I gave a talk at NAVUG Summit 2015 about .NET interoperability, here are the slides:
ITD03 Extending Dynamics NAV using .NET framework interoperability
Its all about how to use .NET variables in NAV with different examples.

A quick way to get async/await for WCF calls in Xamarin
Just a quick a way to consume WCF services with async/await:
Step 1.
Generate the proxy code with SLSVCUTIL.EXE, there are plenty of examples for that “out there” 🙂
Find your client class and the interface – In this example they are called ProxyClient and Proxy (interface) and the method we are wrapping is called “Call” thant takes a string parameter and returns a string.
Step 2.
Create a small wrapper method, example:
public async Task CallService(string Parameter)
{
ProxyClient client = new ProxyClient(new BasicHttpBiding(), new EndpointAddress("http://host/service"));
var t = Task.Factory.FromAsync(
((Proxy)client.InnerChannel).BeginCall,
((Proxy)client.InnerChannel).EndCall,
Parameter,null);
return await t;
}
Step 3.
Call the method:
result = await CallService("test");
Thats the shortest version I can come up for solving the missing async/await support for WCF services. You should remove the ProxyClient construction to somewhere else depending on your WCF consumption to reuse the client.
Wysiwyg Editing Control for Dynamics NAV 2013 and 2015
In Dynamics NAV 2013 R2 and 2015 there is a new format for control add-ins. This control add-in is actually done in HTML/Javascript so it will work in both clients.
When running in the Role Tailored Client, a WebBrowser Controls is created for the control, one of the main challenges, is that the WebBrowser Control insist on being a Internet Explorer 7 browser, witch reduces the level of JavaScript that can be used and excludes all HTML5 based controls.
The control here, is a modified version of the Tiny Editor presented here:
http://www.scriptiny.com/2010/02/javascript-wysiwyg-editor/
Download the ZIP here:
Inside the ZIP file you wil find:
EriksTinyEditorControl.zip (ZIP file to import into the Control Add-ins page.
TinyEditor_NAV.DLL (DLL file that need to be placed in the Addins folder, both in the client and on the server).
HTML Editor 2013R2 Demo.fob – A couple of demo objects to show the functionality
This is how it looks in the Role Tailored Client:
Install the interface in the addins folder
Unzip the TinyEditor_NAV.DLL into the Addins folder in the service tier, and on the development client (Not nessesary in 2015)
Register the controll add-in
You need to register the ZIP file in the control add-ins register, if you fail to do this, you will get an error looking like this when starting a page with the control add-in.
Open page 9820 or search for control. It will looks like this, with a list over the controls you currently have installed in the database.
Create a new, give it EriksTinyEditorControl as name and c87fd1af2bffc7dc as public token.
After creating the line, you must import the ZIP file – press import and select the EriksTinyEditorControl.zip file.
Now your database is ready to use the control add in.
Use the control in a Page
Create a simple field in a page, and select the control in the properties (In the ControlAddIn property)
Give the field a name (“Editor”)
To load a value into the editor, use the CurrPage.Editor.LoadHtml(Txt) method.
To get the value back from the editor is a bit more complicated since a javascript control is controlled asynchronous, so you must use the CurrPage.Editor.RequestSave() method, and the use the Editor::SaveCompleted(HTML : Text) event. In the example objects, the “Save button will trigger the Editor::SaveCompleted event.
