no, it wasn't - mostly because of political bullcrap coming from the "I'm purer than thou" crowd. obviously, the biased perception that gnome was using C# exclusively was also due to the same crowd.
this also led to the C#/mono platform lagging behind, so that these days writing gnome apps in C# means using deprecated libraries, which is unfortunate.
