c# - 调试 ASP.NET (.NET Framework 4.8) Web 应用程序时，没有为新 csproj 格式的 (.NET Framework 4.8) 库加载符号

问题描述

我有一个我们多年来一直在开发和发展的 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，但类库仍然以 .NET Framework 4.8 (net48) 为目标。

该应用程序编译并运行良好。但是，我刚刚尝试调查一个问题，发现在调试时，不再为转换后的类库加载符号，我无法再单步执行这些类库中的代码。

转换后的类库的典型 .csproj 如下：

未更改的 ASP.NET Web 应用程序仍然是旧格式，因为 Microsoft 仍然没有引入对新 csproj 格式的支持（尽管几年前就已经谈过了）。它看起来像这样：

有什么办法可以让类库在调试器中充分工作？还是我将不得不有一点愤怒，然后“撤消”所有的转换工作？

编辑：所以在一台单独的机器上，我创建了一个新的 ASP.NET Framework Web 应用程序和两个类库（一个 .NET Framework 4.7.2 和一个 .NET Standard 2.1）。我能够进入两个类库，所以这似乎不是由于新的 csproj 格式本身。

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

跳过加载符号。模块已优化并启用了调试器选项“仅我的代码”

Just My Code 已启用，但我认为“模块已优化”是真正的问题。我正在编译为 DEBUG 而不是 RELEASE。关于我需要在“.NET Standard Class Lib”.csproj 文件中更改哪些内容以编译 DEBUG 版本而不进行优化的任何想法？

谢谢克里斯

标签： c#asp.net.net-4.0

解决方案

因此，如开头问题所述，构建输出显示这些模块不加载符号，因为输出已“优化”（GB 优化）。

Project Properties 页面的 Build Tab 包括两个复选框：“Define DEBUG constant”和“Optimize code”。在查看调试配置时，第一个未被选中，第二个被选中。

反转这两个（调试配置）解决了提出的问题。但是，“优化代码”似乎不是特定于配置的，并且在更改后查看底层 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>

我发现我可以添加一个“Release|AnyCPU”配置/平台并移动<Optimize>每个版本中的值来解决这个问题：

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <ProductVersion>9.0.30729</ProductVersion>
        <SchemaVersion>2.0</SchemaVersion>
        <OutputType>Library</OutputType>
        <AppDesignerFolder>Properties</AppDesignerFolder>
        <TargetFramework>net48</TargetFramework>
        <SccProjectName>SAK</SccProjectName>
        <SccLocalPath>SAK</SccLocalPath>
        <SccAuxPath>SAK</SccAuxPath>
        <SccProvider>SAK</SccProvider>        <-- Removed <Optimize> from here
        <LangVersion>8.0</LangVersion>
    </PropertyGroup>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">    <-- ADDED
        <DebugType>full</DebugType>
        <DebugSymbols>true</DebugSymbols>
        <Optimize>true</Optimize>             <-- ADDED
    </PropertyGroup>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
        <DebugType>full</DebugType>
        <DebugSymbols>true</DebugSymbols>
        <DefineConstants>DEBUG</DefineConstants>
        <Optimize>false</Optimize>            <-- ADDED
    </PropertyGroup>
