我已经通过以下步骤解决了我的问题。 进入工具>>单击选项>>单击项目和解决方案>> web项目>> 取消“关闭浏览器时停止调试”选项

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.

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"
      }
    }
}

.NET核心Web Api项目的更新答案…

右键单击项目，选择“属性”，转到“调试”，取消“启动浏览器”复选框(默认启用)。

如果您在IIS中使用Web发布特性，那么我发现的解决方案是编辑发布配置并从配置中删除Destination URL(让它为空)。

如果定义了这个，那么每次发布项目时，它都会打开Destination URL中指定的URL(这是一个重定向URL)。

在Visual Studio 2019中，我解决了同样的问题:

去你的Visual Studio选项工具>>>选项>>>项目和解决方案>>> Web项目然后最后取消选项>>>停止调试器浏览器窗口关闭，关闭浏览器时调试停止

步骤1:

步骤2: >>>关闭调试器浏览器窗口，调试停止时关闭浏览器

步骤3:

最后点击>>> OK按钮，这些都是解决问题的步骤。
