.net core源码调试前的配置

一直想想研究.net core的源码，参照 solenovex大牛的方法，最后终于成功启动了.net core源码，过程如下：

1、powershell定位到 X:aspnetcoreengscripts，运行其中的InstallVisualStudio.ps1，在弹出的VS修改安装界面后，直接点修改，安装完成后关闭即可。

2、cmd定位到X:aspnetcore目录下，运行restore.cmd，此时会下载一个目录X:aspnetcore.dotnet，关闭cmd窗口停止restore进程，编辑目录下的dotnet-install.ps1文件，

把

Say "Downloading link: $DownloadLink"
try {
DownloadFile -Source $DownloadLink -OutPath $ZipPath

修改成

Say "Downloading link: $DownloadLink,$ZipPath"
try {
while(![System.IO.File]::Exists($ZipPath)){
Start-Sleep -s 5
}
Say "$ZipPath is has exists"
# DownloadFile -Source $DownloadLink -OutPath $ZipPath

作出上面修改的原因是，powershell可能是单线程下载或网络原因（你懂的），

DownloadFile -Source $DownloadLink -OutPath $ZipPath 这句话是下载安装包 ，我们注释掉它，不让它下载，

Say "Downloading link: $DownloadLink,$ZipPath" 中的$DownloadLink是远程下载地址，$ZipPath是临时文件路径，知道了这两个地址后用循环判断，如果文件不存在就休眠5秒，这时我们可以用多线程下载工具或浏览器下载远程地址的文件，下载完成后复制到临时目录改成$ZipPath的临时文件名，然后线程就会解压文件进行安装，这样就不用等很久才能下载安装包。

3、restore有可能会有些文件没下载会，也可以在cmd下执行build.cmd命令，估计作用和restore.cmd是一样的。

4、成功后还要修改D:aspnetcoresrcComponentsServersrcMicrosoft.AspNetCore.Components.Server.csproj  具体问题看 https://github.com/dotnet/aspnetcore/pull/18713/files/9142fbf5940c4c8cd8cc66f50fe63569f50747e0#diff-8d3e3b66d47490ce28ba798996aea5ec

修改成如下内容，对照修改下面绿色粗体内容

5、这时可以打开 其中的源码解决方案，比如 X:aspnetcoresrcMvc ，双击这个目录下的startvs.cmd ，会调用VS打开 MVC.sln并还原依赖的包，直接打开MVC.sln好像无法加载项目，我以后再试。

6、如果正常打开项目，可以试着生成解决方案，如果生成成功，那么调试就没问题了。默认是test目录下的BasicWebSite项目为启动项目的，你也可以修改其它项目为启动项目。

7、.net core源码调试成功，记下解决经历以备忘也可以帮助到其他的人。
