I have created C# console app .Net framework 4.5.2 project which export data from sql server to csv file. Everything works fine from visual studio when I debug the project and also work if I run application.exe file from my PC. But I want to deploy this application on my different server so I copied whole debug folder to server and tried to run exe file but it says program not able to run and close.

What I have tried:

I copied whole project folder also but same result. So I’m confuse what I’m missing.

That is not the correct way to deploy .NET applications. Use the Settings -> Publish tab to do it properly.

We can't tell - there are just too many variables.

But ... the most likely two possibles are that the SQL connection string is wrong, or the output location does not exist / have write permission in the new system.

When you release software, you shouldn't copy the debug folder - create a release build (change "debug" to release on the VS menu bar and rebuild) and release that instead.

Start by adding logging statements to your release code to output to a file and show you how far the app got before failing. Then after is crashes, look at the log and find out what the last log was. Then add more logging code between that and the next log statement iot didn't get to, to "narrow it down". Repeat this including more info of what is going on (variable contents, return values, etc.) until you have a good idea where it's failing - you should be able to work out from there what the problem is, or at least provide code fragments which illustrate the problem.

Sorry, but we can't do any of that for you!

Thanks a lot. It worked after changing to release from debug.
I will start adding log for future error check.
