Windows converted project now not running (Jan. 2023)

[Kyle_Shahenian]

Have 22.10 installed on one of our test VMs and I’m trying to run one of our rebuilds (using ReFramework) on it but it keeps erroring out before execution.

After opening the “legacy” build, Studio prompted me to convert it to a Windows-compatible one so I did. There were 2 libraries that this project used that also had to be converted so I did that as well as deployed a Windows version of the same libraries. Got all the dependencies updated and ensured there were no validation errors. Now debugging, I get this error.

22.10.4+Branch.support-v22.10.Sha.b4be88e3b45fb05c4bcd71885c763d4f2095f959

At first I thought I might have screwed something up while converting so I deleted the project, reopened the legacy one, then re-converted it to a Windows-compatible version. Rechecked the dependencies & validation errors and both were in order. Went to debug and got the same error message as above.

The project in question IS referencing a Config dictionary but there’s no difference between how it’s being initialized, populated with data, and output so I don’t know what the cause could be with this issue. Can someone help me out here?

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…
