#Remarks

You can handle this event in the following ways:

#Use the Application Builder

In the application’s Startup.cs file, add the following lines to the application builder code:

File: * MySolution.Blazor.Server/Startup.cs, MySolution.Win/Startup.cs, MySolution.WebApi/Startup.cs

using DevExpress.ExpressApp;
// ...
builder.ObjectSpaceProviders.Events.OnObjectSpaceCreated += context => {
    // Use the `context.ObjectSpace` property to access the created Object Space.
    IObjectSpace os = context.ObjectSpace;
    // ...
};
// ...

#Use the Options Pattern

In the application’s Startup.cs file, call the services.PostConfigure method to configure the ObjectSpaceProviderOptions as shown below:

File: MySolution.Blazor.Server/Startup.cs, MySolution.Win/Startup.cs, MySolution.WebApi/Startup.cs

using DevExpress.ExpressApp;
// ...
services.PostConfigure<ObjectSpaceProviderOptions>(options => {
    options.Events.OnObjectSpaceCreated += context => {
        // Use the `context.ObjectSpace` property to access the created Object Space.
        IObjectSpace os = context.ObjectSpace;
        //...
    };
});
