Twilio SMS 无法通过部署到 Web 服务器的 ASP.NET MVC C# web 工作（但在本地测试环境中工作正常）

Question

I had a very strange situation where SMS messages sent via Twilio were working when my team tested it in the local host ASP.NET MVC & C# testing environment (VS2022).

But the deployed version on the web server throws an initialization error and the SMS is never sent.

The code is in a static class called Common . After hours of attempts, I discovered (to my horror) that Twilio does not properly initialize from a static class when running on the web server. But it works fine in the local host test environment.

My solution was to change the Common class from a static class to a dynamic public IDisposable class and remove all references to 'static'. How that is done is so fundamental and verbose that I don't feel the need to explain it.

I know, I know... why (the hell) was I using a static class in a webpage? Because I stole a bunch of working code from an old WinForms app and it was working just fine for everything else.

Here's how you call a dynamic IDisposable class called Common :

        Common thisCommon = new Common();
        thisCommon.Method();
        thisCommon.Dispose();

After this terrible experience, I decided to NEVER ever use static classes in C# / ASP.NET MVC web pages ever again. It's not reliable in all situations. And, to be frank, it probably was a terrible idea in the first place.

Answer 1

As I said above, you shouldn't be so lazy and use a static class in an MVC 5.0 C# web app environment. Make it a dynamic iDisposible class and things will work properly.
