Recently I have been trying to enable Application Insights (AI) on my simple SPARQL query UI on ASP.NET Core 2.1, with reference to quick-start guide on Microsoft Docs. After completing the configuation and trying out the website locally, I believe everyting worked fine. Though the SLA guarantees the delay of telemetries should be under 2 hours, actually I can see the requests in my development environment on Azure dashboard in less than 10 minutes.

Try WikiClientLibrary on Xamarin Workbooks!
I’ve noticed that MS announced their first pre-release for Workbooks, which allows you to experiment with .NET Framework / .NET Core / Xamarin / WPF in a Jupyter-like fashion. It’s like an enhanced version of C# interactive window.
What is really an improvement, is that you can add reference to NuGet packages in a similar way as you are working with a full C# project, so it exhibit a chance for me to play with WikiClientLibrary. Hopefully, it might give Wiki contributors some convenience on automated edits, such as word-replacement in batch.
Security transparency & sandboxed AppDomains
[This article is still a WIP. Updates may follow.]
Recently I am working on a C# sandbox for C# code, and come across a lot of buggy situations. Here I am just trying to sort them out. Continue reading “Security transparency & sandboxed AppDomains”
If the parent process creates an anonymous pipe after the child one started up…
The newly-created pipe handles won’t be inherited to the child process. Continue reading “If the parent process creates an anonymous pipe after the child one started up…”
If resx localization doesn’t work on your .NET Core application…
Let’s say, you are writing .NET Core application in VS 2017. You have added the following resx resource files to your project
- Resources.resx (Let’s take it as en)
However, when running on a French OS, sometimes you may still get English text for
You might as well try Rebuilding the project.
Written a MediaWiki Client Library
This is a MediaWiki client library based on .NET PCL, targeting at .NET Framework 4.5, ASP.NET Core 1.0, Xamarin.iOS, and Xamarin.Android. The verified supported MediaWiki API version can be as low as MediaWiki 1.19 (Wikia). FYI, now Wikipedia is using MediaWiki 1.28.

Create albums in PowerPoint !
Recently I’ve programmed a tool that can automatically generate albums in PowerPoint. What you’re supposed to do is to prepare your photos, and write a script. When these materials are ready, just run this little application and you’ll get the presentation document.
Here’s a quite simple demo
Querying Network Status in .NET programming
Work with `My` namespace
We can use My.Computer.Network.IsAvailable in Visual Basic.NET to determine whether the network is connected. The definition of this property is:
'''********************************************************************** ''';IsAvailable ''' <summary> ''' Indicates whether or not the local machine is connected to an IP network. ''' </summary> ''' <value>True if connected, otherwise False</value> ''' <remarks></remarks> Public ReadOnly Property IsAvailable() As Boolean Get Return NetInfoAlias.NetworkInterface.GetIsNetworkAvailable() End Get End Property
It leads to the approach in C#. Continue reading “Querying Network Status in .NET programming”
Play with Linq.Expression
Suddenly Visual Basic 6.0 ……
Yesterday once more.
There’s virtually no way to debug into it…
So I had to use something like `Debug.Print`. Really had a hard time.
So I decided to implement XmlSerializer “again”
Reinventing the wheel T_T
ref = CXuesong/XSerializer/
Pull is welcomed T_T if you’d like to
Recently I’ve been considering the following problems:
When serializing using `XmlSerializer` to get more control on what the XML should look like,
- How to serialize members with type `Nullable<T>`, persisting it as XML attribute (rather than element)?
- How to serialize references, avoiding it persisted as multiple identical copies of one object?
- How to achieve the these two things above, without introducting public auxiliary properties?
(e.g. for case 1, an auxiliary property can be introduced to do the conversions between `Nullable<T>` and `string`, the latter of which can be persisted as XML attribute.)
It seems that case 2 can be solved using `DataContractSeriallizer`. However, `DataContractSeriallizer` generates Id by itself, and represent Id and its references with `z:Id` and`z:Ref`. As I’ve mentioned in previously (在 XmlSerializer 与 DataContractSerializer 之间抉择), `DataContractSeriallizer` is rather rigid when you want to control the appearance of XML tree it generates.
Then, how to solve these problems?
Maybe, I’ll reinvent the wheel.
