Hi all,

on my developer machine everything works fine.

So I tried to publish a wisej user desktop app to a IIS-Webserver 10.0 (Windows Server 2016) via WebDeploy.

When I call the start-url (e.g. localhost) I receive a "HTTP-Error 500.19 Internal Server Error" with ErrorCode=0x80070021.
The error-message says that a configuration section in web.config can not be used: <add name="wisej" verb="*"...>

That's my web.config file:

Any ideas?

Best,

Harald

okay ... now I'm 1 step ahead ... I changed the following lines in applicationHost.config:

<- from "Deny" to "Allow"

<- from "Deny" to "Allow"

The result is that "default.html" is shown, but the wisej.wx script does not start the application ... what's wrong now?

success ... I found the solution for me:

A useful thing to know is that even if IIS is enabled on a Windows 2016 server machine, Application Development / Asp.Net still needs to be enabled in Server Manager.

I had to install 2 Features:

• .NET Framework 4.6/ASP.NET 4.6
• WCF-Services/HTTP-Activation

After that the following "Roles and Features" are in the installed features list:

Web Server (IIS)
Web Server
Application Development
ASP.net 4.6
ISAPI Extension
ISAPI Filters
.Net Extensibility 4.6

You probably need to enable WebSocket too. It’s not enabled by default.
