NT8 freeze on VS debug mode ?

[devdas]

Hello,

Why NT8 (8.0.22.2) freezes during debug mode ? Why am I seeing these black docks on each window in NT8 ? Is this normal ?
Nothing is manually interactable in NT8 during this behavior.
What is XAML Binding Failure means on bottom left corner of VS screen ?

Hello devdas,

The black bars on the window are part of visual studios xaml debugging tools. You can just turn that feature off in visual studio if you dont want to see it. In the Options choose Debugging -> General and Uncheck Enable UI Debugging Tools for XAML (towards the bottom of the list). The way NinjaScript can use xaml makes these tools not very useful in NinjaTrader, they would generally be used in your own external WPF application during development.

The interface should be frozen if you are using breakpoints or have paused execution in visual studio. Debug mode allows visual studio to attach to the process and break execution when you are debugging it. In your image you can see the execution is paused, the Continue button is present in the toolbar.

The xaml binding failures would be only helpful in your own external WPF applications. You could research that in Microsoft documentation if it is something you may want to learn more about how its used. Generally none of the xaml tools in visual studio will work directly with NinjaScript due to how xaml needs to be designed when used from NinjaScript.

I look forward to being of further assistance.

Hi. I am facing the same problem - when I start debugger in Visual Studio, I can't interact with NT windows, they don't react on my actions. I am using Visual Studio Community 2019 (version 16.10.4) and NinjaTrader 8.0.24.0. I disabled UI debugging (in HOT reload section) and I don't see any black boxes but still can't do anything with NT (I need to set breakpoint and then launch my strategy in a backtest mode but can't click the button "run").

Hello alvik48,

Are you seeing the "Continue" button in the visual studio toolbar? If the execution is paused then what you described is normal.

I look forward to being of further assistance.

No, the "Continue" button is disabled. When I stop debugging, NinjaTrader becomes active again.

Hello alvik48,

You may want to try and reset the visual studio settings to default to check if that helps. I am not aware of what else would cause the platform to be locked except for pausing the execution while attached. That would occur based on breakpoints or using the pause in visual studio.

I look forward to being of further assistance.

So restart of both NT and VS helped, now everything works (without reset of any settings).
