Question

I try to start ilasm from C# using class ProcessInfo

 string arguments = string.Format("\"{0}\" /exe /output:\"{1}\"  /debug=IMPL", ilFullFileName, exeFileFullName);
 ProcessStartInfo processStartInfo = new ProcessStartInfo(CILCompiler, arguments);
 processStartInfo.UseShellExecute = false;
 processStartInfo.CreateNoWindow = false;
 processStartInfo.WorkingDirectory = @"c:\Windows\Microsoft.NET\Framework\v4.0.30319\";
 using (Process process = Process.Start(processStartInfo))
 {
    process.WaitForExit();
 }

the arguments are:

"path_to_il.il" /exe /output:"path_to_exe.exe"  /debug=IMPL

and then it gives me the error:

The application was unable to start correctly (0xc0000007b). Click Ok to close the application.

The odd part of that is, when I do exactly the same actions manually using bat file

"c:\Windows\Microsoft.NET\Framework\v4.0.30319\ilasm.exe"  "path_to_il.il" /exe /output:"path_to_exe.exe"  /debug=IMPL
pause

it does work.

What did I miss?

I think you need to set the file name as well:

        processStartInfo.FileName = "ilasm.exe";
