Blazor.EventAggregator now works with Blazor 0.9. The library was first released back in February when Blazor was still (partly) called Razor Components and we were still using .cshtml-files. Blazor.EventAggegator 1.1.0 release updates the library to work with latest preview bits of Blazor.

For those not familiar with Blazor.EventAggregator, it is a lightweight Event Aggregator for Blazor. Event aggregator is used for indirect component to component communication. In event aggregator pattern you have message/event publishers and subscribers. In the case of Blazor, component can publish its events and other component(s) can react to those events.

Attach to dotnet.exe extension for Visual Studio 2017 & 2019 now has a new version 1.0.0.1. As the version number indicates, only a small thing has changed: The extension manifest had problems with its dependencies, causing issues when trying to install the extension to VS 2019 Preview.

The new version is now available for download from the project’s repository: https://github.com/mikoskinen/AttachToDotnet/tree/master/releases/1.0.0.1

Unfortunately the extension is still not available through the Visual Studio’s extension marketplace, but I hope to have it there in the following week.

Background

Just a quick recap and reasoning for the extension: There’s usually many dotnet.exe processes. Attaching Visual Studio’s debugger to the correct one can be hard. This extensions aims to solve the issue by displaying the actual .DLL of the dotnet.exe process.

Alias engine is a new MIT-licensed open source C# & .NET Standard based engine for creating aliases for your commands. It's inspired by the alias support which mIRC provides.

Example: Alias “ae” can be used to execute command “Alias Engine”.

The project can be found from GitHub and the engine is available through Nuget https://www.nuget.org/packages/AliasEngine/.

Background

What is an alias and what you can do with them? Aliases can be used to shorten commands. If your application provides a “help” command, you can provide a shorter alias “h” for running it.

Alias Engine can also be used to provide alias feature for the end user. Your application can provide a fixed set of commands like “help”, “show”, “create” and the user of your application can create aliases for executing the commands.

Features

Alias Engine supports these features:

  • Multi-Command aliases
  • Multi-Parameter aliases
  • Multi-Word parameters

Here’s a quick example of using the engine:

var converter =new AliasConverter(new InMemoryAliasStore(),new NullLogger<AliasConverter>());
converter.AddAlias("/x multiple return words");
converter.AddAlias("/j /join {0}");
...
[Test]
[TestCase("/x", ExpectedResult ="multiple return words")]
public string CanRunAlias(string alias)
{
var result = converter.Convert(alias);
return result[0];
}
...
[Test]
[TestCase("/j hello", ExpectedResult ="/join hello")]
public string CanRunAliasWithParameters(string alias)
{
var result = _converter.Convert(alias);
return result[0];
}

I’ve released a new open source extension for Visual Studio 2017&2019 which aims to make it easier to attach and to reattach the Visual Studio debugger to the correct dotnet.exe process:

With the default “Attach to process” –feature in Visual Studio it’s often hard to know what is the correct dotnet.exe to debug. Without the extension the visibility to dotnet.exe process is often this:

The extension aims to solve this issue by parsing the actual application from the process’ command line. In addition to displaying and attaching to a particular project, the extension provides “Reattach to dotnet.exe” command. This functionality works even if the process id changes (as it does when using dotnet watch).

Default shortcuts: 

  • Reattach: CTRL + Shift + Del
  • Attach: Shift + Del

Note: For now the extension has been mainly tested with ASP.NET Core 2.0 based applications. Later versions of ASP.NET Core and .NET Core may change things so it’s possible that the extension displays these processes incorrectly.

The extension is not yetavailable from Visual Studio Marketplace but I hope to see it there shortly. But you can download and install it from here: https://github.com/mikoskinen/AttachToDotnet/tree/master/releases/1.0.0.0

The source code for the extension is available through Github: https://github.com/mikoskinen/AttachToDotnet
