一、前言
最近我在使用 WinDebug进行系统调试，也是在学习《Net高级调试》这本书。以前听过 WinDebug 调试器，但是没有使用过，由于最近想起来了，就好好的研究一下，学习一下。初次接触，还是走了不少弯路，踩了不少坑。关于 WinDebug 最新版的安装方法，可以在“微软商店”里面，直接查询“WinDebug”，找到后，点击安装就好。当然都是在线安装的，没有网络是不行的。来一个截图把，先有一个直接的感觉，截图如下：
这次的调试环境和平台如下：
操作系统：WIndows 10 Professinal
开发工具：Visual Studio 2019
开发语言：C#
框架平台：Net Framework 4.8
调试工具：Windebug Preview
二、开始我们的入门之旅吧
由于我也是第一次使用 Windebug 进行系统调试，所以就免不了采一些坑。我安装好Windebug 软件，尝试加载 VS2019 创建的一个控制台项目，说明一下，不是跨平台版本，但是就是没有办法获取我想要的东西，后来，仔细对比，才发现，没有加载 SOS.DLL，所以使用命令也不起作用。今天我们就解决一下，如何让 Windebug 加载 Net Core 版本的 SOS.DLL。 .NET Framework 和 DotNet Core 版本不相同的是，当前的 SOS.dll 是放在独立的 https://github.com/dotnet/diagnostics 仓库里面，也需要独立安装。好在 SOS 通过 DotNet Tool 进行分发，安装方法也非常简单。
1、使用以下命令进行安装，在命令行工具中。
dotnet tool install -g dotnet-sos
安装很简单，执行命令就可以，我的直接安装就成功了，
2、以上是添加 DotNet SOS 工具，接下来还需要调用此工具进行安装，请在命令行输入下面命令进行安装。
dotnet sos install
C:\Users\Administrator>dotnet sos install Installing SOS to C:\Users\Administrator\.dotnet\sos Creating installation directory... Copying files from C:\Users\Administrator\.dotnet\tools\.store\dotnet-sos\7.0.410101\dotnet-sos\7.0.410101\tools\net6.0\any\win-x64 Copying files from C:\Users\Administrator\.dotnet\tools\.store\dotnet-sos\7.0.410101\dotnet-sos\7.0.410101\tools\net6.0\any\lib Execute '.load C:\Users\Administrator\.dotnet\sos\sos.dll' to load SOS in your Windows debugger. SOS install succeeded
截图效果：
3、通过以下命令让 WinDebug 加载 SOS 文件。
.load C:\Users\Administrator\.dotnet\sos\sos.dll
The call to LoadLibrary(C:\Users\lindexi\.dotnet\sos\sos.dll) failed, Win32 error 0n193 "%1 不是有效的 Win32 应用程序。
4、此时的解决方法是去获取 x86 版本的 sos.dll ，我的命令的位置如下：
C:\Users\Administrator\.dotnet\tools\.store\dotnet-sos\7.0.410101\dotnet-sos\7.0.410101\tools\net6.0\any\win-x86
需要自己去找放在 C:\Users\Administrator\.dotnet\tools\.store\dotnet-sos\7.0.410101\dotnet-sos\7.0.410101\tools\net6.0\any\win-x86\ 文件夹的对应的 dotnet 版本的 sos 的 win-x86 版本的文件。
5、WinDebug 成功加载 Sos，我们就可以使用了，在 WinDebug 中，通过命令 .chain 命令，就可以看到结果了，红色部分表示加载了SOS.dll。

6、我们也可以查看 SOS的帮助命令，执行命令：!sos.help 命令，如下：

7、我们也可以查看堆的具体情况，执行命令：!dumpheap -stat 命令，如下：
1 0:000> !dumpheap -stat 2 *** WARNING: Unable to verify checksum for 01、PatrickLiu.AdvanceDebug.DebugTools.exe 3 Statistics: 4 MT Count TotalSize Class Name 5 6ecf5468 1 12 System.Collections.Generic.GenericEqualityComparer`1[[System.String, mscorlib]] 6 6ecf4888 1 12 System.Security.HostSecurityManager 7 6ecf3d78 1 12 System.Collections.Generic.ObjectEqualityComparer`1[[System.Type, mscorlib]] 8 6ed59b0c 1 16 System.IO.TextReader+SyncTextReader 9 6ecf480c 1 16 System.Security.Policy.Evidence+EvidenceLockHolder 10 6ecf1848 1 16 System.Security.Policy.AssemblyEvidenceFactory 11 6ecf9098 1 20 Microsoft.Win32.SafeHandles.SafeFileMappingHandle 12 6ecf9048 1 20 Microsoft.Win32.SafeHandles.SafeViewOfFileHandle 13 6ecf8fb4 1 20 System.Text.InternalEncoderBestFitFallback 14 6ecf89dc 1 20 System.IO.Stream+NullStream 15 6ecf1790 1 20 Microsoft.Win32.SafeHandles.SafePEFileHandle 16 6ecf9004 1 24 System.Text.InternalDecoderBestFitFallback 17 6ecf8c64 1 24 System.IO.TextWriter+SyncTextWriter 18 6ecf5160 1 24 System.Version 19 6ed5b818 1 28 System.Text.DBCSCodePageEncoding+DBCSDecoder 20 6ecf91c0 1 28 System.Text.EncoderNLS 21 6ecf8b20 1 28 Microsoft.Win32.Win32Native+InputRecord 22 6ecf4cc0 1 28 System.Text.UTF8Encoding+UTF8EncodingSealed 23 6ecf27d0 1 28 System.SharedStatics 24 6ecf4b60 2 32 System.Text.DecoderReplacementFallback 25 6ecf4b10 2 32 System.Text.EncoderReplacementFallback 26 6ecf48fc 1 32 System.Text.UnicodeEncoding 27 6ecf17f0 1 32 System.Security.Policy.PEFileEvidenceFactory 28 6ecf2ef0 1 36 System.Security.PermissionSet 29 6ecf4c34 2 40 Microsoft.Win32.SafeHandles.SafeFileHandle 30 6ecf2e6c 1 40 System.Security.Policy.Evidence 31 6ed5c4b8 1 44 System.Text.InternalEncoderBestFitFallbackBuffer 32 6ecf4680 1 44 System.Threading.ReaderWriterLock 33 6ecf52a0 1 48 System.Collections.Generic.Dictionary`2[[System.String, mscorlib],[System.Globalization.CultureData, mscorlib]] 34 6ecf4ec0 1 48 System.Collections.Hashtable+bucket[] 35 6ecf42a8 4 48 System.Int32 36 6ecf304c 1 48 System.Collections.Generic.Dictionary`2[[System.Type, mscorlib],[System.Security.Policy.EvidenceTypeDescriptor, mscorlib]] 37 6ecf16f0 4 48 System.UInt16 38 6ecf4e00 1 52 System.Collections.Hashtable 39 6ecf3de0 1 52 System.Type[] 40 6ecf2e10 1 52 System.Threading.Thread 41 6ecf8b68 2 56 System.IO.__ConsoleStream 42 6ecf524c 2 56 System.Text.StringBuilder 43 6ecf46c8 2 56 System.Reflection.RuntimeAssembly 44 6ecf59a8 1 60 System.IO.StreamWriter 45 6ecf55bc 1 60 System.Collections.Generic.Dictionary`2+Entry[[System.String, mscorlib],[System.Globalization.CultureData, mscorlib]][] 46 6ed3dc64 1 64 System.IO.StreamReader 47 6ecf2b94 1 68 System.AppDomainSetup 48 6ecf4f50 1 72 System.IO.UnmanagedMemoryStream 49 6ed5bcc4 1 76 System.Text.DBCSCodePageEncoding 50 6ecf520c 1 84 System.Globalization.CalendarData 51 6ecf26b4 1 84 System.ExecutionEngineException 52 6ecf2670 1 84 System.StackOverflowException 53 6ecf2628 1 84 System.OutOfMemoryException 54 6ecf25d4 1 84 System.Exception 55 6ecf2734 8 96 System.Object 56 6ecf51c8 1 104 System.Globalization.CalendarData[] 57 6ecf2810 1 112 System.AppDomain 58 01308d50 10 116 Free 59 6ecf5700 1 132 System.Globalization.NumberFormatInfo 60 6ecf5074 2 144 System.Globalization.CultureInfo 61 6ecf26f8 2 168 System.Threading.ThreadAbortException 62 6ecf44d4 3 468 System.Collections.Generic.Dictionary`2+Entry[[System.Type, mscorlib],[System.Security.Policy.EvidenceTypeDescriptor, mscorlib]][] 63 6ecf426c 11 564 System.Int32[] 64 6ecf2d74 18 608 System.String[] 65 6ecf512c 2 616 System.Globalization.CultureData 66 6ecf3698 26 728 System.RuntimeType 67 6ecf5c40 3 806 System.Byte[] 68 6ecf2c60 10 2986 System.Char[] 69 6ecf24e4 166 6292 System.String 70 6ecf2788 6 17748 System.Object[] 71 Total 332 objects
8、如果我们想运行调试，可以执行g命令，然后再点击【Break】命令，切换到：~0s，执行调试，如下：
9、如何我们想查看托管堆的布局，可以执行命令：!eeheap -gc 命令，如下：
1 0:000> !eeheap -gc 2 Number of GC Heaps: 1 3 generation 0 starts at 0x02441018 4 generation 1 starts at 0x0244100c 5 generation 2 starts at 0x02441000 6 ephemeral segment allocation context: none 7 segment begin allocated size 8 02440000 02441000 02445ff4 0x4ff4(20468) 9 Large object heap starts at 0x03441000 10 segment begin allocated size 11 03440000 03441000 03445558 0x4558(17752) 12 Total Size: Size: 0x954c (38220) bytes. 13 ------------------------------ 14 GC Heap Size: Size: 0x954c (38220) bytes.
截图如下：
10、如何我们想查看帮助文档，可以执行命令：.hh，注意，前面有英文点号。
11、我自己重新下载了 SOSEX.Dll，然后使用 load 命令加载到 Windebug 中。红色表示要执行的命令。

12、可以使用 !sosex.help 命令，查看 SOSEX的帮助文件。红色表示要执行的命令。

14、使用 !mlocks 命令，查看是否有死锁问题。

15、我们可以使用 qq 命令退出 Windebug 。红色字体表示要执行的命令。

三、结束语
学无止境，还有很多，以后会慢慢来的。不学不知道，一学吓一跳，发现很多以前概念性的东西，现在变得更具体得了，知道托管堆是什么样子了。但是学的越多，好像懂得越少，没办法，我们只能无限努力，不忘初心，重新启程。老天不会辜负努力的人。
天下国家,可均也；爵禄,可辞也；白刃,可蹈也；中庸不可能也
