调试ASP.NET（.NET Framework 4.8）Web应用程序时，没有以新的csproj格式为（.NET Framework 4.8）库加载任何符号

Question

我有一个已经开发并发展了多年的ASP.NET（.NET Framework 4.8）Web应用程序。

我花了一些时间将它使用的许多类库转换为新的csproj格式，但类库仍以.NET Framework 4.8（net48）为目标。

应用程序编译并运行良好。但是，我刚刚尝试调查问题，发现在调试时，不再为转换后的类库加载符号，并且我无法再逐步浏览这些类库中的代码。

转换后的类库的典型.csproj如下：

不变的ASP.NET Web应用程序仍然是旧格式，因为Microsoft仍未提供对新的csproj格式的支持（尽管几年前就已经这样做了）。它看起来像这样：

有什么方法可以使类库在调试器中完全起作用？还是我必须有点生气然后“撤消”所有转换工作？

编辑：因此，在另一台计算机上，我创建了一个新的ASP.NET Framework Web App和两个类库（一个.NET Framework 4.7.2和一个.NET Standard 2.1。）。我能够进入这两个类库，因此这似乎不是由于新的csproj格式本身引起的。

回到我有问题的解决方案，我可以看到.NET Standard Class lib在bin文件夹中有一个.PDF文件，但调试器输出显示：

跳过的加载符号。模块已优化，调试器选项“仅我的代码”已启用

仅启用我的代码，但是我认为“模块已优化”是真正的问题。我正在编译为DEBUG而不是Release。我需要在“ .NET Standard Class Lib” .csproj文件中进行更改以编译DEBUG版本而不进行优化的任何想法吗？

谢谢克里斯

Answer 1

因此，如开头问题中所述，“构建输出”显示这些模块未加载符号，因为输出已“优化”（GB已优化）。

“项目属性”页面的“构建”选项卡包括两个复选框：“定义DEBUG常量”和“优化代码”。当查看DEBUG配置时，第一个未选中，第二个已选中。

颠倒这两个问题（DEBUG配置）解决了所提出的问题。但是，“优化代码”似乎不是特定于配置的，并且在更改后查看基础的csproj文件，我可以看到它是在配置之外定义的：

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        ...
        <TargetFramework>net48</TargetFramework>
        <Optimize>false</Optimize>                  <-- Not Configuration specific
        <LangVersion>8.0</LangVersion>
    </PropertyGroup>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
        <DebugType>full</DebugType>
        <DebugSymbols>true</DebugSymbols>
        <DefineConstants>DEBUG</DefineConstants>    <-- Configuration specific
    </PropertyGroup>

[我发现我可以添加“ Release | AnyCPU”配置/平台并移动每个版本中的<Optimize>值来解决此问题：

        <LangVersion>8.0</LangVersion>
