Try this and it should work:

1-Go to your project folder and open .vs folder (keep your check hidden item-box checked as this folder may be hidden sometimes)

2- in .vs folder - open config

3- see that applicationhost config file there? Delete that thing.(Do not worry it will regenerate automatically once you recompile the project.)

In my case, it was not the application but what I was submitting. My form contained a file I was uploading and when I hit submit I would get that error. Turns out the file couldn't be uploaded because the file was in use. I just closed the file I was trying to attach and it worked.

blocks|key|2640658|text|对于VS+2019，如果您为您的项目设置了启用SSL，则会为您的项目创建两个URL+(URL和SSL+URL)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2640659|要解决此问题，请转到项目属性和网站:更新项目Url，创建虚拟目录并保存。|2640660|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

For the VS 2019, If you set SSL enabled for your project, there are two URLs create for your project (URL and SSL URL).
To fix this issue Go to project properties =&gt; Web: update the Project Url, Create virtual Directory and save.

Here's what I did. Right-click on the project and go to properties. Under the Debug tab uncheck and check Enable SSL. It will create a random url with port. Copy and paste the generated URL in the App URL. It worked for me fine there after.

I have an <code>asp.net</code> MVC project developed in VS2015. Now I try to run it in VS2017 and get an error:
