Copying localization resources to the output folder is a standard behavior for assemblies which support localization. When you create a Telerik UI for ASP.NET MVC VIsual Studio project there is by default four references to assemblies which support localization and copy such folders and these are:
(The last three assemblies are part of Microsoft ASP.NET Web API OData package)
If you really don't want these localization folders copied you can follow these steps to delete the localization resources folders for each referenced assembly:
When you do these steps for each of the four referenced assemblies there will be no more copying of the localization resources in the bin folder but your application will not support localization anymore.
- Get the path to the assembly by looking in the properties of the reference to this assembly in your project.
- Navigate to this path. You will see the assembly and many folders containing localization resources for each language.
- Delete these localization resources folders.
I hope this will help you.
