So you're still getting this error message?

'IServiceProvider' does not contain a definition for 'GetRequiredService' and no accessible extension method 'GetRequiredService' accepting a first argument of type 'IServiceProvider' could be found (are you missing a using directive or an assembly reference?)

Here's a patch of what changed to add INavigationProvider to a control inside DNN:

Hi Brian,

yes, I am still on this error. The only difference I see is here:

   this._navigationManager = this.DependencyProvider.GetRequiredService();

In my code it reads as

   _navigationManager = DependencyProvider.GetRequiredService();

Thanks for your patience.

Happy DNNing!
Michael

Can you show me your project file (or just the references from that file)?

Hi Brian,

two are custom stuff, but here are the other references ({ = <, } = >):

Solved...

A reference to Microsoft.Extensions.DependencyInjection.Abstractions was required...

Thanks, Brian, for your help!

Happy DNNing!

Hi Michael/Brian
Sadly [for me] I'm an occasional Basic Code producer of DNN Modules.
I have a a couple of modules that have worked fine for four years... until I 'upgraded' to DNN 9.5.0 which appears [I think] to be broken in that calls to NavigateURL is generating very odd behavior.

I have a Development machine that, after compilation, works fine.

On the Operational machine, It seems that the Request.Params being passed to an editing sub-form have 'moved up one' in that Params((3) is now Params(4). As a result, I get errors across the piece.

I've read the dialog between Brian and Michael... didn't really understand much of that  but if you could point me at a basic code example of how the new NavigateURL mechanism is implemented, that would be great.

... Still not at all sure why it works in one machine and not the other... the /bin DlLLs are all precisely the same, so I suspect some Microsoft based software is at fault. Any ideas?

Regards and in some desparation,
Duncan

In Visual Basic.NET, the base of indexers can be set to 0 (the default) or 1 (see Option Base statement docs). So it's possible that something in your toolchain is changing the base, which would result in this kind of error. I don't think it would have anything to do with the new INavigationManager.

update:
I've been chasing a ghost.

Because I use Request.Params to pass a number of parameters to sub-dialogs, [which has always worked...].
And when I updated to 9.5.0 I casually added a local language [English:UK] to the site... DotNetNuke added that to each parameter set ! :)

... A lesson learned.

However, I'd still like to see a Basic Code example of the update to NavigateUrl() function as that will be removed in version 11.0

regards,
Duncan

Here is a full synopsis of how to move from the old NavigateURL to the new method

References for your project must be made to:

• DotNetNuke.Abstractions
• Microsoft.Extensions.DependencyInjection
• Microsoft.Extensions.DependencyInjection.Abstractions
• * the dlls can be found in the bin directory
   
• DotNetNuke.Abstractions is required for INavigationManager and must be declared above as an imports or using (depending on language) before your class definition
• Microsoft.Extensions.DependencyInjection is required as an imports/using so that you can call on the PortalModuleBase.DependencyProvider

Each of these returns a string which you can then do redirects with or whatever.

• The old way - Common.Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "YourControlKey", "mid=" & CStr(ModuleId))
• The new way - DependencyProvider.GetRequiredService(Of INavigationManager).NavigateURL(PortalSettings.ActiveTab.TabID, "YourControlKey", "mid=" & CStr(ModuleId))

If you want to circumvent the call to DotNetNuke.Abstractions you can call it like this:
DependencyProvider.GetRequiredService(Of Abstractions.INavigationManager).NavigateURL(PortalSettings.ActiveTab.TabID, "YourControlKey", "mid=" & CStr(ModuleId))

Now if someone could please explain why the dev team decided to add all the extra layers to obtain the same functionality??

Three more dlls, two more using/import statements and a longer, more complex line that no longer works on the front page of a module control.
