Tips and Tricks in a world of Mix

OS: Windows 7 x64 bit

IIS : 7.5

You are opening your web site and there it is :

Untitled

It’s coming with enigmatic messages like this :

Untitled1

So , if take a closer look , the only world that matters here is the “MIME” – that means that some handler of the pages you want to show is not installed properly on your IIS.

I was only trying to show

.aspx pages but with no luck, even though in the Handler Mapping in the IIS it’s been shown

I knew that the file that installs the extensions is called aspnet_regiis.exe .

After a quick search I’ve found a few of those.

So you can go to the Framework folder and find the files.

Pay attention that one is for Framework v4 and another for Framework v2.

So actually I had the handlers for the wrong Framework. My Website is Framework 3.5 , that means extension of Framework v2 are needed.

Run –> Cmd –>

Untitled2

And now you can watch your handlers again :

It has added the Framework v2 extension for .aspx pages as well.

(Interesting thing to see , that hence my OS is 64 bit it’s automatically installs support handlers for 32 bit OS as well ).

That’s it , now you can see your .aspx pages.

    Thanks a million for your help! I couldn’t see my aspx pages via IIS 8.0 on my Windows 8 Pro machine (was trying out Umbraco 6.06). I tried so many solutions like adding the .aspx as a MIME Types as text/html or even application/aspx but neither worked.

    When I went to Handler Mappings, I noticed I did not have the entries for the 4.0 versions (neither 32- nor 64-bits) so I tried to install .NET 4 via command.

    When I tried to install the .NET Framework 4 via command prompt, I got a message that it should be installed using the DCIM command, but I knew that I had previously used that command to install it! So I went to “Turn Windows Feature On and Off” and discovered that some sub-features were disabled. I enabled them all, restarted my PC, and voila! I can now correctly view my aspx pages!

    Thank you once again for your guide here; it pointed me to what I was lacking in my settings! Thank you!
