IIS

We can deploy the project from inside visual studio to IIS or we can deploy it from the IIS server manually.

Below is the screenshot changing that we can deploy  the application on IIS rather on ASP.Net development server directly from the visual studio environment.

The application name and the name of virtual directory need not need to be same

Getting to IIS below are two methods

2nd method is from run type : inetmgr

Creating  virtual directory and viewing it and checking it in IIS

Creating application directly from IIS

All the application can be present in the same application pool or  they might be distributed across multiple application pool  as per the requirement.

When we run a webapplication its going to run inside a asp.net worker process wewp.exe  ever application pool has got its own worker process  if we don’t have application pool all site wll run under same workerprocess and it will be security issue if something happens to workerprocess all the sites will be affected.
