I coded it in the assumption that asynchronous and parallel processing would be the same Asynchronous processing and parallel processing are quite different. If you don’t understand the difference, I think you should first read more about it (for example what is the relation between Asynchronous and parallel programming in c#?). Now, what you want … Read more
Yes, you can, exactly as you could use LINQ and .NET 2, as you said. I use the following in a .NET 4.0 project with the VS2012 compiler with success: namespace System.Runtime.CompilerServices { [AttributeUsage(AttributeTargets.Parameter, AllowMultiple = false, Inherited = true)] public sealed class CallerMemberNameAttribute : Attribute { } } Be very careful that everyone on … Read more
Looks like you are using the EF5 EntityFramework.dll but then running with .NET 4 installed instead of .NET 4.5. If you are intending to target .NET 4.5, then make sure that .NET 4.5 is installed on the machine on which you are running the code. VS11 installs .NET 4.5 for you, but you can also … Read more
Unfortunately not. There is no support within the .Net Framework 4.5 for password protected zip files. In this case you have to switch to one of the well known 3rd party libraries.
There are probably several reasons. Here are some: Huge backwards compatibility problems How would you write the definition of ICollection<T>? This looks natural: interface ICollection<T> : IReadOnlyCollection<T> { int Count { get; } } But it has a problem, because IReadOnlyCollection<T> also declares a Count property (the compiler will issue a warning here). Apart from … Read more
This can be done by taking advantage of the fact that your types and the SignalR types are in different assemblies. The idea is to create a JsonConverter that applies to all types from your assemblies. When a type from one of your assemblies is first encountered in the object graph (possibly as the root … Read more
Allocations >= 85 KB go onto the LOH. Compacting the LOH is not bad — it’s just that LOH fragmentation isn’t something the great majority of apps need to worry about, so for them it’s not worth the expense of compacting. Fragmentation occurs when you allocate several large objects and they all get taken from … Read more
DefaultSpatialServices in Entity Framework are using SqlGeography and SqlGeometry types as backing types. These two types live in Microsoft.SqlServer.Types.dll assembly that is not part of the .NET Framework. The exception is thrown when EF cannot find these types (the exception could be more helpful…). When you install Visual Studio it will install localdb on your … Read more
Most of these kind of questions can be answered by looking at the CLR source code as available through the SSCLI20 distribution. It is getting pretty dated by now. It is .NET 2.0 vintage, but a lot of the core CLR features haven’t changed much. The source code file you want to look at is … Read more
Here are my propositions: If you are able to add duplicate table to database then here is a solution. You have your table1 and table2 (Copy of table1). When you inserting new records to table1, you can compare them with existing records in your table2 and thus find new records. After comparing you should add … Read more
