Failed to copy "obj \ Debug \ {project} .dll" to "bin \ {project} .dll"

Question

Visual Studio Express 2013 for the Internet often throws this error when I try to start my project, and the only permission I found is to stop and restart Visual Studio or (sometimes) completely restart Windows. What could cause something like that?

Answer 1

Create a preliminary assembly in your project by going to the project properties (right-click on the project in the solution explorer and select the "Properties" parameter), select the "Events" tab. Add this code:

if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
