Specified argument was out of the range of valid v

Question

I am getting this Kind of Error like::

Specified argument was out of the range of valid values.Parameter name: site

while Debugging any of my Project.

I have also tried after Reinstalling My Visual Studio 2012. But again the same kind of problem I am getting while Debugging.

My System's Configurations are :

Exception is thrown at the time of Showing Web Page Like,

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: site]

Answer 1

When you start with a Specific Page while debugging your project, and you are using Local IIS, you might have filled a wrong value in the Specific Page textbox.

(via Project Properties > Web > Start Action > Specific Page)

Wrong configuration:

Specific Page: "http://localhost/MyApplication/Start/SpecificPage.aspx"
Project Url: "http://localhost/MyApplication"

Right configuration:

Specific Page: "/Start/SpecificPage.aspx"
Project Url: "http://localhost/MyApplication"

Note: Ignore the quotation marks.

Answer 2

I had the same issue with VS2017. Following solved the issue.

1. Run Command prompt as Administrator.
2. Write following two commands which will update your registry.

reg add HKLM\Software\WOW6432Node\Microsoft\InetStp /v MajorVersion /t REG_DWORD /d 10 /f

reg add HKLM\Software\Microsoft\InetStp /v MajorVersion /t REG_DWORD /d 10 /f

This should solve your problem. Refer to this link for more details.

Answer 3

Modify was greyed out for me, but adding the IIS Management Console under programs and features fixed this for me. Also on Windows 10 fall update.

Answer 4

Instead of installing the bloated IIS, I get mine resolved by installing Internet Information Services Hostable Web Core from the Windows Features

Answer 5

I got this issue when trying to run a project targeting Framework 4.5 in VS2017. After changing it to Framework 4.6.X it got fixed by itself.
