I am working with UiPath Community version (2025.0.25), my previous workflows are under Windows-legacy. Now, the current version made it mandatory to update the workflow to “Windows”. While converting and compiling my resource, i am facing few challenges:

Unexpected error has occurred during the library compilation process:
The assembly compilation returned the following errors from"Main.Xaml"

  • (5328) : error BC31061: property ‘Get_OriginalAmount’ conflicts with a member implicitly declared for property ‘originalamount’ in class ‘Main_Expressions_TypedDataContext2’.
    [Note: Orginalamount = System.text.regularExpression.Regex.Match(Get_OriginalAmount,“\d+”).Tostring]

I have tried to updated with matches activity but still no luck.

Please help.

Thanks for the all help! @mkankatala @Anil_G

I have found the solution. Just updated the sequence them into new workflow and moved the variable to arguments from main .Xmal.

updated all the existing package with latest version.
