When I try to build my code in VS 2012 I keep on getting build error; and in the error list it says 0 of 1 error; and no error message is shown there. So basically, I am stuck because I can't find where the error is (if there is actually any). I have tried restarting VS; but no help. The code has been working fine; I only modified the code deleting one of the forms.
Has anybody come across such issue?
Most likely your errors are being filtered so you only see warnings or messages. Here is a link which talks about viewing errors and sorting / filtering them. Make sure you have Errors selected or just view all 3 categories.
