I’m using Chrome from developer channel for a long time on my macOS.
Since August 14th, 2019, after an auto upgrade of the Chrome, it cannot be launched again. When starts, it shows a empty window with only 3 common color dots at the top left corner and then halt.
Tried rebooting and reinstalling, the problem cannot be fixed.
Currently, I turned it back to the stable channel, which works well.
Sorry that I cannot provide the version number of the affected version, which I cannot get without start it.
It says MSDN Magazine is ending soon.
Here is the MSDN Magazine collection hosted on my OneDrive. Password is “secretnest.info” without quotes.
All files are mainly downloaded from official site. The missing (2018 Jan / Connect) and not published (2019 June / July) are from my received emails (subscribed version). I will update the rest when they are published.
I attached some main tech involved at the file name.
Today, while writing an app use netfx 4.8 with MEF support based on System.ComponentModel.Composition 4.5 from nuget, a strange bug hit me.
Because I’m not treat MEF as essential, I’d like to write the main code in a project and create MEF wrap in another one like:
- In Project A: class Real : InterfaceA
- In Project B: class MEFWrap : Real, and marked with Export attribute.
Certainly, Project A is referenced by Project B. While building the solution, both dlls generated from Project A and Project B are placed in the output folder of Project B.
While trying to use MEF to load the class from Project B, the funny thing happened:
- If AssemblyCatalog is chosen to create the object, from the assembly object loaded by LoadFrom method, nothing is wrong, but
- If AggregateCatalog is used with all assemblies loaded from the folder (Project A and Project B) at the same time, an exception raised while calling ComposesParts:
The export InterfaceA is not assignable to type InterfaceA.
I don’t know why it’s happened but here are 2 ways to get avoid of it.
- Only load assembly Project B, not both of them, if it’s possible, when you know the name or name pattern while searching files, or
- Using AssemblyCatalog for each file, instead of using AggregateCatalog as a whole, will also works.
Adds support for low end bar code scanners, which work as a keyboard only. By using this library, you can receive code from multiple scanners with the scanner handle id or name (seeing demo on Github).

Today, I need to use an instance of synced version of HashSet in C#, aka, ConcurrentHashSet<T> in tech language.
First, I dig some in GitHub and NuGet. I found 2 solutions contains this solution, as they described. One has the exact name of ConcurrentHashSet, but it’s not implemented the ISet<T>. Another is a big set which contains this class with the name, which is written using ConcurrentDictionary<T>, with no ISet<T> implemented either.
Hmm, it seem that if I really need ISet<T> support, I have to do it myself. Let me create class inherited HashSet<T> to write some overridden methods and properties with lock… Wait a minute, only 3 methods from Object is allowed for overriding? Wtf.
If I cannot stand on the shoulders of HashSet<T>, let me dig the HashSet<T> first. Luckily, Microsoft released the source code of the entire dotNet framework. HashSet<T> is included as well. All I need to copy the whole code into mine and… Uhh? What’s the license of the file?
By asking a lawyer friend, I’m told that I MAY have right to use this code in my program but I’m NOT GRANTED to publish the ConcurrentHashSet<T> I wrote separately. That maybe the reason why I failed in the first step — Microsoft didn’t finish their job and don’t allow anyone to fix it for them.
By testing, some earlier published messages may be received by subscriber latterly than the messages followed.
If you want to use this model as channel, do be careful in dealing with message sequence.
Now all code of Remote Agency is published to Github. License is changed to MIT as well.
Check project page for details.
PS, another related project for networking transportation addon for Remote Agency is under constructing.
I wrote many solutions in Visual Studio. Some of them includes components, which intend to be published to Nuget.
Previously, I wrote these projects directly and publish them to Nuget. This is not a smooth way. Consider this: You have project A need to be published to Nuget. Project B, as well. Project C need to reference project A and B, and also need to be published to Nuget. Project D need to reference C for testing. Obviously, following Nuget standard, the Project C need to reference A by using Nuget Packages instead of the projects of A and B directly. But it seems that there is no called testing mode publishing in Nuget supported. There is no easy way to test your project before publishing to Nuget. Maybe you need to change the references in Project C and D repeatedly, switching mode between testing and publishing.
Recently, Shared Project support added to Visual Studio. Now I use a better way, IMHO, in developing such a solution mentioned above.
- Create a shared project for each project need to be published to Nuget.
- Put all codes into shared project instead of original one.
- Create a project for publishing to Nuget, reference the shared project related. — Project N
- Create a project for testing, reference the shared project related. — Project T
If your Nuget projects need more references which will be published to Nuget from this solution, add them from Nuget to the Project N, and add them as reference from their Project T to this Project T.
All Project Ns will only be used for publishing to Nuget. As well as all Project Ts will be used for testing. They share the same code but the different source for referencing.

Supported platform: NetFx 4.7.2
Sql Server 2017 (any edition) is required.
Add fraction support.
Using an instance built by default parameterless constructor will cause exception or miscalculation. To avoid this, always use parameter-based constructors. This will not be fixed due to consideration about running speed.
