The error
The entity type 'ExtraPropertyDictionary' requires a primary key to be defined
typically occurs when a type that is not meant to be an EF Core entity is being picked up by your DbContext's model builder.ExtraPropertyDictionary
is an internal type used by ABP for extra properties and should not be mapped as an entity.This usually happens if you accidentally add a
DbSet<ExtraPropertyDictionary>
to your DbContext, or if you usemodelBuilder.Entity<ExtraPropertyDictionary>()
in yourOnModelCreating
method. EF Core tries to map it as a table, but it has no primary key, causing the error.
Solution Steps:
Check Your DbContext:
- Ensure you do NOT have any
DbSet<ExtraPropertyDictionary>
in your DbContext. - Do NOT call
modelBuilder.Entity<ExtraPropertyDictionary>()
inOnModelCreating
.
- Ensure you do NOT have any
Review Entity Extension Mappings:
- If you are using ABP's module/entity extension system, make sure you are only mapping your own entities or valid ABP module entities.
- Do not attempt to map or extend
ExtraPropertyDictionary
.
Clean and Rebuild:
- Clean your solution and rebuild to ensure no old artifacts are causing the issue.
Check for Accidental Usages:
- Search your solution for any accidental references to
ExtraPropertyDictionary
in your entity or DbContext code.
- Search your solution for any accidental references to
If You Need to Add Extra Properties:
- Use ABP's recommended way to extend entities, as described in the documentation below.
Example for extending an entity (do NOT use
ExtraPropertyDictionary
directly):ObjectExtensionManager.Instance.Modules() .ConfigureIdentity(identity => { identity.ConfigureUser(user => { user.AddOrUpdateProperty<string>("CustomProperty"); }); });

hi
Can you share your
DbContext
class code?Maybe https://github.com/abpframework/abp/issues/14498#issuecomment-1298061321 will help.
Thanks
