Viewing studio reports in MVC framework.

Ah ok, yes, this is normally done by the default VS template. Thanks for sharing it.

Hi Blaha, vbmark. I'm using the same example (cloned today from GitHub) and it runs perfectly in IISExpress but when using the local IIS instead I get an error in all actions (besides Index):

Server Error in '/NetWebApp' Application.

Could not find file 'C:\WINDOWS\TEMP\jsreport-temp\meta642b8545-b701-4a29-940c-8f2c0a8cdf26'.

Sure enough, C:\Windows\temp\jsreport-temp has no "meta<guid>" files but has several "req<guid>.json" files.
Any ideas on why it doesn't work in IIS? Or this scenario (run as utility) not supported in IIS?

Thanks

We will look into it

[jan_blaha]

Can you try to change the application pool identity to the LocalSystem?

Can you try to kill all node processes from task manager, recycle the app pool and try it again?

[ssarabando]

Yup, that solved the matter (the change of the built-in account; I had no orphan node processes). That'll probably ruffle some feathers with our sysadmins due to security concerns though... let's hope not. :/
Thanks :)

FYI I've finished the documentation, examples and also introduction video for the .NET jsreport sdk.
