What is the XAML code you tried to add it with? Did you take a look at the example code?
Hi,
Ofc i tried the example code but i got the same error. Today i tried it on an other computer so i believe it's in the code or i'm doing something wrong :(.
Here is the XAML code added automatically :
<Window x:Class="OpenTkControlExample.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:openTkControl="clr-namespace:OpenTkControl;assembly=OpenTkControl"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<openTkControl:ThreadOpenTkControl x:Name="OpenTkControl" GlRender="OpenTkControl_OnGlRender" ExceptionOccurred="OpenTkControl_OnExceptionOccurred"/>
</Grid>
</Window>
The control can't render properly within the designer view, but it should work fine when you actually run the code. The easiest solution to this issue is disabling project code in the designer. See this for more information: https://docs.microsoft.com/en-us/visualstudio/designers/debugging-or-disabling-project-code-in-xaml-designer?view=vs-2017 Alternatively, you can modify the code to add checks to see if its running in the designer and disable anything that calls a function that won't work properly.
Could this merged fix be updated on NuGet?
@rickberkers Yes, I'll try to get the other PR merged and then put this on NuGet sometime this weekend.
Hey,
When i try to add both UIOpenTKControl or threading one into the designer of my C# apps, it gives me an error :
"ArgumentNullException : Value can't be null. Parameter name : window"
I think it's making some trouble on my XAML code. Tried to fixe it but i didn't find the solution. I tried to reinstal everything. Same error occurs with the example solution. BackTrace is :

Thank you very much,
