Impressions during developing my first application with Mono and Gtk# (GtkSharp)

2012/09/30 Comments off

Why Mono? Why Gtk?

Over the past couple of years I have been developing C# ASP.NET enterprise applications. So I am quite comfortable with the Microsoft stack.

That answers the first question: Mono gives me C# and the .NET stack.

On the other hand I have been using linux as a desktop environment on my home machine for over a decade. I am comfortable with using linux as my primary OS.

That answers the second question: Mono gives me access to Gtk, the graphics library of gnome, which is the default “desktop” in many linux distributions.

The App

I want to synchronize different Git repositories semi-automatically using a Gui.

  • Default behaviour of the automation can be loaded via a Json file.
  • Each entry describes a repository set to be synchronized.

The app is located at

I also published a small demo application for gtk# and treeview:


Monodevelop vs Visual Studio

I’ll keep it brief: If you’re used to Visual Studio and ReSharper, Monodevelop does not come close. On the other hand Monodevelop is a full C# IDE which works with linux. And Monodevelop can be used cross-plattform.

Gtk# API

The Gtk# API is not your typical .NET library. You will very soon notice that the origins are C/C++. This takes some getting used to if you have a .NET background.

Typically there are no return values. Instead Gtk# methods very often use the “out” keyword in .NET because that comes closer to the C++ implementation using pointers.

Here is an example:

## Mono Gtk# Code
bool someBool = false;
if (listStore.GetIterFirst (out iter)) {
do {
someBool = (bool) listStore.GetValue (iter, 0);
} while (someBool && listStore.IterNext (ref iter));
return someBool;

## Pseudo-C# Code
return listStore.ToList().Any(s => s.MyBoolProp);

From the .NET side, I don’t like the Gtk# API. I prefer methods having return values. I guess it is a matter of tast. If it would really bother me, I would write some wrappers around… 😉

Antivir regression bug makes Visual Studio 2010 unusable

2011/07/09 Comments off

The current version of Antivir Personal slows down Visual Studio 2010 making it unbearable to develop ASP.NET applications.

Debugging with active Antivir: appr. 5min for an empty Default.aspx page to display.

Debugging with deactivated Antivir: a few seconds for an empty Default.aspx page to display.

Until Antivir fixes this bug I will give Microsoft Security Essentials a try.

Regression because this has been addressed and fixed in December 2010:

Visual Studio 2010 comes with its own version of SQL Server Express.

If you try to install SSMS(E) (SQL Server Management Studio Express) afterwards and run into trouble, take a look at this post by Alexander Zeitler.

NHibernate Code Completion (IntelliSense) for Visual Studio

2010/12/08 Comments off

Enable code completion (IntelliSense) in Visual Studio by copying the XSD files from NHibernate to your Visual Studio’s XML folder.

For example (NHibenrate 2.0.1):

Files to copy:



C:\Programme\Microsoft Visual Studio 10.0\Xml\Schemas

Using NUnit with Visual Studio Express

2010/08/20 Comments off

Since Microsoft’s Visual Studio Express edition does not allow installation of any plugins anymore (f.ex. TestDriven.Net), here is a quick workaround to get NUnit-GUI working. Add this to your Post-Build section of your Project settings:

copy /Y “$(ProjectDir)App.config” “$(TargetDir)$(TargetFileName).config”

Problem upgrading VMware Tools (because of JIT-Debugger) solved

2009/05/26 Comments off

After resurrecting an old VMware installation (I started with the first freely available version of VMware.. version 1) and upgrading successfully (see this post), I was not able to update Vmware Tools within my guest OS (Windows XP SP3). I tried the automatic update option as well as the interactive update option. Both resulted in Visual Studio’s JIT (Just-In-Time) Debugger complaining and aborting the upgrade (on the guest OS).

Solution: Within the guest OS (WindowsXP in my case), uninstall VMware Tools and restart the guest OS. After restarting the guest OS the VMware UI “VMware Tools”-section will have changed from “Upgrade VMware Tools” to “Install VMware Tools”. Clicking the latter installed a fresh version of VMware tools without any problems.

This worked with VMware-server-2.0.1-156745 in combination with host OS Ubuntu 9.04 and guest OS Windows XP SP3.
