- You sure you set correct .NET framework version in IIS?
- You sure that web service is working perfectly fine in your dev environment in Visual Studio?

- >.net framework version is set correctly in IIS .
- > in visual studio itself ,still developing, when I created a sample web servie and pressed F5, this error is coming. I dint deploy it any where.

If you see 500 internal error in VS, you should be able to debug and see it. Using VS internal webserver? What version of VS & .NET?
Sounds like you are doing something wrong at basic level and should be easy to troubleshoot for you and resolve.

Hi, Thanks ..
It was an error from setting in IIS and .net version.
I have corrected it now.

The error was coming because of some services in IIS. I have changed settings in IIS and again registered the .Net version with aspnet_iisreg -i command.

Its working fine now..

What exactly fixed it? What was the setting in IIS? Please share.

I checked the event logs and error was regarding W3SVC service and I checked in net about that and did some changes. I was in a hurry so I dint make a note of what are all changes I did. Sorry for that..

but at the end I found that .net version is not registerd so I used that commad to register asp.net version
