Invoke Workflow error after migartion from Windows_Legacy to Windows

[Marek_Szwarczewski (Marek)]

Hello!
In my project the workflow is invoked, and several arguments are passed to it. This was working fine in Windows Legacy. After migration I’m getting the error: “Invoke Workflow File: An item with the same key has already been added. Key: VisualBasicValue`1_1”.
Compilation is passed and the error appear during execution. Arguments in invoke activity are as follows

I have googled but find nothing. Any suggestions what I should check? I have no idea where to start my investigation

Hi,

We need to modify xaml file to remove key duplicate VisualBasicValue`1_1 using text editor.

Please see the following post in details.

After Windows Conversion: "Unable to start execution: An item with the same key has already been added. Key: VisualBasicValue `1_1 "

SOLUTION! Took a while to dig into this, but I found that after converting a project from the Legacy framework to the Windows framework, it would not compile the Main.xaml any longer. Eventually, I found that the “VisualBasicValue1_1" key was being used for 2 different transitions. (In addition, "VisualBasicValue1_2” was also being used twice.) The new Windows framework did not like the fact that two transitions were being assigned the same key. (See below.) All I did to fix it was change one…

Thank you @Yoichi !
It is worked. I will never think about edit the xaml file in text editor.
I need increase my search skills as I didn’t find the topic you show me. Thank again!
