I am Copying XAML file which I have developed previously into another folder which I am presently working on.Whenever I am trying to open that copied XAML file in Uipath It is showing below error


I have deleted and copied again but every time I am facing the same issue. Can anyone please help me with this issue?


UiPath Compatibility with code developed on Old version
#2

Things to look out for if you’re migrating files from older to newer versions of UiPath

missing packages
uipath.core namespace
genfour.activities namespace
in the xaml replace <ua: tags with <ui:
in the xaml check for encoding="{x:null}" (usually in read/write csv activities)
delete genfour.utitlies namespace (has an error sign)
install v7 compatability
resolve businessruleexception by adding the full path e.g. uipath.core.BusinessRuleException


UIpath studio license
REFramework xaml errors
#3

Thanks @richarddenton the issue got resolved as I updated all the available packages …
