![]() ![]() The words belong solely to the blog owner at Sanity Free Coding. I'm reproducing the content of the article here for posterity. That makes me worry that eventually it might disappear, and with it, the advocated solution. UPDATEĪs of, the article I linked to above is still active, but the blog hasn't been updated in a while. That's a very nice touch that the other Mutex solutions described here do not address. Second, the article shows how to bring the existing instance of the application to the foreground when the user tries to start another instance. But as it is, I do not use the Microsoft.VisualBasic assembly, and I'd rather not add an unnecessary dependency to my project. If my project already had a dependency on that assembly, I would probably advocate using the approach shown in another answer. The approach described by the article is advantageous for two reasons.įirst, it does not require a dependency on the Microsoft.VisualBasic assembly. Here’s an example of the results:Īs you can see it is very easy to create a data access layer with SQLite as the database.Here is a very good article regarding the Mutex solution. The Web Api can then be tested using Fiddler. The Entity SQLite DbProviderFactories is defined in the application config file. If (type.GetCustomAttributes(typeof(T), true).Length > 0) Public static IEnumerable GetTypesWithCustomAttribute( Assembly assemblies)įoreach (Type type in assembly.GetTypes()) Reflection is used to search for the attributes. UnityHelpers.GetTypesWithCustomAttribute(myAssemblies),Ĭontainer.RegisterType(typeof(AnimalContext)) Var myAssemblies = ().Where(a => a.FullName.StartsWith("AnimalMarket")).ToArray() Public static void RegisterTypes(IUnit圜ontainer container) The AnimalContext is registered as a transient type. In this example attributes are used to define the different classes which are to be created and its defined lifecycle singleton = LifecycleSingletonAttribute and transient = LifecycleTransientAttribute. Protected virtual void Dispose(bool disposing) Return from a in _context.EventDataValues Return GetAnimalTypes().FirstOrDefault(a => a.Id.Equals(LambId)) Return GetAnimalTypes().FirstOrDefault(a => a.Id.Equals(PigId)) Return GetAnimalTypes().FirstOrDefault(a => a.Id.Equals(CalfId)) ![]() Return from a in _context.AnimalTypes select a Public EventDataRepository(AnimalContext context) Public class EventDataRepository : IEventDataRepository Public interface IEventDataRepository : IDisposable This needs to be disposed, so the IDisposable is also implemented. The context is added using Unity and construction injection with a transient lifecycle. Database does not pluralize table names Protected override void OnModelCreating(DbModelBuilder modelBuilder) Public virtual ICollection EventDataValues In this example it is a very simple 1:n model with just 2 tables. UPDATE: A new version of SQLite 1.0.91.3 has been released (available in NuGet, Version now works with the latest version of Entity Framework 6.0.2).Īnd you also require Entity Framework version 6.0.2.Ī domain model can then be created. ![]() (At present the can only be got from or you have to build the src itself.) The required NuGet packages need to be added. sqlite file is added to the project and ‘copied if newer’ when built. ![]() "FixChange" DOUBLE NOT NULL DEFAULT (0.0) ,įOREIGN KEY () REFERENCES ()Īpplication data can then be added directly using this tool: "EventDataId" INTEGER PRIMARY KEY NOT NULL , "Id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL UNIQUE , Updated all other NuGet packages as well.Ī SQLite database can be created using the Firefox addon. The xml app configuration needs to be changed due to this. UPDATE : Using the new SQLite version 1.0.93.0 now with the SQLite provider. Updated all other NuGet packages as well. UPDATE : Using the new SQLite version 1.0.91.3 now with the SQLite provider. The post continues on from Getting started, using SQLite with. In this post, a Data access layer is implemented using the repository pattern together with entity Framework 6 and SQLite as a database. ![]()
