"The XML page cannot be displayed in ASP. NET2.0. The XML input cannot be viewed using the XSL style sheet ." Problem Solving

After my multi-party queries and observations, the reason why my web serve encountered such a problem
Before. net framework 2.0 is installed with IIS,
Specifically, I first installed iis, followed by. net framework 2.0.
However, after testing, my iis cannot be used. It is said that this is a bug in ms, which has not been fixed for a long time,
As a result, I uninstalled iis and reinstalled it again, so a new problem occurred.
"The XML page cannot be displayed. XML input cannot be viewed using the XSL style sheet. "

After selecting the version of iis in the iis management tool, the following error occurs: "An error occurred while accessing the IIS metadatabase"
The result is that the aspnet account is not registered,
Next, I began to find a solution. I was very sorry to find an ASP NET account registration tool, aspnet_regiis.
The specific steps are as follows:

Open the vs.net command prompt line,
Enter aspnet_regiis-ir-enable
Solved. Enter aspnet_regiis help to query the specific parameters.
