After installing ASP.NET 4 I then installed the latest version of DNP with .NET 4 support but going in to configure servers it shows the following 

ASP.NET 4.0:  Not Installed 
ASP.NET 4.0 64-bit:  Not Installed 

Hello,

can you edit your websites after installing .NET 4.0 RTM and latest DNP update?

EDIT: Simple yes/no will be enough :)

If you'll try to add new IIS7 provider you will see that asp.net 4 path will be found. If you want you can add this two records:

ServiceID    aspnet40x64path    C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll
ServiceID    aspnet40path    C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll

to ServiceProperties table in DNP Enterprise DB (ServiceID must be equal to your Web IIS7 provider ID). Even after adding those entries to DB I still cant edit my existing websites. I'm getting this error when I'm entering website settings:

w3wp.exe Error: 0 : [4/14/2010 9:18:30 PM] ERROR: 'Internet Information Services 7.0' GetSite
System.NullReferenceException: Object reference not set to an instance of an object.

   at DotNetPanel.Providers.Web.IIs70.GetSite(String siteId)
   at DotNetPanel.Server.WebServer.GetSite(String siteId)

EDIT2: There is another thing which DNP users should be aware of. Latest DNP update is supporting DNP RC and not RTM ("Added: ASP.NET 4.0 RC support") and when new IIS provider is being added to DNP there are entries with RC build number added to ServiceProperties table (if I r emember correctly it is 4.0.30128 instead of 4.0.30319).

EDIT3: After adding two entries to  ServiceProperties table new websites are being created correctly with five Application poos (1.1,2.0 Classic and Integrated, 4.0 Classic and Integrated) but I still can't enter website settings in DNP Portal.

Its not working with the same error:

 ERROR: 'Internet Information Services 7.0' GetSite
System.NullReferenceException: Object reference not set to an instance of an object.

So well done DNP, you manage to release support for ASP.net 4 RC when the RTM version was released two days ago, and manage to break the IIS 7 provider in DNP. Do you actually test any of your upgrades?

I have been a supporter of DNP since the beggining, but I am seriously giving serious consideration in moving to another platform as the releases are getting weaker and weaker. Whats going on DNP?

 *edit* just rolled back dnp server to 2.12 on the server I upgraded. Backup of 2.12 should be in C:\Program Files (x86)\DotNetPanel Software\DotNetPanel Configuration Studio\Backup\ or similar depending on where you have the installer installed.

Yes

wiredeyes:

Yes

so basically you are sayign that .NET 4.0 under latest DNP is working for you right? IIS6/IIS7?

Sorry. I forgot that you have started this topic :). But have you maybe used my instructions and added proper entries to ServiceProperties table?

There is another thing which people should remember. Under IIS7 (I don't remember how it was under IIS6)  you must go to ISAPI and CGI Restrictions and allow ASP.NET 4.0 extensions

 Any luck figuring out the cause of the error? None here. Installed a copy on a fresh VM and its still not working. You using 2008 or 2008 R2?

if you have test VM then maybe you could try it with .NET 4 RC version to make sure if it works with it. After all there is clear info that RC support has been added.

EDIT: I'm using 2008 R2 x64 with 32bit app pools.

 Same platform as me, if we dont have any news from the DNP team i'll try RC and a windows 2008 32 bit install to see if its a platform issue. Right now I need sleep :P

Yep. Me too. Its almost midnight here (Poland). I'm sure that tomorrow DNP devs will figoure out what is causing this error.

I am running this on a IIS7 Server 2008 R2 64bit, it is a remote server not local to enterprise install in case that has any bearing.

No I haven't bothered to add the DB entries I think I would rather wait for the guys to comment on what should be done first rather than go hacking the DB.

Thanks for the tip for enabling the isapi restrictions, I hadn't done that but it hasn't made any difference to DNP.

Hi All,

Appreciate if you provide as much details as possible so we will be able to indentify the issue(s). Are there any error messages in DotNetPanel Windows Event/Windows Event logs? Any other clues that help to get the puzzle solved are highly appreciated.

Thanks.

The error I gave above was from the DNP error log, it again was(not passing the siteid?):

have you tried RC version? Maybe this is not related to ASP.NET 4 at all but with "Added: ColdFusion 9.x support"

 I've not had time to investigate this yet, but I have the same problem as well:-

ASP.NET 4.0:	Not Installed
ASP.NET 4.0 64-bit:	Not Installed

 Looks like for whatever reason that DNP can not see ASP.NET 4.0

Try to add new web provider and you will see that this two lines will contain (almost - differences are in build number between RC and RTM) proper path to ASP.NET 4 dlls. Of course this should be discovered for already added web providers but for sure this is not the problem here.
