Servicestack Test: Method not found: 'Int32 ServiceStack.DataAnnotations.CustomFieldAttribute.get_Order()

Trying to build integration test with connection to db in ServiceStack.
My ServiceStack app is working fine, but when I run simple test I got this error message in line:22
System.MissingMethodException: 'Method not found: 'Int32 ServiceStack.DataAnnotations.CustomFieldAttribute.get_Order()'.'
There is a lite cod:
using ServiceStack;
using ServiceStack.OrmLite;

container.Register<IDbConnectionFactory>(c =>

using var db = container.Resolve<IDbConnectionFactory>().Open();
db.CreateTableIfNotExists<Customer>();

Anytime you see a missing type or missing method exceptions when using the MyGet pre-release packages it means you have a dirty installation (i.e. using pre-release packages from different build times).
In which case you'd need to Clear your Nuget packages cache and download the latest packages again, which ensures all your packages are from the latest same build:
$ dotnet nuget locals all -clear

Unable to resolve service for type while attempting to activate a service in startup.cs

Have spent way too much time trying to figure this out. Thanks for any help. .Net Core 3.1 trying to register a service in Startup.cs
Error CS0311: The type 'Apex.UI.MVC.ProjectService' cannot be used as type parameter 'TImplementation' in the generic type or method ServiceCollectionServiceExtensions.AddScoped<TService, TImplementation>(IServiceCollection). There is no implicit reference conversion from 'Apex.UI.MVC.ProjectService' to 'Apex.EF.Data.IProjects'. (CS0311) (Apex.UI.MVC)
services.AddScoped<IProjects, ProjectService>();
using System;
using Apex.EF.Data;
using Microsoft.AspNetCore.Mvc;

}
public Project GetById(int id)
{
return _context.Projects
.Include(project => project.Status.IsInShop==true)
.FirstOrDefault(project => project.Id == id);
}
}
}

The namespaces shown in the exception are different to the example code shown. There are probably conflicting types in the project (not shown).
If that is really the case, then include the full namespace when registering the type with the container to avoid conflicts.
Based on the shown code, that would be
services.AddScoped<IProjects, ApexServices.ProjectService>();

unable to save the inserted data after mapping

I'm trying to create a very simple C# program for insert the data.
Here is the service file :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using AutoMapper;
using DataAccess;
using DataAccess.UoW;
using Model;
namespace ClassLibrary1
{
public class Service
{
private readonly Unit _uow;
public Service()
{
_uow = new Unit();
}
public bool CreateEmp(Mdl insertEntity)
{
var config = new MapperConfiguration(cfg =>
{
cfg.CreateMap<Mdl, Table_1>();
});
IMapper mapper = config.CreateMapper();
var Empinsert = mapper.Map<Mdl, Table_1>(insertEntity);
_uow.Register.Insert(Empinsert);
_uow.Save(); //this line shows error
return false;
}
}
}
Unit of Work:
using DataAccess.Repository;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DataAccess.UoW
{
public class Unit
{
private guruEntities _context = null;
private Repository<Table_1> _register;
public Unit()
{
_context = new guruEntities();
}
public Repository<Table_1> Register
{
get
{
if (this._register == null)
this._register = new Repository<Table_1>(_context);
return _register;
}
}
}
}
And this is the error I get :
C# 'Unit' does not contain a definition for 'Save' and no accessible extension method 'Save' accepting a first argument of type 'Unit' could be found (are you missing a using directive or an assembly reference?)

You have to add save method in your Unit Class like this
public void Save()
{
context.SaveChanges();
}
for better understand you can refer Unitofwork class from below link
https://learn.microsoft.com/en-us/aspnet/mvc/overview/older-versions/getting-started-with-ef-5-using-mvc-4/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application

Azure mobile service - accessing a table controller from another custom controller

I am trying to access a table using its controller from another controller method.
But when the method tries to call the table controller method I get an exception:
Exception=System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.WindowsAzure.Mobile.Service.TableController.....
I manage to access the table controller method from the web API and execute it successfully.
I tried the same thing with TodoItem given as an example by the initial mobile service.
After several publishes to the server trying to fix the issue the web API stopped working and I get this exception : An exception of type 'Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException' occurred in mscorlib.dll but was not handled in user code
Additional information: The request could not be completed. (Internal Server Error) I managed to solve it when I reopened a mobile service and database with the exact same code that didn't work.
Any tips ?
Here is my table controller created by the controller wizard:
using System.Linq;
using System.Threading.Tasks;
using System.Web.Http;
using System.Web.Http.Controllers;
using System.Web.Http.OData;
using Microsoft.WindowsAzure.Mobile.Service;
using FringProjectMobileService.DataObjects;
using FringProjectMobileService.Models;
namespace FringProjectMobileService.Controllers
{
public class StorageItemController : TableController<StorageItem>
{
protected override void Initialize(HttpControllerContext controllerContext)
{
base.Initialize(controllerContext);
FringProjectMobileServiceContext context = new FringProjectMobileServiceContext();
DomainManager = new EntityDomainManager<StorageItem>(context, Request, Services);
}
// GET tables/StorageItem
public IQueryable<StorageItem> GetAllStorageItem()
{
return Query();
}
// GET tables/StorageItem/xxxxxxxxxx
public SingleResult<StorageItem> GetStorageItem(string id)
{
return Lookup(id);
}
// PATCH tables/StorageItem/xxxxxxxx
public Task<StorageItem> PatchStorageItem(string id, Delta<StorageItem> patch)
{
return UpdateAsync(id, patch);
}
// POST tables/StorageItem
public async Task<IHttpActionResult> PostStorageItem(StorageItem item)
{
StorageItem current = await InsertAsync(item);
return CreatedAtRoute("Tables", new { id = current.Id }, current);
}
// DELETE tables/StorageItem/xxxxxxxxxx
public Task DeleteStorageItem(string id)
{
return DeleteAsync(id);
}
}
}
Below the other controller code trying to access the method:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Microsoft.WindowsAzure.Mobile.Service;
namespace FringProjectMobileService.Controllers
{
public class ArduinoController : ApiController
{
public ApiServices Services { get; set; }
// GET api/Arduino
public string Get()
{
Services.Log.Info("Hello from custom controller!");
return "Hello";
}
public async void PostProcessTag(String id)
{
Microsoft.WindowsAzure.MobileServices.MobileServiceClient client = new Microsoft.WindowsAzure.MobileServices.MobileServiceClient("http://some-service.azure-mobile.net", "XXXXXXXXXXXXXXX");
Microsoft.WindowsAzure.MobileServices.IMobileServiceTable<DataObjects.StorageItem> storage_item_table = client.GetTable<DataObjects.StorageItem>();
await storage_item_table.ToEnumerableAsync();
}
}
}
I also tried a different implementation for the method :
public void PostProcessTag(String id)
{
StorageItemController table_controller = new StorageItemController();
IQueryable<DataObjects.StorageItem> item = table_controller.GetAllStorageItem();
}
The service context:
using System.Data.Entity;
using System.Data.Entity.ModelConfiguration.Conventions;
using System.Linq;
using Microsoft.WindowsAzure.Mobile.Service;
using Microsoft.WindowsAzure.Mobile.Service.Tables;
namespace FringProjectMobileService.Models
{
public class FringProjectMobileServiceContext : DbContext
{
// You can add custom code to this file. Changes will not be overwritten.
//
// If you want Entity Framework to alter your database
// automatically whenever you change your model schema, please use data migrations.
// For more information refer to the documentation:
// http://msdn.microsoft.com/en-us/data/jj591621.aspx
//
// To enable Entity Framework migrations in the cloud, please ensure that the
// service name, set by the 'MS_MobileServiceName' AppSettings in the local
// Web.config, is the same as the service name when hosted in Azure.
private const string connectionStringName = "Name=MS_TableConnectionString";
public FringProjectMobileServiceContext() : base(connectionStringName)
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
string schema = ServiceSettingsDictionary.GetSchemaName();
if (!string.IsNullOrEmpty(schema))
{
modelBuilder.HasDefaultSchema(schema);
}
modelBuilder.Conventions.Add(
new AttributeToColumnAnnotationConvention<TableColumnAttribute, string>(
"ServiceTableColumn", (property, attributes) => attributes.Single().ColumnType.ToString()));
}
public System.Data.Entity.DbSet<FringProjectMobileService.DataObjects.StorageItem> StorageItems { get; set; }
}
}

Google Drive "get_error not implemented" error

I'm trying to implement the use of Google Drive in my app but I seem to be getting the following error "Method 'get_Error' in type 'Google.Apis.Drive.v2.Data.FileList' from assembly 'Google.Apis.Drive.v2, Version=1.2.4647.29713, Culture=neutral, PublicKeyToken=null' does not have an implementation".

I'm guessing some of your assemblies are out of date. That error will occur when you have an assembly for example, lets say foo.dll (v1) and that assembly is being referenced by bar.dll (v2). A class in bar.dll is expecting something in to be present on a class in Foo and its not there. In your case, its the get accessor for a property called Error on the class FileList. Double check all your assemblies to make sure they are all at their most recent version (s).
