Window legacy conversion issue

[winnie_toh]

Dear all, i managed to convert my bot from window legacy to windows. But when i run, it stated compilation error as follows which i read i need to update activities.:

kindly advise how can i update the activities?

JIT compilation is disabled for non-Legacy projects. ExpressionToCompile { Code = "System.Activities.InArgument1[System.String]", ImportedNamespaces = System.Collections.Generic.HashSet1[System.String], VariableTypeGetter = System.Func`2[System.String,System.Type], LambdaReturnType = System.Object } should have been compiled by the Studio Compiler.

Hi @ppr, really helpful tutorial, thanks for sharing!

Dear @ppr Thank you for sharing!! But it looks complicated to a noob like me.

Meanwhile, i will be left with the option to continue to use the Window Legacy bot.

Do you foresee there will be issues if i continue to use that old version which is still running?

Thank you so much in advance!

Hi,

@winnie_toh

Do you foresee there will be issues if i continue to use that old version which is still running?

It’s announced Windows-legacy compatibility for new projects will be deprecated in 2023.4. However we can run and modify existing project in 2023.4 at least. So, it’s no problem to use Windows-Legacy for a while.
