I would be a lot less messy if I could have only type of objects (but I will need more of them because I need some additional formatting before saving value to object - for exampe: string can only include numbers) Yeah, I know that reflection is usually better to be avoided, but this is currently the best idea I got, haha

and loading is like this: 
public async Task GetSettings() {
    var fileContent = await File.ReadAllTextAsync("config.json");
    var fds = JsonSerializer.Deserialize<Dictionary<string, JsonElement>>(fileContent);            
    foreach (var property in this.GetType().GetProperties().Where(x => typeof(CanvasPosition).IsAssignableFrom(x.PropertyType) && x.CanWrite))
    {
        if (fds.ContainsKey(property.Name) && typeof(CanvasPosition).IsAssignableFrom(property.PropertyType))
        {
            var jsonValue = fds[property.Name];
            var value = JsonSerializer.Deserialize(jsonValue.GetRawText(), property.PropertyType);
            property.SetValue(this, value);
        }
    }
}
public async Task GetSettings() {
    var fileContent = await File.ReadAllTextAsync("config.json");
    var fds = JsonSerializer.Deserialize<Dictionary<string, JsonElement>>(fileContent);            
    foreach (var property in this.GetType().GetProperties().Where(x => typeof(CanvasPosition).IsAssignableFrom(x.PropertyType) && x.CanWrite))
    {
        if (fds.ContainsKey(property.Name) && typeof(CanvasPosition).IsAssignableFrom(property.PropertyType))
        {
            var jsonValue = fds[property.Name];
            var value = JsonSerializer.Deserialize(jsonValue.GetRawText(), property.PropertyType);
            property.SetValue(this, value);
        }
    }
}

Okay, so I managed to do some "improvements", which include less hardcoding stuff. I have two models, CanvasPosition and StringCanvasPosition (this one inherits canvas position - some elements requires string, some int, so I just separated them. 
public class CanvasPosition 
{
    public double? CanvasLeft { get; set; }

    public double? CanvasTop { get; set; }
    public string BindableName { get; set; }
}


public class StringCanvasPosition : CanvasPosition
{
    public string TextValue { get; set; }
}
public class CanvasPosition 
{
    public double? CanvasLeft { get; set; }

    public double? CanvasTop { get; set; }
    public string BindableName { get; set; }
}


public class StringCanvasPosition : CanvasPosition
{
    public string TextValue { get; set; }
}
Then I have bindable properties like this: 
private StringCanvasPosition _receivedRequestsWrapper { get; set; }
public StringCanvasPosition ReceivedRequestsWrapper ....getter, setter...
private StringCanvasPosition _receivedRequestsWrapper { get; set; }
public StringCanvasPosition ReceivedRequestsWrapper ....getter, setter...
For the serialization and deserialization I used reflection. I am saving it to File and the code looks like this: Saving: 
Dictionary<string, object> dict = new Dictionary<string, object>();
foreach (var property in this.GetType().GetProperties().Where(x => typeof(CanvasPosition).IsAssignableFrom(x.PropertyType)))
{
    dict[property.Name] = property.GetValue(this);
}
var options = new JsonSerializerOptions
{
    WriteIndented = true
};
var jsonString = JsonSerializer.Serialize(dict,options); ;
File.WriteAllText(file, jsonString);
Dictionary<string, object> dict = new Dictionary<string, object>();
foreach (var property in this.GetType().GetProperties().Where(x => typeof(CanvasPosition).IsAssignableFrom(x.PropertyType)))
{
    dict[property.Name] = property.GetValue(this);
}
var options = new JsonSerializerOptions
{
    WriteIndented = true
};
var jsonString = JsonSerializer.Serialize(dict,options); ;
File.WriteAllText(file, jsonString);

oh, when I was typing, this thought occured me,actually it might even work, will test it tommorow morning. If you are OK with that, can I ask you some questions if they will be needed?

Okay yeah, I had started with something similar and managed to make it work, which is nice. Thank you! (I should look into stuff like "sealed record", "abstract", "immutableDictionary") Haha ye, every new way of storing data ends totally ugly... well, the above way with hardcoding every property kinda works, maybe some better idea will pop in my mind anytime soon.. It technically works, except some properties have margin set in XAML and on fresh set of X and Y form file, their margin stays there and its location is actually wrong. An easy "fix" would be get rid of margins, but yea 😅

Also, if I would like to store them into a json file and do loading from there like this 
SpecialBindableObject MyTextBox1;
SpecialBindableObject MyTextBox2;
SpecialBindableObject Label1;
...
Dict<stirng, SpecialBindableObject> savedObjects = deserializeJsonContent from file
and then for each property something like:
MyTextBox1 = savedObjects["MyTextBox1"];
MyTextBox2= savedObjects["MyTextBox2"];
Label1= savedObjects["Label1"];
SpecialBindableObject MyTextBox1;
SpecialBindableObject MyTextBox2;
SpecialBindableObject Label1;
...
Dict<stirng, SpecialBindableObject> savedObjects = deserializeJsonContent from file
and then for each property something like:
MyTextBox1 = savedObjects["MyTextBox1"];
MyTextBox2= savedObjects["MyTextBox2"];
Label1= savedObjects["Label1"];
How ungly is that? 😅

And instead of binding 3 different variable, I can use only one, and do binding in xaml likeSpecialObject.PositionX, SpecialObject.PositionY, etc?

So some kind of SpecialBindableObejct with at least 3 properties (value, PositionX, PositionY) and INotifyPropertyChanged

How do you implement paging on API requests?
So all service methods shoudl be something like this, or is it any easier/better way? 
 public async Task<List<BlogPosts>> GetBlogposts(int? page, int? pageSize)
 {
     if (page.HasValue && pageSize.HasValue)
     {
         await context.Blogposts.OrderBy(p => p.ReleaseDate).Paginate(page, 20).ToListAsync();
     }
     await context.Blogposts.OrderBy(p => p.ReleaseDate).ToListAsync();
 }
 public async Task<List<BlogPosts>> GetBlogposts(int? page, int? pageSize)
 {
     if (page.HasValue && pageSize.HasValue)
     {
         await context.Blogposts.OrderBy(p => p.ReleaseDate).Paginate(page, 20).ToListAsync();
     }
     await context.Blogposts.OrderBy(p => p.ReleaseDate).ToListAsync();
 }

Aha, ok. so User service would have something like this: private DbContext _myDbContext 
GetUserByName(stirng name) => _myDbContext.Users.FirstOrDefault(x => x.Name == name);
GetUserByName(stirng name) => _myDbContext.Users.FirstOrDefault(x => x.Name == name);
