有一个非常简单的项目，其中包含一些测试。我在构建中添加了一个 VsTest 步骤，并选中了代码覆盖框。但是，在我 运行 构建之后，它显示 "no code coverage results available" 并建议我向我的构建添加一个 Visual Studio 测试构建步骤。但是当我添加一个时，它与我已有的 VsTest 步骤相同。
如何从我的 VSTS 构建中获取代码覆盖率？
编辑：测试日志如下。有两部分有很多我无法复制和粘贴的特殊字符。

[编辑 2]：Starian Chen 要求将 System.Debug 设置为 true 的日志。它们超过了 SO 的大小限制，所以我在下面链接到它们：
编辑 3：当我在 VsTest 构建步骤的 "Other console options" 中指定框架时：
/framework:"Framework461"
好像对我的版本不满意。它给出了支持的框架列表，其中最高的是"Framework45."
编辑 4：我用 "Framework45" 尝试了一个 net452 项目。在那种情况下，测试通过 Starian Chen 的指示 here 进行了 运行，只是用 "Framework45" 代替了 "netcoreapp2.0"。但是，仍然没有代码覆盖率报告。
使用 .Net 框架测试项目，您无需在 Visual Studio 测试任务中指定框架和 vstest.console.exe 路径。
我的 VSTS 帐户中有一个非常简单的项目，其中包含一些测试。我在构建中添加了一个 VsTest 步骤，并选中了代码覆盖框。但是，在我 运行 构建之后，它显示 "no code coverage results available" 并建议我向我的构建添加一个 Visual Studio 测试构建步骤。但是当我添加一个时，它与我已有的 VsTest 步骤相同。

[编辑 2]：Starian Chen 要求将 System.Debug 设置为 true 的日志。它们超过了 SO 的大小限制，所以我在下面链接到它们：
编辑 3：当我在 VsTest 构建步骤的 "Other console options" 中指定框架时：
/framework:"Framework461"
好像对我的版本不满意。它给出了支持的框架列表，其中最高的是"Framework45."
编辑 4：我用 "Framework45" 尝试了一个 net452 项目。在那种情况下，测试通过 Starian Chen 的指示 here 进行了 运行，只是用 "Framework45" 代替了 "netcoreapp2.0"。但是，仍然没有代码覆盖率报告。
使用 .Net 框架测试项目，您无需在 Visual Studio 测试任务中指定框架和 vstest.console.exe 路径。
