C# User Controls - VB.Net page

Question

Hi, I am leading two application teams at the same time. The first application has the presentation layer in ASP.NET using C# in the code-behind file. The other team uses VB.Net. If User Controls are developed in C#, can they be used in an ASP.Net page which has it's code behind file in VB.Net ? Any know issues / problems ? An urgent response would be greatly appreciated !
