Microsoft Visual Studio 2013 - There were compilation errors. Do you want to continue and run the last successful compilation?

Question

Guys, here’s the deal: I’m developing a program Windows Form for desktop in the C# using the Visual Studio 2013.

However, sometimes when I click on iniciar/ start some project compilation errors appear and I haven’t given a build and even if I did, the warning message would appear again.

Every time that happens, I have to close Visual Studio and open it again. It bothers me a lot because you go programming just thinking the same thing is going to happen.

These are the mistakes I copied when this happens:

How can I fix this mistake?

Answer 1

Some program is ultilizing the compiled file (.exe), or the program itself is running. Maybe by closing the program window by clicking on X, do not finish the process, just close the window. You can use the task manager to view the running processes, or close them. Or it can be an antivirus blocking the file or folder.

Answer 2

For various actions Visual Studio needs privileges of an administration account on the machine.

To run it as Administrator it is necessary that the logged-in user has such privileges (it is included in the local Administrator gurpo of the machine).

Just locate the Visual Studio shortcut, right-click and select Run option como ou Administrador or Run as admninistrator, depending on the language of your operating system.
