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

I looked over the answers and didn't see the solution I found mentioned. If it was, my apologies. In my case, currently using Visual Studio 2015. In the solution explorer, right click on the Project file and click properties. Go to the Debug tab and this should have info for how you're launching "IIS Express or Web(DNX)" for the first two drop downs, and then there should be a checkmark box for "Launch URL:". Uncheck this option and your browser won't be automatically launched everytime you go to debug your application. Hope this helps someone out.

由于我的VS (Visual Studio Enterprise 2017)中没有上述选项，我不得不寻找其他选项。

以下是我的发现:

进入“工具->选项->调试”选项卡(通用)，取消选中“为Asp启用JavaScript调试”。Net(Chrome和IE)。

看起来2022年的维密秀已经改变了，

现在它有一个专门的用户界面，

右键单击项目(在解决方案资源管理器中)>选择属性，然后遵循:-

“uncheck”选项不自动打开。

或者您可以单击菜单栏，调试>属性

你可以直接从那里到达第二步“启动配置文件”

或者一个捷径:

选择项目(在解决方案资源管理器中)并按Alt + Enter，然后从那里开始。

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.
