Returning Generic Type from a CreateInstance Method

I seem to be having trouble finding a way to cast & return an Activator-created instance as its generic type. I have looked at various examples...but cannot seem to find an "exact" example for what I am trying to accomplish.

• How do I return the correct type from the GetRepositoryInstance method below?

For instance...

public class GenericRepository<TEntity> : IRepository<TEntity> where TEntity : class
{

}

public class TransactionProvider : ITransactionProvider
{
    public void AddPending(ITransaction transaction)
    {
        // Get the targeted types
        var typeEntity = GetTransactionEntityType(transaction.EntityName);
        var typePendingEntity = GetTransactionPendingEntityType(transaction.EntityName);

        // Get the Repository Instances for each type
        var repositoryEntity = GetRepositoryInstance(typeEntity);
        var repositoryPendingEntity = GetRepositoryInstance(typePendingEntity);
    }

    // -----
    // HERE...I want to return the generated type as its' IRepository<>...how?
    // -----
    private IRepository<> GetRepositoryInstance(Type entity)
    {
        var repositoryType = typeof(GenericRepository<>).MakeGenericType(entity);
        var repository = Activator.CreateInstance(repositoryType);

        return repository;
    }
}
