Unable to copy a file from obj\Debug to bin\Debug

Question

I have a project in C# and I get this error every time I try to compile the project:

(Unable to copy file \"obj\\Debug\\Project1.exe\" to \"bin\\Debug

Answer 1

Before rebuild the solution, clear the project, stop the IIS and open the "bin" folder property. Uncheck the Read-only Attribute in general tab then rebuild.

Answer 2

I had to go into windows explorer and delete the bin/debug folder as well as the obj/debug folders. Then I cleaned & rebuilt the project.

Answer 3

Rename the assembly to a different name to solve this issue.

Answer 4

Disable any Anti Ransomware (like MalwareBytes) running, then the problem should be solved.

Answer 5

Well i have the same problem, my way to fix it was to stop and disable the "application experience" service in Windows.

Answer 6

Solution1:

1. Close the project.
2. Delete the bin folder.
3. Open the project.
4. Build the project.

Solution2:

Add the following code in pre-build event:

attrib -r $(OutDir)*..\* /s

This command line code will remove the ready-only attribute of "bin" folder. Now visual studio can easily delete and copy new dlls.
