<t>Hi George,<br/> <br/> The error message (which starts with "VN") when compiling from XIDE means that it comes from the vulcan compiler, not the X# one. I think you are using a normal app for testing, not a standalone .prg file, is that correct? In this case, you need to open the app properties an...

<t>Hi George,<br/> <br/> Thanks for your report. I confirm that System.Drawing.dll is not automatically added as a reference, but even so, for some reason in my machine the WinForms app template builds and runs just fine here! Not sure why this is happening, will investigate it. I guess if you manua...

That should read "the X# compiler" of course!!

<t>Hi George!<br/> <br/> The current version of the C# compiler does not support USUALs anyway, so your sample is producing an error at this line with a message "Type expected". In future builds, there will be a compiler option with which you'll be able to specify that you want to use the core versi...

<r>Hi Wolfgang,<br/> <br/> Actually the X# compiler found this exact problem also in my old VIDE code, about a dozen times! In all cases it was of course bugs in my code that were not caught by the vulcan compiler earlier and were causing incorrect runtime behavior, was embarrassing to realize this ...

Karl,

I don't think it should be made different in X#, either. This is the syntax with which it was introduced in c#, so we need to follow it as well.

But why MS designed it this way, is still a mystery to me..

Chris

Karl,

Exactly my thoughts as well
