NET Standard. But there were a few tricky things like libraries for PDF generation or image processing. These have potential to be blockers to getting to a point where you can run cross-platform, so you may need to consider breaking out any legacy code that absolutely cannot be ported into a separate microservice that still runs on. NET Of course, many of your dependencies may be your own shared libraries.
We converted these to target. NET Core services and legacy. NET Framework services could both take dependencies on them. Third , move all business logic and database access code out into library classes that dual target.
NET and. This requires using thin controllers rather than thick controllers, where the controller's only job is to call maybe via a mediator into a request handler and then convert its response into the appropriate HTTP response object. Fourth , once you've reached this point, you can create a new ASP. NET Core 3. Then you need to recreate all your controllers and routes, as well as set up all your middleware e.
This part is a rewrite, but it's a much smaller scoped rewrite than would have been necessary if all the database access code had to change as well. Thanks to EF 6. Let me know in the comments if you've done a similar thing or if you have any other tips for making the migration go smoothly. I'm pleased to announce a new Pluralsight course - " Microservices Architecture: Executive Briefing ". This is a short 30 minute high-level overview of what a microservices architecture is, why you might want to use it, and some pointers on how to be successful with it.
It was also my first foray into live video recording. Unlike most Pluralsight courses, this one is mostly a video of me speaking apologies for making you look at my face! It was certainly a steep learning curve. I had to buy a fair bit of equipment including a new camera I went for the Canon EOS D and some video lights, and after several failed attempts I finally managed to get the desired level of image quality.
I'm certainly no expert, so I'm sure there's a lot of room for improvement but I'm pleased with how it turned out in the end. This course is aimed at executives and decision makers rather than at programmers, so I've kept things quite high level and focus more on the why than the specifics of how.
I have a couple of other course in the library Microservices Fundamentals and Building Microservices that are much developer-oriented if that's what you are looking for. In the course I try to answer seven simple questions. First, what are microservices? This question can be answered purely in terms of what it means from a software architecture perspective that microservices are small and autonomous , but it is also important to understand that microservices are a way to scale teams.
This point was excellently made by Brendan Burns recently in his talk at the recent. NET Focus on Microservices conference. I highly recommend you take some time to watch some of the sessions from that event. Second, what problems do microservices solve?
Again, this is not just scaling from a software perspective, but scaling your team so that many developers can worth together efficiently on the same overall product. HTML5 is a evolution of the web, not a revolution that will totally destroy the past. Hence, let's move forward a little bit gracefully. In my example above, I am using a flash mp3 player from PremiumBeat. If your browser doesn't suppport HTML5 but you have got flash plug-in, you probably don't want to miss the fun.
You can trigger a download with the HTML5 download attribute. That means the page and the file must share the same domain, subdomain, protocol HTTP vs. HTTPS , and port if specified. Exceptions are blob: and data: which always work , and file: which never works. If it is blank, the browser defaults to the file's name.

All of my users use Internet Explorer. Active Oldest Votes. Paul, I tried it and it works great in Mozilla and Opera. But unfortunately it's not working in IE 8 :. Is there any replacement for "Audio" object so can be supported by older IE browsers? Do I have to enable any features for that? How are the sounds encoded? IE9 only likes MP3.
