AbpAutoValidateAntiforgeryTokenAttribute

[cgrorhan]

I uploaded aspboilerplate EF version 2.2 to 3.1 and in the startup.cs folder I added this code block ;
services.AddControllersWithViews( options => { options.Filters.Add(new AbpAutoValidateAntiforgeryTokenAttribute()); } ).AddNewtonsoftJson(options => { options.SerializerSettings.ContractResolver = new AbpMvcContractResolver(IocManager.Instance) { NamingStrategy = new CamelCaseNamingStrategy() }; });

but the compiler can not find the AbpAutoValidateAntiforgeryTokenAttribute() , which package or version do I need to install?

Are you talking about aspnetboilerplate?

Yes I figure it out that problem but that came out then ;
'Unhandled exception. System.TypeLoadException: Method 'IsGranted' in type 'Abp.Authorization.PermissionChecker`2' from assembly 'Abp.ZeroCore, Version=4.9.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.'

The version of abp packages in your project should be the same.
