Hi Everyone,

I have recently installed Custom Packages build by out client in one of my projects.Since then im getting below error during Compiling.Unexpected error has occurred during the library compilation process:

Unable to create activity builder for Main.xaml. Reason was ‘No matching constructor found on type ‘System.Activities.Activity’. You can use the Arguments or FactoryMethod directives to construct this type. No default constructor found for type ‘System.Activities.Activity’. You can use the Arguments or FactoryMethod directives to construct this type.’.

Could anyone help on this please?

Hi @Aswini

Could you check if the Dependencies are compatible? The dependencies used to develop the custom activity may not be the same as your project.
