SYMPTOMS

In Microsoft Visual Studio .NET 2002, when you rebuild a solution you may receive the following error message:

Could not delete file File Name. Make sure that the file is not open by another process and is not write-protected.

Note In this error message, File Name is a placeholder for the path and the name of a .dll file.

When this problem occurs, you must restart Visual Studio .NET before you can rebuild your solution.

CAUSE

This problem occurs if the Read-only property of a .dll file from an earlier build is set to true. The read-only property of a .dll file is set to true when the GetAssemblyName method is called to get the name of an assembly.
