I'm trying to create an IronPython WPF form on Visual Studio 2019. However, when I try using the XAML Designer to edit the text of my button, I get this error saying "System.ArgumentNullException Value cannot be null. Parameter name: source." It allows me to reload the designer, but then the error simply occurs again when I attempt to edit the text. You can find the full error and my .XAML file below.
Error:

You have multiple SET in your query. Change it to
insertsql = "UPDATE RepairOrders SET ROOther = #Other,
ROJobType = #Type, ROJobTime = #Time, RODelPicDate = #DelPic WHERE RONo = #JobNo"

This exception is thrown on very specific pages, so it's not randomly distributed across the application. One of these pages makes a simple query to the database through Entity framework using a table function. The table function is named "GetPeopleNames" and our ObjectContext class is the one named "SiteEntities".
public class PeopleGetter : IPeopleGetter
{
public List<object> GetResult()
{
using (var siteEntities = new SiteEntities())
{
IQueryable<someResultEntity> result =
siteEntities.GetPeopleNames()
.SortBy("Name", "asc")
.Skip(20*query.CurrentPagingPosition)
.Take(20);
List<People> people = SelectResultToPeople(result)
return people;
}
}
private List<People> SelectResultToPeople(IQueryable<someResultEntity> result)
{
return result
.ToList()
.Select(x => new People { })
.ToList();
}
}
I can't see why it should have something to do with our fault, but i'd better mention that PeopleGetter class is resolved and created by Unity IoC container. The PeopleGetter is registered with a 'PerRquest' LifeTimeManager like this:
public class PerCallContextLifeTimeManager : HierarchicalLifetimeManager
{
private readonly string _key = string.Format("PerCallContextOrRequestLifeTimeManager_{0}", Guid.NewGuid());
public override object GetValue()
{
if (HttpContext.Current != null)
return GetFromHttpContext();
else
return base.GetValue();
}
private object GetFromHttpContext()
{
return HttpContext.Current.Items[_key];
}
public override void SetValue(object newValue)
{
if (HttpContext.Current != null)
SetInHttpContext(newValue);
else
base.SetValue(newValue);
}
private void SetInHttpContext(object newValue)
{
HttpContext.Current.Items.Add(_key, newValue);
}
public override void RemoveValue()
{
}
}
Any ideas why we're getting closed connections?
Thanks for you help!
Can somebody explain what exception bellow means? It occurs when InitializeComponents is executed in my WPF user control constructor. I'm using .net4, in case it's version specific. I realy don't have a clue what should I search for.

Without reading through all 2 thousand lines.
When you see System.Reflection.TargetInvocationException it means that a function that is being called from a delegate threw an exception.
It looks like you are assigning an invalid a root instance to the ShortcutsManagementOptionsPanel.
Cannot assign root instance of type 'ShortcutsManagementOptionsPanel' to type 'ShortcutsManagementOptionsPanel'.
In Visual Studio make sure to set Debug > Exceptions > Break on CLR exceptions "Thrown"
You will likely get a more meaningful exception this way.
