I’m running IIS 7.0 on Windows Server 2008. It previously had .NET 4.0 installed with Application Pools for ASP.NET v4.0 and ASP.NET v4.0 Classic.
I’ve now installed .NET 4.5 (v4.0.30319) and I know that .NET 4.5 is an “in place upgrade”, but do I need to re-register .NET 4.0 with IIS?
e.g. C:\Windows\Microsoft.NET\Framework\v4.0.30319>aspnet_regiis.exe -ir
No, you don’t need to re-register. I recently installed .NET 4.5 and did not change any IIS settings.
