The issue you're facing seems to be related to file locking and build configurations. To resolve it, try the following steps:
Make sure that all instances of the IDE are closed before attempting to rebuild the solution.
Check if any other processes or services are using the DLL files. Close them if possible to release the file locks.
Verify that your build configurations are set correctly for each project (Release vs. Debug).
Ensure that the relative paths in the project files (.csproj) are correctly referencing the appropriate directories.
Double-check for any circular references or dependency conflicts in your solution and resolve them.
If the problem persists, you might consider cleaning the solution, deleting the bin and obj folders manually, and then rebuilding from scratch. Additionally, you could try using a different build tool or IDE to see if the issue persists across different environments.
