Hi,

I am having problem with compiling the DLL. Here is the scenario:

Let's say I have created a DLL and App1 is using it. the application will monitor a folder for several hours. The dll and the app1.exe is copied to C:\foder1 directory. The application is running without any problem.

Let's say I need to make changes to that DLL. If I open the DLL project in my Visual studio and compile it, it says that the file is currently used. DLL project is stored in different path. let's say in D: drive.

Why it says the dll is used? The app1 should use the DLL in C:\folder1.

How to avoid this problem?

Thanks
