It was recommended I use msxsl.exe to conditionally compile a vb.net project based on a variable defined in a batch file. I did this and it worked twice. The third time though, msxsl.exe had disappeared. I searched my entire hard drive for it but couldn't find it (I have explorer set to show hidden files). I was advised to reinstall .net framework so I installed the 4.81 developer edition. But it did not install msxsl.exe. Can someone please tell me where msxsl.exe went and how I can reinstall it?

2023-02-19T13:13:15.7166667+00:00 Thanks for your speedy response to my question. Msxsl.exe disappeared from my computer after learning to use it and using it successfully a couple of times. It seems like the system removed the file without asking or warning me. I really object to this type of behavior which, in this case, caused me to waste 4 hours of my time figuring out what went wrong. There should have been a popup or warning that the file was being removed from my computer.

2023-02-19T14:08:00.85+00:00 Are you sure that it has not been deleted by Windows Defender, thinking it was a virus ?

2023-02-20T03:01:33.8833333+00:00 Thanks Jiachen Li. Following your link, it looks like Win8 was the last supported Windows version. I'm on Win10 so I don't know how msxsl.exe got on my system. But it was active in my Visual Studio Community installation. I'd still like to understand why it disappeared AFTER I used it a couple of times. Would defender have removed it for some reason?

2023-02-20T20:43:58.1933333+00:00 Thanks for that. The remaining question is: Would Defender or some other part of the Windows OS have removed it for some reason?
