    Umbraco 8.6.0. Cannot access a disposed object. Object name: 'snapshot'.

    Hi! I am updating umbraco from 7 to 8 version. I got this piece of code in my project:

    public class TypedPublishedContentQuery : IPublishedContentQuery
        {
            private static readonly Mapper __mapper = new Mapper();
        private readonly IPublishedContentQuery __typedPublishedContentQuery;
        private readonly PublishedContentTypeResolver __publishedContentTypeResolver;
    
        public TypedPublishedContentQuery()
            : this(new PublishedContentQuery(Current.UmbracoContext.PublishedSnapshot, Current.UmbracoContext.VariationContextAccessor))
        {
    
        }
    
        public TypedPublishedContentQuery(IPublishedContentQuery typedPublishedContentQuery)
        {
            this.__publishedContentTypeResolver = new PublishedContentTypeResolver();
            this.__typedPublishedContentQuery = typedPublishedContentQuery;
        }
    
        public IEnumerable<T> TypedContent<T>(IEnumerable<int> ids)
            where T : class, IPublishedContent
        {
            return this.__typedPublishedContentQuery.Content(ids)
                                                    .Select(typedContent =>
                                                        this.CreateTypedPublishedContent<T>(typedContent)
                                                    )
                                                    .Where(typedContent =>
                                                        typedContent != null
                                                    );
        }
    
        public IEnumerable<T> TypedContent<T>(IEnumerable<Guid> ids)
            where T : class, IPublishedContent
        {
            return this.__typedPublishedContentQuery.Content(ids)
                .Select(typedContent =>
                    this.CreateTypedPublishedContent<T>(typedContent)
                )
                .Where(typedContent =>
                    typedContent != null
                );
        }
    
        IEnumerable<IPublishedContent> IPublishedContentQuery.Content(IEnumerable<int> ids)
        {
            return this.TypedContent<IPublishedContent>(ids);
        }
    
        public IEnumerable<IPublishedContent> TypedContent(IEnumerable<Guid> ids)
        {
            return this.TypedContent<IPublishedContent>(ids);
        }
    
        public T TypedContent<T>(int id)
            where T : class, IPublishedContent
        {
            var publishedContent = this.__typedPublishedContentQuery.Content(id);
            if(publishedContent == null)
            {
                return null;
            }
    
            var typedContent = this.CreateTypedPublishedContent<T>(publishedContent);
            if(typedContent == null)
            {
                return null;
            }
    
            return typedContent;
        }
    
        public T TypedContent<T>(Guid id)
            where T : class, IPublishedContent
        {
            var publishedContent = this.__typedPublishedContentQuery.Content(id);
            if (publishedContent == null)
            {
                return null;
            }
    
            var typedContent = this.CreateTypedPublishedContent<T>(publishedContent);
            if (typedContent == null)
            {
                return null;
            }
    
            return typedContent;
        }
    
        IPublishedContent IPublishedContentQuery.Content(int id)
        {
            return this.TypedContent<IPublishedContent>(id);
        }
    
        public IPublishedContent TypedContent(Guid id)
        {
            return this.TypedContent<IPublishedContent>(id);
        }
    
        ......
    

    }

    After upgrading, When I run the project and starting page opens up for the first time, there is no issues. But if I reload the page i got "Cannot access a disposed object. Object name: 'snapshot'. " issue. Or if I try to open other pages. Can't find where is the problem and why snapshot gets disposed. Would be grateful for any help.

    Juris, Take a look at the discussion here: https://github.com/umbraco/Umbraco-CMS/issues/5073

    seems to be a similar issue.
