WCF, .NET 4.0, Server 2008 R2 Installation Problems
I've had quite a time installing WCF .NET 4.0 on Server 2008 R2 this evening. Here's some things I ran into, hopefully they'll help!
1. - AppPool has to be set to 4.0. This is a no brainer, but one I forgot.
2. - 'C:\Windows\Microsoft.NET\Framework64\v4.0.30128\Temporary ASP.NET Files' - Needs to have app's user set to be able to write (Change version to version of 4.0 you use)
3. - I installed IIS in some funky manner apparently! I kept getting "Bad module "ManagedPipelineHandler" in its module list" errors on all my apps. Re-running C:\Windows\Microsoft.NET\Framework64\v4.0.30128\aspnet_regiis.exe -i got me where I needed to go. Again, replace the version with your v4 version.
4. - Another obvious but tricky one. I was getting 404.0 errors on ALL asp.net pages, but not static files. Remember to give both your app user and IIS_IUSRS access to your files!
