Cannot access a disposed object Session when updating a contentItem

[AmadeuAntunes]

I'm trying to update a value in a content Item.

       await ContentManager.UpdateAsync(myContentItem1);

        await ContentManager.UpdateAsync(myContentItem2);

myContentItem1 is not null
myContentItem2 is not null

after call this function and pass my ''myContentItem2' after had called the first time with myContentItem1 I got this error

{"Cannot access a disposed object.\r\nObject name: 'Session'."}

What is the best way to update a ContentItem in orchard ?

Normally this error would happen if you have not awaited something, or if you have resolved the ContentManager in a singleton somewhere, and are then trying to access a disposed session.

The Session (underyling YesSql) and ContentManager are scoped, and disposed at the end of an http request.

Where are you resolving the ContentManager from, i.e. is it a Singleton service somewhere?

I'm getting it by dependence injection from class constructor , Is there any way to get instance from IContentManager

I try use var contentManager = ServiceProvider.GetRequiredService<IContentManager>();but if I try this more then one time I got some error but now in that line System.ObjectDisposedException: 'Cannot access a disposed object.

Well I just replace await ContentManager.UpdateAsync(contentItemSms) to ContentManager.UpdateAsync(contentItemSms).Wait(); and seems work
