C# 11 is the next version of C# coming in .NET 7, and it is introducing a warning wave that issues a warning when a type is declared with all lower-case letters. This is being done so that in the future the language can begin moving away from conditional keywords and instead use full on keywords instead. The warning is alerting customers to types that may become keywords in future versions.
db.Entry(message).State = EntityState.Added; db.SaveChanges();
try
{
// Your code...
// Could also be before try if you know the exception occurs in SaveChanges
context.SaveChanges();
}
catch (DbEntityValidationException e)
{
foreach (var eve in e.EntityValidationErrors)
{
Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
eve.Entry.Entity.GetType().Name, eve.Entry.State);
foreach (var ve in eve.ValidationErrors)
{
Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"",
ve.PropertyName, ve.ErrorMessage);
}
}
throw;
} What is concurrent programing? Simply described, it’s when you are doing more than one thing at the same time. Not to be confused with parallelism, concurrency is when multiple sequences of operations are run in overlapping periods of time. In the realm of programming, concurrency is a pretty complex subject. Dealing with constructs such as threads and locks and avoiding issues like race conditions and deadlocks can be quite cumbersome, making concurrent programs difficult to write. Through concurrency, programs can be designed as independent processes working together in a specific composition. Such a structure may or may not be made parallel; however, achieving such a structure in your program offers numerous advantages.

چطور کارهامون رو به صورت Async انجام بدیم با استفاده از Channel و HostedService
I hope you are satisfied with this tutorial. In these two articles, we tried to tell you the ways in which we can do things with maximum efficiency in full Async, without worrying about the completion of the Request and the Disposal of our service. These have always been among the concerns of various programmers. And always using inefficient methods such as not leaving the word await
When you publish your Blazor Wasm app, this package pre-renders and saves the app as static HTML files in your public folder.
This post provides a simple IValueConverter implementation that makes use of the framework type converters in order to convert between a large range of source / target types. This converter can be used both within bindings and in code-behind to give more concise property setters.
