Hi, I'm currently using SolidWorks with Wine 1.3-2, and it works pretty well now. Unfortunately, some add-ons depends on .net30, and particularly WPF. As mono2.x doesn't support WPF, is there a way to use native one from .net30 ? I tried to install dotnet20 and 30 only with winetricks, but it doesn't helps. In fact it trashes my SolidWorks installation, and i had to restore my wineprefix to be able to use it again. When installing mono2.6 alone, Solidworks complains about WPF missing. So : 1 - Does it makes sense to install dotnet30 for another purpose than making installers happy ? 2 - does installing dotnet30 with mono 2.6 makes sense in this case ? 3 - is there a way to prevent it from making SolidWorks unuseable ? Thanks for any help, Denis
