Is it possible to call one of my Application Services (that returns a List collection from values from the DB) within a class that inherits from the PermissionDefinitionProvider to dynamically create PermissionDefinition objects? I create an instance of my application service using the **var permissionService = context.ServiceProvider.GetRequiredService(); **statement but after the service calls the supporting repository lookup I get an "Instances cannot be resolved and nested lifetimes cannot be created from this LifetimeScope as it (or one of its parent scopes) has already been disposed."
This same application service/method is used elsewhere in my application without any issues, so it appears to not work when I use it within a class that inherits from the PermissionDefinitionProvider class.
This exception was originally thrown at this call stack: Autofac.Core.Lifetime.LifetimeScope.CheckNotDisposed() Autofac.Core.Lifetime.LifetimeScope.BeginLifetimeScope(object) Autofac.Core.Lifetime.LifetimeScope.BeginLifetimeScope() Autofac.Extensions.DependencyInjection.AutofacServiceScopeFactory.CreateScope() Volo.Abp.Uow.UnitOfWorkInterceptor.InterceptAsync(Volo.Abp.DynamicProxy.IAbpMethodInvocation) in UnitOfWorkInterceptor.cs System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(System.Threading.Tasks.Task) System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(System.Threading.Tasks.Task) System.Runtime.CompilerServices.ConfiguredTaskAwaitable.ConfiguredTaskAwaiter.GetResult() Volo.Abp.Castle.DynamicProxy.CastleAsyncAbpInterceptorAdapter.InterceptAsync(Castle.DynamicProxy.IInvocation, Castle.DynamicProxy.IInvocationProceedInfo, System.Func<Castle.DynamicProxy.IInvocation, Castle.DynamicProxy.IInvocationProceedInfo, System.Threading.Tasks.Task>) ...

I've added you to it.
Run the dbmigrator to create and seed the DB then run the tiered layers

Method
Defineof classPermissionDefinitionProvideris not an async method.You can try this:
public override void Define(IPermissionDefinitionContext context) { var permissionService = context.ServiceProvider.GetRequiredService<IPermAppService>(); var myGroup = context.AddGroup(VoloTestPermissions.GroupName); myGroup.AddPermission(VoloTestPermissions.Dashboard.Host, L("Permission:Dashboard"), MultiTenancySides.Host); myGroup.AddPermission(VoloTestPermissions.Dashboard.Tenant, L("Permission:Dashboard"), MultiTenancySides.Tenant); var permissions = AsyncHelper.RunSync(()=> permissionService.GetPermissionListAsync(new GetPermissionInput())) ; //foreach (var perm in permissions) //{ // myGroup.AddPermission($"{perm.Name}.Allow", L($"{perm.Name}.Allow")); // myGroup.AddPermission($"{perm.Name}.Deny", L($"{perm.Name}.Deny")); } -
