您可以使用“附加到进程”功能，而不是按F5。

这也可以让你在已知的工作部分中导航，而不会在下面加载VS调试器。

您现在还可以通过单击Run按钮旁边的下拉箭头来访问Web属性!

点击“运行”旁边的下拉按钮 {项目名称}属性 点击左侧列表中的“Web” 在“开始操作”段下，单击“不打开页面”。

你都准备好了!

PS:这对我来说是有效的，我使用的是VS Professional 2019的16.5.5版本:)

VS 15.7.1工具→选项→项目和解决方案→Web项目→取消勾选关闭浏览器窗口时停止调试器。

Joao Costa的答案同样适用于。net core 2项目。

launchsettings。json——> "launchBrowser": false

"profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": false,
      "environmentVariables": {
        "Hosting:Environment": "Development"
      }
    }
}

There seems to be one case in which none of the above but the following helps. I'm developing a project for Windows Azure cloud platform and I have a web role. There is indeed a radio button Don't open page in Project -> {Project name} properties... as was pointed out by Pawel Krakowiak, but it has no effect in my case whatsoever. However, there is the main cloud project in solution explorer and there is the Roles folder under it. If I right click my web role in this folder and choose Properties, I get another set of settings and on the Configuration tab there is the Launch browser for flag, after unchecking it a new browser window is not opened on application start up.

以下是对我有用的方法:

去项目属性>调试>取消“启动浏览器”>保存。
