Fellow .NET Users,

First off, we're using Microsoft Teams to host our meeting this month. You can join by clicking here.

As we enter our 6th month of doing our meetings virtually I'm still impressed at how well this community comes together despite all of the limitations on our ability to be physically near one another. We have a great time between meetings interacting with each other on our Slack Workspace and there is always a good amount of participation in the meetings themselves. Earlier this month we held another game night where we played a collaborative game and laughed with one another. It was a truly good time!

For this month's meeting, I had a speaker lined up, but sadly, this individual had a family emergency come up that prevented them from being able to speak. With no speaker, I wasn't sure what the next meeting was going to look like. I reached out to the group and quickly found numerous people who wanted to help with our lightning round sessions. Thank you so much for the many strong supporters of our community. We're back on track and ready to go!

Join us on Thursday, September 24th at 6:00 for our next virtual .NET User's Group meeting. This month we're going to try something new by using Microsoft Teams to manage the presentation. Our goal, as always, is to raise the level of interaction among our members and we hope that Teams will help us do that. You'll be able to more easily interact with our speakers by using this format. Details about how to connect to the session will be made available closer to the time of the event. Our sponsor for this event, DTN, will be giving away two $50 gift cards. Please join us for an opportunity to win!

A simple pattern for adding SQL Injection detection to all your .Net Code by Rob Kraft

Organizing Your Code Projects by Marcus Kern

Using Virtual Hard drives to Keep track of all your ideas, files and source code on your local computer.

On Windows 10 and windows in general keeping track of the many personal, company and side projects can be a daily task in of itself not to mention the deep deep depths of required files and folders just to add dependancies to your projects and Ideas. Ever wish you could have a dedicated Hard disk for your projects? Have you ever tried the "Hot Swappable" hard disk mount only to find out that you couldn't hot swap the drive within a Windows Workstation environment? How many 2.5 or heaven forbid 3.5 drives do you have laying around gathering dust that say something to the effect of 2006 - Home Project and you're afraid to mount it as to find the black hole of side projects that was your greatest ideas from the 00 era?

Well I believe I found a method of organization for your personal, company and side projects that not only allows you to be the data hoarder you are. But to organize projects in such a way that you can have the ease and convinence of a root drive dedicated to one project while having the ability to "No Muss, No Fuss" organize your projects in a file driven way.

Come and see as I'll show you how to organize using virtual hard disk as well as Virtual Hard Disk "Inception" the Feng Shui art of organizing.

For more advanced topics (Not to be presented in this lightening talk) include Bit Locker my personal project drives, Just like (kinda like) One Drive Personal Vault Folders, I'll be including my github repo that provides Task Scheduler Scripts and additional concepts like moving Windows Store Apps to a dedicated Virtual Hard drive (For those that can be moved), AND Profile Management: Symbolic Links make my computer {Faster|Slower|Smarter} You decide. :)
