Has the development of classic ASP been stopped at Microsoft side and if yes, when?

Dear Microsoft team,

we have an application, which was developed with classic ASP. We have found the information, that ASP.NET is the successor of classic ASP.
The question is, has the development of classic ASP been stopped at Microsoft side and if yes, when? Or is classic ASP still a part of ASP.NET?

Thank you!

Kind regards
Yauheniya Seliazniova

See Classic ASP Not Installed by Default on IIS 7.0 and above. ASP is not a part of ASP.NET, they both are parts of IIS.

And do not confuse development with support. Microsoft still supports ASP.

There isn't any development (but bug fixes) on classic ASP at Microsoft since 2002, in which year ASP.NET was officially released.

You can still host classic ASP web apps (alone or with ASP.NET) on IIS, as Microsoft supports that for all Windows releases at this moment. But keep in mind such legacy technologies are risky in various ways.

thank you for the response.
Which risks do you see for such legacy technologies?

  1. Windows hotfixes might break classic ASP unintentionally. Happened several times in the past when VB script engine was patched for security. 2. You cannot embrace new things in your web app as classic ASP does not have the necessary building blocks (like gRPC and others). If you just maintain the current functionality of that legacy web app, then the risks can be under control.
