Dynamically enum's
My proposition is to make a dynamicaly defined enums, or possibility to set enums integer value dynamically.
Example:
I have document status in many customer systems.
In one of them I have statuses represented as enum:Created=1,
InRealisation=2,
Closed=3In other one i have:
Created=31,
InRealisation=33,
Closed=35but i want to get this id statuses from database, and assign them to existing enum. But now its impossible.

Inline deconstructed variable
It would be nice if I can inline deconstructed variables.
Example:
Current code:
var (username, password) = smtpCredProvider.GetCredentials();return new SmtpClient(opts.SMTPAddress, opts.SMTPPort)
{
EnableSsl = opts.SMTPUseSSL,
Credentials = new NetworkCredential(username, password)
};Expected code:
return new SmtpClient(opts.SMTPAddress, opts.SMTPPort)
{
EnableSsl = opts.SMTPUseSSL,
Credentials = new NetworkCredential(smtpCredProvider.GetCredentials())

Make C# local functions stand out in the editor
C# local functions is a nice feature that I like to use. But I find it difficult to visually identify such a function within a method. I would be nice to make them stand-out, using a different background, a border, or a left bar...

Add methods to clone an object tree or a part of it
Creating objects similar to others already existing is a common pattern that requires a lot of typing and bore just to map the properties of one into the other.
There should exist an extension method on the "object" object that could allow to create an object just cloning another one, with it's entere tree, or even better, until a determinate level of depth.0 votes -
"throw return" pattern as alternative to "async-await"
What I think would be a nice addition to C# would be recognize return as a special keyword of throw, so that you can completely unwind the stack upto the point where UI entered and return a value without raising an exception. This would allow a user to start an async task, add a few continuations to this task, then "throw return" back to the top of the stack to the UI...without using the async keyword at all. Example:
void XYZ_Click(…) {
if (DeeplyNestedFunction() == 1) {
...
}
else {
...
}
}int DeeplyNestedFunction() {
if (...) { …0 votes -
c#
Na minha opinião acho que seria melhor quando nos instalamos uma referencia uma .dll quando instalar ou executar o programa em outro
computador que não tenha o git hub ou algo que precise ser instalado para o programa funcionar invés de aparecer uma mensagem de erro direcionar com link para instalar o que falta o computador ficaria mais fácil de descobrir o que necessita para o programa funcionar corretamente em outro computador sou iniciante ainda e as mensagens de erro que aparecem no computador novo a ser executado nao são muito claras para mim.

Allow user to modify HTTP Accept and User Agent headers when using UriImageSource with caching
This is regarding using the compiler for Xamarin Cross-development in C#. For me to use avail myself of the downloaded image caching (UriImageSource) from the site I frequently download images, I would need to modify 2 HTTP header fields : User Agent and Accept. The header fields both have static information either identifying the app/Version and the acceptable returned data format. It would be very useful to allow the program to request these changes prior to the page appearing.

Customize icons in the Class View / Object Browser
Right now there's basically three icons in the Class View/Object Browser: the Blue Icon, the Purple Icon, and the Beige Icon. ^^
Well, it's true that when you look closer, you can notice some differences in the shape. The enum icon shape is different from the class icon one or from the folder icon one. However, you need to look closer to see it. It's not something that strikes you in a quick look, and that makes navigating those views less useful.
I would say that a good usability test would be to blur the icons, and yet to be…

Shortcut for creating tasks
Map this:
static Task MethodAsync() {
Task A = new Task(() => {
Console.WriteLine("A:begin");
for (int i=0; i < 10000; i++) {
Console.WriteLine("A:{0}", i);
}
Console.WriteLine("A:end");
doneA = true;
});
A.Start();
return A;
}Into this:
static TaskNew MethodAsync() {
Console.WriteLine("A:begin");
for (int i=0; i < 10000; i++) {
Console.WriteLine("A:{0}", i);
}
Console.WriteLine("A:end");
doneA = true;

Create a case expression
Add an expression syntax of the type:
var a = <select symbol> (expression)
{
<case symbol> <constant>: <expression>;
<case symbol> <constant>: <expression>;
}
Where a is assigned the expression result associated selected case. Of course every case expression would need to evaluate to the same type.I believe this syntax would be more elegant than:
int a;
select (b)
{
case "One":
a = 1;
break;
case "Two":
a = 2;
break;

Generic class type inference
Implement what's known as "The Diamond" in Java:
Box<Integer> integerBox = new Box<>();
Replace the type arguments required to invoke the constructor of a generic class with an empty set of type arguments (<>) as long as the compiler can determine, or infer, the type arguments from the context.

StringAssert.Equals should throw an exception just like Assert.Equals.
Right now it resolves to Object.Equals. However it looks a lot like string.Equals, which compares strings instead of identities.
Of course i got this when reading the manual, but it would still prevent confusion to make StringAssert.Equals behave like Assert.Equals instead of like Object.Equals.1 vote -
abstract inhertaible enums
Example;
public abstract enum AnimalType; //acts as a Base Class & interface
public enum CatType : AnimalType
{
Burmese,
Siamese,
Tabby,
...
}public enum DogType : AnimalType
{
Alsatian,
Beagle,
...
}Then use this Abstract enum as a Generic Type Constraint.
This then allows a family of enums to be created and avoids use of non-matching enums.
e.g.
public abstract class BaseClass<TAnimalEnum>
where TAnimalEnum : AnimalEnum
{
// do animal stuff
}then
public class CatClass : BaseClass<CatEnum>
{
// do cat stuff
...

Type safety in actions defined using lambda functions
There's a small problem when it comes to actions defined through lambda functions. I'm showing it in the screencap.
Let's say we have two methods: HellowWorld(), which returns a string, and DoNothing(), which doesn't return anything. There's no type safety problems when we use them through anonymous methods: Actions only accept anonymous methods that doesn't return any a value, while Func<string> only accept anonymous methods that return a string.
Now let's use lambda functions. No problem here with Func<string>: when the lambda function doesn't return a string, it shows an error, which it's OK.
The problem appears when you declare…

Add the ability to convert the use of "var" to the expanded declaration:
Add the ability to convert the use of "var" to the expanded declaration:
var i = 5;
hovering over i, intellisense tells us this is an int. Please add the ability to convert the "var" to it's expanded declared type (i.e int in this example).

Automatic string null coallesce with if
Rather than
if (str != null) { ... }
simply:
if (str) { ... }
Like C++

Add the "isnt" keyword
Simple suggestion, please add a new keyword: "isnt"
This would make code clearer and more readable. So rather than
if (!(myObject is ClassType)) { ... }
you would write
if (myObject isnt ClassType) { ... }
Looks clearer and provides a positive match rather than a negative match.

LINQ to SQL: Error Reporting Via Generated SQL With 0 = 1 Clause
LINQ to SQL error reporting is currently implemented by generating random SQL with a clause 0 = 1 (usually in a WHERE statement.)
My understanding is this typically happens when there's an out of sync between the definition of a class in LINQ vs the actual entity in SQL.I believe Microsoft's intentions were to return no results in this case, but the following issues arise by this implementation:
1) This is unintuitive to the developer, since generally no actual error occurs, just a change in the results being returned. The change in results being returned, could coincidentally be the…
