UiPath Studio missing namespace

[sjankus (Sarunas)]

Hello,
I can’t find System.Windows.Forms in import namespace. I need to use InputLanguage and can’t do that because it’s missing that namespace. Please help.

I think you can just use the class along with the namespace as System.Windows.Forms.InputLanguage

No. It’s not working. Any other solution?

What version of .Net do you have installed?
I suggest having the latest one but especially 4.7.2 since it is the recommended one for Windows.Forms.
Also be aware that there is a caution on the Windows Forms Page:
“Classes within the Windows Forms namespace are not supported for use within a Windows service. Trying to use these classes from within a service may produce unexpected problems, such as diminished service performance and run-time exceptions.”

I have tried to update .Net from 4.7.0 to 4.7.2 but nothing happens. Maybe there is some another way to check input keyboard language in background?

Hi @sjankus

What is your Studio version and your packages versions? It seems to be working on 2019.4

You could still try this workaround for older versions:

AsEnumerable is not a member of 'System.Data.Datatable'

Hi @lucas.mcgonagle EDIT 20.10 fixed this issue for newly created projects. You can fix it by adding the Assembly Reference manually in your xaml file: [image] Simply open the file in Notepad and create new line with this String: <AssemblyReference>System.Data.DataSetExtensions</AssemblyReference> Then reopen your project and the error should be gone. Please be careful while doing so and always keep a backup.
