I'm voting to close this question as off-topic because You do not have any problem so your publication is not within the requirements of SO, it even seems to be off-topic since this one of the POB, IMHO is more appropriate to publish it in codereview.stackexchange.comeyllanesc 14 secs ago

@CaptainObvious @MathieuGuindon you're really fast, I tried to VTC and you had already closed it.
 
@pacmaninbw A bored @MathieuGuindon is a quick @MathieuGuindon. Trollface.gif
 
Also it's 10:17 so @MathieuGuindon probably just finished his walk for his first coffee. ;)
 
waiting for work laptop to open up SSMS, VS, Outlook...
 
2:19 PM
Good luck
 
I guess Chrome isn't helping lol
 
I hate Chrome so <> much.
 
ooh, Outlook is up
gotta love booting on a Monday morning
ooh, SSMS is alive
 
You know I stopped using SSMS as much.
 
@MathieuGuindon I use FireFox instead. I remember the days when I would walk into my cube at work, log into my Sparc Station (sun microsystems) and go to the coffee machine because it would take 5 minutes to load my apps.
 
2:22 PM
VS is up!
@pacmaninbw IDK, last 3 times I tried downloading FF it wanted to install a bunch of bloat/crap/-ware "toolbars" and whatnot. gave up on FF right there & then

Is anyone here up to date with the EU machine directive?
@MathieuGuindon Gives time for coffee.
 
What is an EU machine directive?
 
2:26 PM
@MathieuGuindon Oh? Not last couple of times I checked. Using the portable version at work, no bloatware at all.
 
@Mast do you need extra coffee on Monday?
 
Basically, the law on how to build a safe machine.
In the entire European Union.
 
@Mast didn't it used to be hosted on SourceForge? (is SourceForge still a thing?)
if it's no longer there, that might be why it's clean now
 
@MathieuGuindon SourceForge is evil.
And probably. Not anymore.
Lots of OSS used to be hosted there, until they started loading crap with everything.
 
yet FF stayed there until it became unbearable
 
2:29 PM
Nowadays you just go to mozilla.org.
@MathieuGuindon We all make mistakes. Browser companies a bit more than average.
 
@Mast I read a thread about how SourceForge changed literally when another company acquired it.
 
For those really interested in my current gripes with the machine directive, see here.
@410_Gone Wouldn't surprise me. Change of ownership tends to do odd things to policy.
 
@MathieuGuindon mozilla.org has been the preferred site for at least 5 years.
 
@pacmaninbw I mean Mat is pretty old so....
Wait I said the quiet part out-loud again
 
@410_Gone I think I'm a lot older.

@MathieuGuindon AFAIK it is still a "thing"
 
@MathieuGuindon I'm right there with you, chief.

This is not Code Review, but ... what purpose do these classes have? Anyway, as the error states, the member declared as DbParameterCollection doesn't have an AddWithValue() method, which you shouldn't use anyway. It won't work with non-mock classes either. Just use Add(new XxxParameter(...)). — CodeCaster just now

So thank you for screaming at them.

@Vogel612 I can't tell if that's good or bad, but I wish her luck with whichever outcome she is hoping for.
