    Having pasted your entire file, I receive the following error in VS2019 and the window design does not appear:
    Severity Code Description Project File Line Suppression State
    Error Could not find file ‘C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\ImageName’. WPFUI MainWindow.xaml 2

      Hi Dave,

      I believe that is not a “real” error. Can you run the program, and does it look like it works?

      If the program runs correctly, that error is probably coming from Visual Studio trying to interpret the XAML page, which expects an instantiated Location object, with an ImageName value that points to a location (or monster) file. When you’re editing or compiling the program, and don’t have instantiated objects to bind to, Visual Studio shows that “error”.

      Please let me know if that is not the problem, or if my response is not clear.

        Hi Scott,

        Thanks for your response. The program runs ok.

    Hello, thank you for this huge project. It is a wonderfully helpfull tutorial. I am learning a lot of things and appreciate all the effort and tim eyou invest into this project.
    Hopefully you will find experienced assistance to keep this project alive.

    Something i noticed about the new website. The code area could be somewaht wider. To read most of the code lines, you have to scroll alot sideways. I know there is videos in the first place, but maybe it is not that much needed to widen the text area so more of the code gets visible at once.

    Good luck with the project, i hope to see more videos in the future.
    Is there a .Net6 conversion in planning ?

      SOSCSRPG 2022-04-29

      Thanks Manuel.

      I changed the page layout to be wider. In lesson 191., we convert the solution to .NET 5. I haven’t tried it, but you can probably convert it to .NET 6. I tried to avoid code that only works in specific versions.

        Thanks alot, it is much better to read now.

        Understandable, I have converted my project to .NET6 and it works so far.

        Will this project receive any further lessons in the future? If so, what are you currently working on?

        Again, thanks for this great tutorial.

          I want to add more lessons in the future.

          Right now, I am working on creating a paid course for C# and SQL Server. I’d like to build a business teaching programming. Once I release this course, I’ll have a little time to add some more things to SOSCSRPG, but I don’t know exactly what new changes to make. If you have any ideas what you’d like to see next for the game, please let me know.

    Ok, nice. Looking forward to that course. =)

    Hmm, maybe some of the things already included as future release plans?
    maybe this?
    Armor System? Jewelry System? Echantment System? Buff/Debuff System?
    RPG Style Equipment window, drag and drop Items to slots, prevent items not fitting a slot to be equipped etc.?

      Hi Manuel,

      I released the SQL course at:

      The separate program to manage the game data files might be a good thing to work on next. Although, I’m not sure if it would be better to make the changes to the class files first – since those changes would need to be handled in the game file editing program.

        Hi Scott,

        cool, bought the course. SQL is something that interests me. Haven’t yet spend to much time with it though. So this will come in handy. =)

        Hm, i guess handling the prerequisites first instead of jumping back and forth would be best in my opinion.

          Hi Manuel,

          Thanks for getting the course! It does need a little C# knowledge. But, if you understand classes, properties, functions, collections/lists, and static classes, you should be able to follow all the lessons.

          If you have any suggestions about ways to improve the lessons, please let me know.

    Your tutorial is a highly valuable resource for C# programmers. I’ve learned a lot. Thanks!

      SOSCSRPG 2022-09-12

      You’re welcome! That’s great to hear.

    Happy Fall Scott. I have been following your site and projects over the years. I was wondering if you were ever considering a console version of the second RPG game. Some of us are still on Mac though Visual Studio is getting better on Mac. We could do the console if needed

      SOSCSRPG 2022-10-05

      Thanks Stanley! I’ve tried to think of what to do next with SOSCSRPG, but haven’t come up with anything yet. Well, I’ve come up with a lot of ideas, but haven’t been able to get focused on one yet.

      I do like the idea of a console version. I’ve been writing more of my personal programs as console apps, and that would also allow for writing some natural language processing code.

      I just started a new project for a client, so I know I won’t start anything with SOSCSRPG for at least a few weeks. If I get started on updates for the game, I’ll post here and at the YouTube channel
