This is my first time using S#arp Architecture 2.0 in a project.
There is two folders in tasks project : Commands and CommandHandlers.
I shearch about it and tried to undestand by the cookbook project what do i have to put there. I am imagining that i have to do something like it was before: a "viewToModel" function and a SaveOrUpdate in the IRepository.
Somebody can explain the "Commands and CommandHandlers" or/and give me a good documentation about it?
Thanks a lot!
Have you seen the Cookbook wiki? Using commands?
From your questions, I understand you are after some sort of CRUD functionality, in which case going for a command and handler approach might be overkill, just load the entity in your controller, copy values from the form and save it. Using commands is more suited for a Task based UI and where there is some behavior you want on the entities.

As title suggests, I am creating open source project that is in .net core 2.0. here is the architecture of it.
Now, it's working fine with everything including code first, seeders, swagger UI, TDD etc.
But there are many places where I have to add/modify classes when I want to add new Table in Database (see SimpleCRUD.Model > Entities)
So, I think I can reduce that boilerplate code, but I am not sure what is best way to do it.
What I did so far?
I tried to create a windows app, which will check and generate code for new added entity.
What I am trying to achieve?
Is there anyway I can add some kind of code in my current project and that will check after each build? is it feasible? any other suggestion to make it working perfectly?
Reference
I have checked this working in few other frameworks like serenity, asp.net boilerplate etc.
T4 temples can help cut down the boiler plate...

You've asked for my help here
I agree with other posters that you might want to look into T4. It sounds like you also want to create an MSBuild task.
I outlined the steps to do this for a different question in post here
You can find my code generators under this folder, CodeGen.SessionProxies
The t4 example can be found here: AppSessionPartials.tt
The MSBuild task can be found here: GenerateSessionProxies.cs
I had it generating a nuget file through the CodeGen.SessionProxies.nuspec. You won't find it on nuget.com; I had a local nuget repository. It would be helpful to you to look at the corresponding install.ps1 to understand how to set the generator up as a msbuild task.

With symfony console commands you can prefix/group each one by putting in the setName("group:command"), and this is great.
myown
myown:cool
myown:foo
myown:bar
But the problem is that some external dependencies dont use this format. Ex: Phinx Migrations.
Since I'm importing an dependency that has a console command called migrate, I dont want for it to show without prefix/group. Not just because I might have another command called migrate or just for readability. I don't event know if we have 2 with same command name which one will show (need to check).
My question is: Is there any away for me to force a group commands from an external depencency to be inside an prefix/group?
You can achieve that, I wouldn't recommend but that would be the approach:
Create a compiler Pass which removes the definitions of the Commands you don't like
Register again all those commands while setting the names you like
If you need information on compiler passes:
https://symfony.com/doc/current/components/dependency_injection/compilation.html#components-di-compiler-pass
Maybe there's an easier way which I'm not aware, but for now that's my answer to you, I can't post all the code because that would be a lot of code and if you do it maybe you can update with the solution.
Good luck
I hope someone could give me a quick example how to configure the BTLE-Device correctly without the huge BLE-Manager library. Simply a litte GAP Authetication and one GATT-Service would be enough to start. I've managed to create my own GATT-Service and characteristics without the need for BLE-Manager but thanks to several defines, typedefs etc. I can't figure out how to do this for GAP and how to register my callbacks for it. Maybe someone has used these modules before and can give me a quick example how it's done?
Since you mentioned One GATT-Service with Authentication Atmel-BAS [Battery Service] example is easy one. To better understand you can download the getting started guide see the architecture. In-order to register the callbacks you need to check the order of callbacks in function ble_event_manager in ble_manager.c file.
I'm Looking for some samples (will be better if they are open source) that enabling Programmer to Generate UI from Database.
I want to review them for the framework that i want to develop for myself.
Already i reviewed ASP.NET Dynamic Data and Nettiers.
Also i welcome your suggestions , tips , comments.
Have a look at a project I'm about to release, CodeGenerator. There is a sample project which illustrates how you can use CodeGenerator to quickly generate an entire administrative site. Have a look and let me know your thoughts.
BTW, this is just a small example of what CodeGenerator can do.
While perhaps not directly what you may want, have a look at Entity Framework Code First to let the code drive the DB model and it works well with existing databases.
Then with MVC you could use MVCScaffolding to generate your views but in this case it uses the Models not the DB directly.
It's a slightly different way than you might be looking for but it is still worth a look to help you as you look at this.
I have seen several projects that use the Trace functionality to capture events and stream them out to a log file. I have been unsuccessful in finding a simple to follow guide that will show me how to configure Trace to capture and write said logfile. Does anyone have a link recommendations, or provide some simple steps to follow?
The Trace object writes the statements to any attached TraceListeners. You can build your own, but there are a number already defined in the System.Diagnostics namespace, including:
ConsoleTraceListener (Console)
DefaultTraceListener (Visual Studio / Debugger)
DelimitedListTraceListener (TextWriter, special formatting)
EventLogTraceListener (EventLog - anything that inherits from System.Diagnostics.EventLog)
TextWriterTraceListener (TextWriter - think file)
You can, of course, inherit your own from the TraceListener class that writes to where ever you want. For example, you could log to a database, have it send e-mails or pages in certain situations, or write the statements back to a logging platform like log4net.
The big thing is that you need to create an instance of whatever listeners you want and then add them to the Trace' class Listeners collection. You can add as many as you need and Trace will write to all of them. This way, you can write your logging code once using a well-supported and understood object that's part of the framework, and you can attach anything you need to it.
I stumbled into a MSDN article that really helps. Sorry I didn't find it before posting the question but perhaps others may have the same question and haven't found this link.
Take a look at logging frameworks. We rolled out own, but are now migrating over to log4net available free at http://logging.apache.org/log4net/
Im looking for a way to set the Category of the EventLog, the FormattedEventLogTraceListener writes into (not the category of the message).
But I can't find an appropriate property of this class.
Is it possible to set this?
