Enable / Install .net 4.5 on IIS?

Question

I'm pretty new to using C# and IIS and have been having a hard time getting my .net updated to 4.5. My application as of right now is just a single handler page with no solution hosted on a url controlled by Iis. The current version my IIS is running for that application pool is v4.0 . I want to enable v4.5 but don't know where to start. I've been searching google for the past few hours now but none of it makes any sense to me.

Answer 1

.Net 4.5 still uses the 4.0 CLR and that's what you're picking. You won't see an option for 4.5 here. Just ensure whatever version you want is installed and compile your application against the newer .Net versions (which go up to 4.6.2 right now) and it will be just fine.

Note: you can use any .Net 45 application with v4.0 app pool
