monodevelop ubuntu c# appindicator

Question

I am just starting out with Mono-GTK app development. I wanted to setup a appindicator icon in systray. But C# returns namespace is missing.

code: using AppIndicator;

returns error: The type of namespace name 'AppIndicator' could not be found.Are you missing directive or an assembly reference?

What to do?

Answer 1

You need to do the following:

1. sudo apt-get install libappindicator0.1-cil-dev

2. Then add a reference to the library (see image below)

3. Finally, include a reference to namespaces you need. Typically these will be the following:

   using AppIndicator;

   using Gtk;

   using System;

.

Answer 2

Install dependencies:

sudo apt-get install libappindicator0.1-cil-dev

And then compile with

dmcs -pkg:gtk-sharp-2.0,appindicator-sharp-0.1 file.cs
