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。

在ASP中。Net 5项目现在可以为每个启动配置文件设置。

打开文件launchsettings。在Startup Project Properties文件夹下添加"launchBrowser": false到你正在配置的配置文件中，例如:

"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.

这个变通方法对我来说适用于VS 2019

工具=>选项

然后在搜索框中键入项目和解决方案。

选择Web项目。

然后取消下面的选项。

关闭浏览器窗口时停止调试器，调试停止时关闭浏览器。

这对我很有用。希望这能有所帮助。
