"Dictioary clear() results in mismatched count." line 909.

Hi,
I´ve downloaded the latest version, [email protected].
And the compiler is raising that exception:
"Error TS1039 Initializers are not allowed in ambient contexts."
On file typescript-dotnet-amd\System\ExceptionType.d.ts.
I'm using typescript 2.1.4.
Do you know why this is happening?
Thanks!

Hi,
I just found your TypeScript library as i started researching typescript + .net mapping tools. Its really great. I wondering how difficult would be to add something like JS Guid support. You have a Datetime support already and adding support for GUID would allow to use your library with Sql mappers as primary key is GUID most the time. My typescript knowledge is just beginners level and it would be great if the pro like you would add directly to this library. What do you think?

console.log(Enumerable.from([1,2,3,4,5,6]).skip(1).takeExceptLast(2).toArray());

How about a TryCast method? Could be useful with ajax and unknown types... Also, just wanted to say this project is awesome and mind boggling that the community hasn't migrated here yet.

XObject was just checked in at the level of which the .NET framework implements it.
https://github.com/electricessence/TypeScript.NET/blob/develop-%28System.Xml.Linq%29/System.Xml.Linq/XObject.ts

It uses EventDispatcher and a new class called EventHelper to manage changing and changed events.
Please review the XObject code since it will be a significant class for the rest of the System.Xml.Linq namespace.

It will be necessary to have something analogous to these static methods in order to ensure conversion is the same.

Here's some examples.
http://stackoverflow.com/questions/2534803/string-format-in-javascript

Let's make sure to allow for IFormatProviders for localization.

Start the Threading namespace by adding the Task class.
This will ultimately be super useful for managing deferred timeouts.
After reviewing other defer utilities and how timeouts are managed/cancelled/disposed, etc, this really needs to happen.

Sample code for reproduction:

                var sorted = Linq.Enumerable.fromArray<ICustomer>(customers)
                    .orderBy(c => c.Name)
                    .toArray();

Let ICustomer be some Interface with a Name-property.
Then look at "sorted"'s values. Most of them are "undefined" :-(

Hi,

I'm following the steps that you had shown in the video. However I'm using VS2015 instead of WebPack. I'm trying to use the library in a console nodejs project in VS2015. I've installed the library using npm. However it is giving me below error.

Error TS2307 Cannot find module 'typescript-dotnet-umd/dist/es6/System.Linq/Linq'.

Could you please help me out here in resolving the error?

Also can you please update the documentation with examples from JSON and other functions such as where, find, filter etc?

something like get isUpdating():boolean

Proposing:

orderUsing(comparer);
orderUsingReverse(comparer);

Constraint of a type parameter cannot reference any type parameter from the same type parameter list.

I'm getting this error in Visual Studio for ILinkedNodeList, ILinkedNode and assertValidDetached.

I fixed it by replacing "TNode" with "any":

interface ILinkedNodeList<TNode extends ILinkedNode<TNode>>
interface ILinkedNodeList<TNode extends ILinkedNode<any>>

Any other solutions or should I create a PR?

Visual Studio 2015, Update 1
TypeScript 1.7.6.0

Really like if this lib can be managed through bower packager infra

System/Compart.ts, the CompareResult enum is using a bitwise operator for each value. These operators seem unnecessary because you have a literal number oring against a literal zero. I was just curious as to why the author decided to do this.

When Webstorm supports the syntax.

https://github.com/electricessence/TypeScript.NET/blob/master/source/System/Time/DateTime.ts#L271

This is such a pain. I have to use different utilities to ensure the output matches what WebStorm does even when pointing to the lib. :(

Need to have this fixed as it is interfering with other steps like noEmitHelpers.

I'm starting a new project and would like to include TypeScript.NET.

What's the minimal setup needed to use it? The NuGet package installed source and dist folders. I would like to just have it sit under Scripts in a single folder.
What things do I have to delete and move to use the full library with a minimal number of files?

Currently groupBy and partition are over-engineered to have an element selector that complicates type inference.

Hi,

For example, i have an array like that:

var numbersArray = [1, 2, 3, 5, 6];
var myEnumerable = Enumerable.from(numberArray);
function total(): number {
return myEnumerable.sum();
}

numberArray.push(7);

In my application i'm using angular and binding the total result in the view.
Is possible whenever the numbersArray suffer any modification to be updated in the view?

I'm using Resharper 2016.2.2 and for unknown reason after added the typescript.net in my project the Visual Studio crash.
Anyone else is having the same issue? Is that a known bug?
The only temporally solution for that is to disable the Resharper.

This isn't urgent, but as the library grows, it could be seriously helpful.

Hi,

tried to port some logging helper from c#/java to typescript. The class EnterExitLogger is disposable and logs function entry (constructor) and exit (dispose).

The following usage works as expected:
protected usingTester() { var logger; using(logger = new EnterExitLogger(log, Log.Level.DEBUG, 'usingTester'), () => { return 1234; }); }

But when I have a function returning a value, I get a typescript error:
protected usingTesterReturn(): number { var logger; using(logger = new EnterExitLogger(log, Log.Level.DEBUG, 'usingTesterReturn'), () => { return 1234; }); }

Error: A function whose declared type is neither 'void' nor 'any' must return a value.

Do you have any idea how to handle this issue?

Regards,
Walter

"A JavaScript Friendly .NET Based Library Ported to TypeScript"

Implies that its a port of an already existing "Javascript-Friendly .NET Based library" to TypeScript.

a) If the library IS a port to TypeScript of an existing "JavaScript Friendly .NET Based library" the name of this library should be mentioned in the description and be read as "A TypeScript port of ${LibraryName}"

b) If the library IS NOT a port of an existing "JavaScript Friendly .NET Based library", but a port of .NET to TypeScript the description should be something like "A TypeScript port of .NET".

Steps to reproduce.

Create a folder structure like this(the + signal is just to illustrate the folder level:

+ testbug
++ build
++ src
+++ Person.ts
++ tsconfig.json

Have the following config on tsconfig.json:

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "sourceMap": true,
        "sourceRoot": "./src",
        "moduleResolution": "node",
        "outDir": "./build"
    },
    "exclude": [
        "node_modules",
        "build"
    ]
}

And the following src/Person.ts:

console.log('something');

Save everything and build the project (VSCode or tsc command line). Note that output files are dropped correctly to build/ folder.

Now, npm install typescript-dotnet --save and npm update --save.

Change the content of src/Person.ts to:

import List from "typescript-dotnet/dist/commonjs/System/Collections/List"

export class Person
{
    Name:string;
    Age:number;
}

Delete the content of the build/ folder.
Save all and now build the project again.

Notice that the output files are dropped into build/src/ instead of the src/ root folder.

The expected behavior is that the files got dropped on build/ while they are sent to the build/src. To confirm that the problem is with this module, comment the firs line (import List from....), clear the build directory and build again. You will see that the files are now again dropped correctly.

What can we do to workaround it?

Thanks for the great work on the project.

Best regards,
Gutemberg

Hi, Does this library come with declaration files? If not, then how are we supposed to use it?

Found this today and it seems to have the potential to replace my homegrown pseudo-collections :)
Thanks a lot for your work!

Two remarks:

• I think the Collections + LINQ part is the most important one, please make sure it is rock solid and complete before moving over to other .NET classes
• Please consider offering this as NuGet package, I've gotten addicted to it and can't add libs on my own anymore ;)

would like to see system.Xml.Linq in the awesome library.
maybe this code can be integrated:
http://ltxmljs.codeplex.com/

Shouldn't all the compiled TypeScript files reside on dist?

Docs will be out of date until this is fixed.

I notice that the method names are using the Javascript convention of a lower-case first character, whereas the .NET convention is upper case. If the purpose here is to generate a compatible library for porting C# to Typescript, why put the user through the tedious process of changing the first letter of every method call? If the purpose is to provide a familiar interface for people who already know C# and the .NET libraries, why diverge from the familiar interface?

For example, look at the Dictionary implementation.

I installed the Nuget package TypeScript.NET.Library into my project. When I try to build, it is looking for a node.ts file. There are 4 *.d.ts in the node package.

1. What version of the node.ts file am I supposed to load?
2. Please make this a dependency of the Nuget Package.

Thanks

Is simply a super useful feature to display time in a formatted string.

Also in addition to "sum" add "product".

WebStorm isn't recognizing the AMD signature. Not sure why.

Hello, first of all i want to thank you for this great piece of work :)
I'm using this in one of my current projects in a playground and found a bug? while playing around. I'm not sure if it really is a bug, it might be also just a misunderstanding of how this library works.

var objArray = [
    { Name: "John", Id: 0, Salary: 1300.00, Company: "Microsoft" },
    { Name: "Peter", Id: 1, Salary: 4800.50, Company: "Microsoft" },
    { Name: "Sandra", Id: 2, Salary: 999.99, Company: "Microsoft" },
    { Name: "Me", Id: 3, Salary: 1000000000.00, Company: "Hell Corp." }
];
var groups = Linq.from(objArray).groupBy(x => x.Company, x => x);
var companies = groups.select(x => x.key).toArray();
console.log('Companies: ' + companies.toString());

This works fine. But if i want to access the individual groups it doesn't work as i expected.

groups.forEach(x =>
{
    var enumerable = new Linq.Enumerable(x.getEnumerator);
    console.log(x.key + ': ' + enumerable.sum(x => x.Salary).toLocaleString())
});

This code in the second line enumerable.sum() causes this error: "too much recursion". It looks like all methods throw this error.
But this works:

groups.forEach(x =>
{
    var sum = 0;
    var enumerator = x.getEnumerator();
    while (enumerator.moveNext()) {
        sum += enumerator.current.Salary;
    }
    console.log(x.key + ': ' + sum.toLocaleString())
});

I'm coming from C# and the first option looks more intuitive. If this is is working as intended this might be a good thing to change? :)

Edit: I tested this in Firefox 41.0.2
In Chrome 46 i get this error: "Uncaught RangeError: Maximum call stack size exceeded"

I can't build my project.
I'm attaching here an image showing the errors.
https://portalvhdsdtx1sqp9m14cf.blob.core.windows.net/vhds/TypeScriptNet_Errors.jpg

It looks like it's missing some files.

Hi @electricessence. I just created some performance test and it's awsome! You can look on this http://jsperf.com/lodash-lazy-lx/4

Can you please provide a sample on how to use the event classes? There are no tests in the repo that can provide a reference point.

Thanks

marc

The DateTime class could be very helpful as a replacement or upgrade to the current javascript Date object.

I could really use some help and feedback with the other namespaces.
System
System.Collections
System.Linq

I would love to hear any helpful criticism about their implementation and flagging any missing classes that you really think need to be included.
