I'm sorry, your question makes no sense. First of all, this is an English speaking site so please post questions in English. Second, when I translated your question, it said:
P.... didn’t save Editor3D_Render_Control for 2022 MS VStuio What does that even mean?

What did you use to translate? Google produces "screw up" instead of "save" for me.

If you mean this control: Editor3D: A Windows.Forms Render Control with interactive 3D Editor in C#[^] then don't post this under a "generic" forum like C# - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

In VS 2022 I can not find any templates for WinUI. I installed Windows SDK and WinUI controls but I can not find any templates. Any idea why ?
Thanks

Hello friend! I am developing a Windows application (WinForms) to manage universities with c#, it is an application that is very complex because it is a Multi-user application, I want that for this application I can use a single database centralized by all users of this application, which will be managed by myself and my development team. Is this possible? What would be the best and least expensive solution, taking into account my capacity? Also in terms of cost, between a SQL SERVER EXPRESS database and a MySQL database, which one might be better for me? And which one is well suited to C#, using Crystal Report and Visual Studio as well? Your answers will help me a lot to make a decision and also develop an efficient solution.
I'm thinking about whether it's possible to host only my SQL SERVER EXPRESS, or MySQL database to which my Windows software or application designed in C# can connect remotely so that the various users of my device can access the remote database
Thank you for your help

You didn't specify anything about capacity.

Manage what? Class schedules? Budgets? Lawn care?
theo tuombe wrote: What would be the best and least expensive solution
No idea. Even if you had all of the missing detail anyone that claimed that they could decide both of those would be, let us say, less well informed about the subject than one might hope.
theo tuombe wrote: And which one is well suited to C#
This is one of those factors where "best" has many meanings. If you plan on being a windows shop then staying with windows which means SQL Server is probably going to be the least amount of trouble.
Now if you or others that work on this have experience both in C# and other data persistence stores then there are other options. But then I suspect you would have already been able to evaluate that without asking here.
If you are VERY careful with how you write your code and your design then it is possible that you can switch databases relatively easily if you find you want a different solution. But unfortunately that again is probably dependent on experience.

Thank you very much Dear jschell for your answer to my question posed in the forum.
"taking into account my capacity?" I mean taking into account the cost,
"managing universities with c#" is really the input errors. To be clear with my question, I wanted to ask that I develop a WinForms application to manage universities with the programming language c#, the application I develop is an application that must manage the entire university including student management, budget management, course management etc.. It's an application that I want, after development, to be able to deploy to different universities, which are then the end users of my application. So I'm asking what solution I can use so that my application installed on different users' computers can use a single database! without error connection to database??
Thank you

This is an extremely ambitious project for someone that doesn't know most database engines are already multi-user capable. The trick is writing your code correctly, so you don't introduce concurrency problems.
Why would you write a multi-user app like this as a desktop app and not as a web app? The one thing you forgot to mention in your description is security for these areas and data.
Do you even know what products universities already use for such management operations? Do you know that is your competition? Do you understand the market at all?

You already said that. Saying it again doesn't change the answers.
For such a massive project, you don't know what you're doing. Just the fact that you even mentioned SQL Server EXPRESS shows you are on a newb level with no idea the scale of the project you're describing.
Think of it this way. You're at a construction site, looking at a very small pile of bricks, trying to ask "how do I build a 100-story skyscraper?" You simply don't understand the scale of the project or the even the requirements of your own idea!
You want a database engine recommendation? Sure. How about SQL Server Enterprise or Oracle Database Enterprise.

Yes, thank you very much.
I'm not at all an expert in development software, and my experience is limited. In fact, I'm looking for a database engine solution that can work well with this project as I've described it. I was also looking for a database engine that can easily work with C# and Crystal Report because I'd like to use Crystal Report for Reports, and also a database engine that grants the possibility to be deployed either on a server or on a cloud, finally that the application install on different computers users use and access this database that is deployed on a remote server or on cloud.
Your recommendations, suggestions and advice will help me great and will also enable me to develop high-performance software.
Thank you

And that's why this project is WAY beyond your reach. You simply don't understand the scale of what a university needs to manage all of its operations and how that translates to requirements for your application.
theo tuombe wrote: 'm looking for a database engine solution that can work well with this project as I've described it
Your description is extremely vague at best, and the best suggestion you're going to get is any enterprise database engine.
theo tuombe wrote: I was also looking for a database engine that can easily work with C# and Crystal Report
Database engines do not care at all what language you use to write your application code.

As the others said. It is too big.
I have decades of experience and it would be pointless to attempt this without a well funded company which included years of capital and I expect multiple domain experts.
You can however start by designing ONLY a class management project.
Part 1
1. You must be able to enter the classes at the beginning of a semester. Name of class, Name of teacher, Building, room.
2. Time of the class. Must be able to specify days of week, time of day
3. Must be able to schedule mid terms and final schedules for different times and locations. This is optional since some schools do it and others do not.
4. Must be able to provide url for remote attendence.
5. Provide last sign up date and time.
Part 2
1. Students must be able sign up for class.
2. Class can not exceed size
3. Waiting list must exist.
4. Students must be signed up before sign update date.
Part 3
1. Student must be able to get a report of classes and waiting lists
2. Teacher must be able to get a report of all classes and waiting lists for each.
Part 4
1. Teachers and students must exist in the system. They must be able to log in and log out
Working on above
1. Figure out how a database works. Does not matter which one.
2. Figure out how to make a UI
3. Figure out has to make a client server application. (There are other ways these days but they still are based on this idiom.)
4. Figure out how to securely handle log in/out.
5. Figure out how to tie a UI to a backend.
6. Figure out how to tie a backend to a database.
7. Figure out how to test all of this.

Look for a project which you can actually succeed at. This is not such a project. Universities already use other products and they will not switch to yours, you have no hope of entering the market.

This statement reveals a serious lack of understanding of software applications.

No, that isn't happening. Too expensive for a university.
theo tuombe wrote: access the remote database
Offsite? No mission-critical application should rely on connectivity to resources which are remote.
