I got a Blazor page with following form submit button
<button type="submit" class="btn btn-primary" @onclick="@(async()=> await OnCreateItem())">Create </button>
Which calls
protected async Task OnCreateItem()
{
try
{
var result = await dbMgr.CreateAsync(item);
}
catch (Exception ex)
{
Throws ==> Cannot access a disposed object. A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose()...
}
}
dbMgr is injected to the page
@inject DBManager dbMgr;
And manager is implemented as
class DBManager
{
...
public DBManager(DBContext db)
{
_db = db;
}
public async Task<int> CreateAsync(ItemModel obj)
{
await _db.AddAsync(obj);
return await _db.SaveChangesAsync()
}
}
Startup class is
public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
services.AddServerSideBlazor();
services.AddDbContext<DBContext >(options =>
options.UseSqlServer(Configuration.GetConnectionString("DBContext")), ServiceLifetime.Scoped);
services.AddScoped<DBManager>();
}
I read a similar questions here Link 1 Link 2
To no avail.
Not sure what am I doing wrong.
