This is where the shadow properties are added to the model.
ITenantId for filtering, ITenantEntity for creating a clustered index and filter; that way I can pick and choose which get a clustered index. Gets an EntityEntry for all entities of a given type being tracked by the context.
Analysis of native system services e. No tracking queries are useful when the results are used in a read-only scenario.
MakeGenericMethod t ; method. I hope you will find these techniques as useful as I have! This means the change tracker will keep track of changes for all entities that are returned from a LINQ query.
Tracking vs. No-Tracking Queries
Not all malicious and suspicious indicators are displayed. Gets or sets the tracking behavior for LINQ queries run against the context.
You should not disable change tracking if you want to manipulate entity instances and persist those changes to the database using SaveChanges.

There are two cases: I only set these for the top level objects For detail tables, the clustered index goes on the parent id I separated it into two TenantId related interfaces: The default value is true.
Entity Framework Core – Automate all that boring boiler plate! – Trailhead Technology Partners
The call to SetGlobalQueryFilters follows the chzngetracker basic pattern, iterating over the types in the model and calling generic methods on those classes satisfying the marker interface requirements:. However, If i change the Ninject Binding for the DbContext to a Singleton, the code works fine, the change is tracked and the object is saved to the database. We want to automate how this happens. I think this is all in the article, did I miss something?
