对于VS2022和ASP。NET核心:

另一个快捷方式是:单击右边绿色三角形按钮上的小下拉按钮，上面有项目名称，这通常会启动调试版本。然后是最后一个选项“{项目名}调试属性”，它直接启动专用的UI窗口。

从那里遵循@irf的建议:

“uncheck”选项不自动打开。

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)。

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。

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.
