Description
Hi
I am getting this error
Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.
at System.Collections.Generic.Dictionary`2.FindEntry(TKey key)
at System.Collections.Generic.Dictionary`2.TryGetValue(TKey key, TValue& value)
at Mapster.TypeAdapterConfig.Remove(TypeTuple key)
at Mapster.TypeAdapterConfig.NewConfig[TSource,TDestination]()
at InventoryService.GetCategories(Int32 inventoryCenterId)
at Controllers.InventoriesController.GetCategories(Int32 centerId)
The code it is pointing to is this
TypeAdapterConfig<Category, CategoryDto>
.NewConfig()
.IgnoreIf((src, dest) => string.IsNullOrEmpty(src.MetaTitle), dest => dest.MetaTitle)
.IgnoreIf((src, dest) => string.IsNullOrEmpty(src.MetaDescription), dest => dest.MetaDescription);
var categories = dbContext.Centers.Where(x => x.Id == CenterId).SelectMany(x => x.Categories).OrderBy(x => x.Name).ToList();
return categories.Adapt<List<CategoryDto>>();
Starting and stopping IIS fixes this for a certain amount of time and then it comes back.
I found these related issues
DuendeArchive/IdentityServer4#2453
but I am using 2.2 for Aspnet Core and Ef Core 2.2.4 and they where using older versions.
edit
I ran on the the server this opersation
(dir (Get-Command dotnet).Path.Replace('dotnet.exe', 'shared\Microsoft.NETCore.App')).Name
and I am getting version 2.2.5
