csc.exe | Compiler Failed Error Code [3 Solutions]

A system error code is a number that a Windows program may show in response to a specific problem it is experiencing, often followed by a short error message.

When the CSharp compiler (csc.exe) is unable to access resources and source codes, there may be a permission error on the local framework. To solve the error, you must Right Click on the virtual directory and then select properties. You can then click on “Create” next to the “Application” Label and the textbox. It will automatically create the “application” using the virtual directory’s name. Now the application can be accessed.

Fixes for the Error

There can be several fixes as per OS used. Some of them are mentioned below

Fix 1

The application pool identity from “Local scheme” to “ApplicationPoolIdentity.

Fix 2

  • Delete the following files from the path
  • C:WindowsMicrosoft.NETFrameworkv4.0.30319/Microsoft.NETFrameworkv4.0.30319/Microsoft.NETFrameworkv4.0.30319/M
  • Temporary ASP.NET Files (The latest system version is 4.0.30319.) Choose the most suitable version for your machine).

Fix 3

“An error occurred during the compilation of a resource needed to service this request,” says another error. Error in the Compiler

The compilation failed for one of the following reasons:

There are certain conditions that the compiler is unable to fix. The program creates an object register, but you should not attempt to run it.

An internal compiler table has reached its limit. The program’s execution halts and XL Fortran fails to generate an object register.


There is no such file as an include file. The program’s execution halts and XL Fortran fails to generate an object register.

A program error has been discovered that is unrecoverable. The source file is no longer processed, and XL Fortran does not create an object file. This error is normally corrected by correcting any software errors that were recorded during compilation.

As a result, simply understanding the code will not suffice in understanding how to resolve the problem. You should also be aware of the context in which the machine error code was discovered.

Assume you’ve got Error Code 112, which suggests that there isn’t enough space on your hard drive. Knowing the code is useless unless you also understand where it happened, such as which disc it refers to. Combine the information with what you were doing at the time the mistake happened, such as attempting to add more data to the hard drive. The approach would be much easier to comprehend and implement as a result.

This is an error that the compiler should repair. The software should work properly.

 The message of warning. It does not mean a mistake, but it could indicate an unforeseen situation.

One of the compiler options that checks for conformance to different language levels created a warning message. If you’re worried about portability, it might mean a language feature you should avoid.

This is a message of knowledge. It does not mean an error; rather, it is something to be mindful of to prevent unpredictable actions

  • Compilation failure is suggested by the message levels S and U.
  • The compilation was effective, as indicated by the message levels I, L, W, and E.

If the compiler finds a serious error, it will stop without generating output files by design (severity S). By specifying a different severity with the -quality option, you can make the compiler stop for less serious errors. With -qhalt=e, for example, the compiler will stop if it finds any errors of severity E or higher. This technique will cut down on the amount of time it takes to verify a program’s syntactic and semantic validity. The -flag choice can be used to restrict low-severity messages without stopping the compiler. See the -suppress Option if you only want to prevent unique messages from being sent to the output stream.

How System Errors Are Used

The Windows operating system issues an error code to explain a problem it has with a software application, similar to how a doctor would use a specific word to describe a list of symptoms to a patient. This makes it easier for a software developer to understand what is happening and, therefore, how to fix it.

Operating System

An operating system may be compromised or damaged in a variety of ways, but these problems are relatively uncommon.

The most significant error message in Windows is the Operating System Not Found error message, which means that one cannot even be found

What Does a Machine Error Code Indicate?

As part of the programming interface with the Windows operating system, software programmers are given system error codes. In other words, device error codes are predefined error codes and error messages that software programmers may use to inform you (the software user) that the program is having a problem.

These predefined machine error codes aren’t used by any software program. Some software systems have their own set of error numbers and messages, in which case you can look up the list of error codes and what they mean on their official website or manual.

What Do the Various System Error Codes Indicate?

When you try to save a file in a music editing program, you could get Error Code 206 as an example of a system error code. In this case, the mistake can be avoided by shortening the file’s name before saving it.

This error code most likely indicates that the hard drive is overflowing. This error can be easily resolved by deleting temporary files or freeing up space on other parts of the hard drive.

More on Error Codes in the Operating System

In Windows, the same device error code will appear in hundreds of different locations. As a result, the codes are standardized and they refer to a wide range of situations. Instead of having different Error Code 206s for different file extensions or folder positions, Windows uses the same one in all situations where the file name/extension is too long.

 What Do You Do If You Receive a System Error Code?

What you should do next is essentially decided by the machine error code. The solution to the error in the first example is fairly self-explanatory: change the file’s name because it appears to be too long. But it isn’t always that easy.

Almost every hardware and software manufacturer on the planet offers online technical assistance and information for the goods they sell.

If you want to download drivers from a hardware manufacturer, call them for help, download a manual, or study a problem with their hardware or software, you’ll need to find their technical support information.

As Windows experiences a severe problem, it is forced to “stop” entirely, resulting in a Blue Screen of Death (BSOD).

Any Windows version, including Windows 10, Windows 8, Windows 7, Windows Vista, Linux Mint, and even Windows 98/95, can produce BSOD errors.

Return Code from the Compiler

The following are the compiler return codes and their meanings

There were no errors serious enough to cause the compiler to stop processing a compilation unit.

The compiler encountered a halt severity error of severity E. (whichever is lower). The compiler may have continued processing the compilation units with errors, depending on the degree of halt severity.

A choice error has occurred

  • An error occurred in the configuration file.
  • An out-of-memory mistake has occurred. There isn’t any more memory available for the compiler to use.
  • A signal was obtained with an error. You’ve got an unrecoverable error or an interrupt signal.
  • There was a file not found the mistake.
  • An input/output error has occurred. 
  • The Return Code at Run-Time

The return code to the operating system is 1 if an XLF-compiled program terminates abnormally. This is an update from XL Fortran Version 2, which in this case used a value of 232. The return code is 0 (by default) if the program ends normally, or MOD(digit string,256) if the program ends due to a STOP digit string argument.


Troubleshooting a blue screen error can be difficult because you have no choice but to restart. Thankfully, almost every stop error has a hexadecimal-based stop code that can be used to check for a solution.

The error arises when a user creates some web app by making use of visual studio on his PC. System then creates an automatic virtual directory for him and configures the same as an application. But if a user creates the directory manually and the same is not well configured, browsing and application won’t work. This will show the compiler error on the screen causing a great trouble for the user. Moreover, if you have subdirectories in your application, you must have web configuration file for them. There are some features, which can’t be set in this config. Settings can/t be overridden and the same arises.
