- Filename: csc.exe
- Program: Microsoft .NET framework or Microsoft Visual Studio (version 2005)
- Developer: Microsoft Corporation
- Description: Visual C# Command Line Compiler
- File location: C:\Windows\Microsoft.NET\Framework\\csc.exe
- Operating System: Windows 8.1/8/7/Vista/XP and other previous Windows systems
Csc.exe is an executable file that is a component of either the Microsoft .NET framework or Microsoft Visual Studio (version 2005). If you’re wondering whether it is malicious, csc.exe is actually a legitimate Microsoft software and it comes pre-installed on many Windows computers.
CsC stands for Visual C# (C-sharp) Command-Line Compiler, and the csc.exe process helps developers or programmers gather information on the device being used. It does not have a standalone app and you won’t see it listed under the programs list on your PC or the Windows Start menu. It does not have any visible window. The only indication that it is working in the background is when you see it running under Task Manager > Processes.
Reasons Why You’re Getting theCsC.exe Application Error
Here are some of the csc.exe error messages that you might encounter:
- Unhandled Exception!
Application will be terminated.
Do you want to send bug report with Crash Memory Dump to development team?
- csc.exe has stopped working

- csc.exe – Application Error

Since we know that csc.exe is associated with the two Windows components mentioned above, it is safe to assume that the majority of the csc.exe errors that appear have something to do with either Microsoft NET framework or Microsoft Visual Studio. It is possible that the program is outdated, which happens a lot when you just installed a major system update. This means that your csc.exe file was not updated, which prevents it from working smoothly with the latest OS.
System file corruption is another issue you have to look into. When the system files related to the programs are damaged or corrupted, they won’t be able to function efficiently and trigger the csc.exe application error instead. CsC.exe errors that are caused by temporary glitches are much easier to resolve because you only need to restart your computer to make it go away. But if the file corruption was caused by malware, then you need to clean up your computer first before troubleshooting this error.
If you encountered the CsC.exe application error when opening a program on your PC, you should consider compatibility issues between the CsC.exe file and the app you are trying to open. Update the app if necessary and clear its cache before launching it again. You can use a PC cleaner to delete not only your app’s cached data, but other old caches that are stuck on your computer.
