Few days ago when I wanted to use SignalR in the project I installed Microsoft.AspNet.SignalR using Package Manager console.
Install-Package Microsoft.AspNet.SignalR
I found another simpler solution for the problem that does not require SignalR anymore in the project. I uninstalled the package:
Uninstall-Package Microsoft.AspNet.SignalR
After running above command, i did notice package Microsoft.AspNet.SignalR
was removed from package.config
file.
I assumed whatever changes installation of package was made into project, it would clean automatically with uninstall command.
However, a day after I saw some errors in console log.
WebSocket connection to 'ws://localhost:61135/signalr/reconnect?transport=webSockets&messageId=d-74CFF57F-B%2C0%7CF%2C0%7CD%2C0%7CG%2C1&clientProtocol=1.5&connectionToken=moGkKaoibXu6xg4srnQoGTdxp3axLXQ5h5guoaVYP25MgSKutfN8D%2FyQcJhXamlWjnAhBDIPMjWUEoM9W3%2BP6SQcoQ98jwuiV7lox%2BMNfgyx2x0FOlj6%2BO2PcQ%2Fl3WgwYsbQd7J%2FL1XFVe3yOvNuzw%3D%3D&connectionData=%5B%7B%22name%22%3A%22notificationhub%22%7D%5D&tid=4' failed: Error during WebSocket handshake: Unexpected response code: 502
I felt although I am not initializing the hub in JS anymore the hub initialization code is still running somewhere. I remove StartUp.cs that I added as part of adding SignalR. Ran the application and found this error on browser.
I then investigated what else is still left inside my code base and found SignalR did leave a lot of dependent packages and code files.
Comparing my package.config file, I have below packages result of install command:
+ <package id="Microsoft.AspNet.SignalR.Core" version="2.2.0"
targetFramework="net45" />
+ <package id="Microsoft.AspNet.SignalR.JS" version="2.2.0"
targetFramework="net45" />
+ <package id="Microsoft.AspNet.SignalR.SystemWeb" version="2.2.0"
targetFramework="net45" />
+ <package id="Microsoft.Owin" version="2.1.0" targetFramework="net45" />
+ <package id="Microsoft.Owin.Host.SystemWeb" version="2.1.0" targetFramework="net45" />
+ <package id="Microsoft.Owin.Security" version="2.1.0" targetFramework="net45" />
Question 1
Do I have to manually uninstall each one of these packages one by one? Any shortcut?
Question 2
There were js files as well in script folder even after uninstall, i had to manually remove it. Is this really required?
jquery.signalR-2.2.0.js
jquery.signalR-2.2.0.min.js
Is this the problem with SignalR package or I did something wrong to face this time wastage situation?
