Today I got a strange error.
Error CS0518: Predefined type ‘System.Object’ is not defined or imported
Strangely, all nant related tasks just work as accepted.
After a little googling i’ve found a solution here, that says that i need to reference mscorlib. I did that and the error was gone.
Then I opened my project preferences and saw that a checkbox was check, which told not to reference mscorlib. After unchecking the checkbox, the day was saved.
The screenshot shows preferences in SharpDevelop 3.1
