"It works as expected" - then this question is not for SO. Have you tried asking on codereview? — Fildor 18 secs ago
if it is working code, it should go to codereview SO. classes like SqlConnection and SqlCommand deal with unmanaged resources, implement IDisposing and should therefore be wrapped in using. The else branch would not compile due to unterminated string literal. For variable declaration we nowadays use the var keyword instead of repeating the class name. — dlatikay 53 secs ago

as I said, you can post your question 1:1 on codereview.stackexchange.com . The way it is written you are asking for improvements of your working code. This is out of scope of stackoverflow, but totally in scope for the codereview subpage — oli_obk - ker 59 secs ago

The nuances of off-topicness are discussed in codereview.meta.stackexchange.com/questions/5777/… . If you change your question to a concrete improvement (like "how can I rewrite this to get rid of fail!"), then it is back in scope of stackoverflow, but in that case you should still create an MCVE that preferably works on play.rust-lang.orgoli_obk - ker just now

Make a small test environment for yourself: two folders, with few files in them that constitute a representative sample of the real set of files. Split up your problem into bits and begin writing the script. Use the environment you set up for testing. If you get stuck, research the problem for a bit, and if you can't figure it out, then post it here and we will help you debug. Once the script works properly, you can post it on Code Review S.E. if you want to, and they will help you optimize and make it adhere to best practices. — stybl 33 secs ago

Q: ASP.NET Users and SignIn managers

TheQultThe is any difference between those implementations? Some are less secure than others ? Default implementation: private ApplicationUserManager _userManager; public ApplicationSignInManager SignInManager { get => _signInManager ?? HttpContext.GetOwinContext().Get<ApplicationSignInManager

 
All I'm saying is that your application has security holes. I could list the problems that I can see in the code you posted, but that won't do you much good, because i have to I can't say exactly which ones without a complete code review, but alone the code quality you show here demonstrates that you (or your company) lack basic security knowledge, so it's almost guaranteed that there are security holes. — RoToRa 7 secs ago

I haven't been working on extraordinarily complex programs though.
 
They make management happy, because management can follow nicely drawn arrows.
 
why would management want to know how the innards of an application work?
 
@Zeta My management doesn't usually care how things work, except the VPBIS, who just wants to know what can fail. Lol
 
or: why would they want to see anything other than a summary of testcases and testcoverage?
