How to use Try Catch Finally to dispose garbage

I am having garbage collection issues on my application which is built using Abp 1.5.1. Please is there a way to dispose of garbage using the code below?

try
                {
                        entries = _ventryRepository.GetAll().Where(x => x.CustReference == custRef)
                                .OrderBy(x => x.Id)
                                .Skip((page - 1) * pageSize)
                                .Take(pageSize);
                            longCount = _ventryRepository.GetAll().Where(x => x.CustReference == custRef).LongCount();
                        
                }
                catch (Exception e)
                {
                    return new TransactionHistoryResponse
                    {
                        CustomerId = custRef,
                        StatusCode = 1,
                        Message = message
                    };
                }
            });

What exactly can I dispose of here in a finally() block? I want to dispose of as much possible without breaking the application.

Thank you

In general, you should not dispose an object while using dependency injection.

What is your framework, AspNet Core? Can’t you upgrade to latest ABP since your version is a bit old to provide support.
