Fixing ASP.NET debug error 0x8013134b
I got the following error debugging an ASP.NET project earlier today:
Auto-attach to process ' w3wp.exe' on machine '...' failed. Error code 0x8013134b.
The problem was that I had installed .NET 2.0 which had registered ASP.NET 2.0 on the Web Site I was trying to debug.
Fixing it is simple:
- Run the IIS Manager
- Right click on the web site with the problem
- Click the ASP.NET tab
- Change the ASP.NET version from 2.something to 1.something in the combo and debugging works again
