Visual Studio 2017 is here

Tomorrow is the launch day for Visual Studio 2017. This year marks also a 20th anniversary.Visual Studio 2017 launch event

Visual Studio 2017

If you are interested or a fan just go to where you can watch the live streaming of the whole event. There might be also a local event in your town so have a check at whether someone is hosting the event near you and go there. You will not only find out about Visual Studio but also meet great people there.

If you happen to live in Wrocław, we do also have a local event here that you can visit. Check the meetup page for more details. If you can’t attend, or there it’s already fully booked – don’t worry, it should be recorded.

My contribution to this event will be to present how Visual Studio was before it entered the .NET phase. I’ve started with the tools with the 6.0 version and to be honest, I had the mixed feelings about it.

We came from this…

Visual Studio 6.0

…to this

Visual Studio 2017

A lot has change along the way. Happy birthday Visual Studio!

We’ve already covered Vision and Speech API – now’s the turn for Language API.

This part consists the most features that we could try. We can spell check with Bing, use Language Understanding Intelligence Service (LUIS) for understanding the commands from the users, or analyse the text with Linguistic Analytics API. What is also available is Text Analysis (i.e. sentiment) or just simple a translator API. The last available service is Web Language Model based on data from the web.

Skipping the translator, as this is probably not very interesting service, let’s check what is…


LUIS or Language Understanding Intelligence Service offers the ability to add text understanding to our application without coding a bunch of if-statements. The actual page for the LUIS service is and there we need to create an account in order to start using the service. There we can provide examples of the phrases that LUIS should learn from and extract relevant information of the things we want to talk to it. If we just want to play with it, there’s a nice example on MS Cognitive Services website.

Text Analysis API

Another interesting services that located under the Language part of Microsoft Cognitive Services. It allows to extract useful information from the text.

Text Analysis API

It can detect the language, extract key phrases from the text and also provide information about sentiment. Currently works with language like English and Spanish. For Polish, it can only detect that the text is written in it.

The last described service is..

Web Language Model

Services that we can use there are ranging from detecting the spaces in a long string. So we can get “some long text without spaces and anything” from “somelongtextwithoutspacesandanything”.

Congitnive Services detecting the spaces

It allows also to calculate probabilities of words/phrases being put in a sentence together as well as  to get the percentage of two words/phrases are combined with each other. Finally we can use it to predict what is the best match for group of words that is commonly present.

If you are dealing with text – Microsoft Cognitive Services Language API might be handy to add additional layer of intelligence to your app. Have you used it already?

Microsoft Cognitive Services - Speech API

Apart from Vision API another interesting part of Cognitive Services is Speech API. Here we can use Bing Speech API to convert text to speech, custom speech API or Speaker Recognition API. Let’s look at the last one. Read More

Microsoft Cognitive Services - Vision API

Vision API allows us to get insights from images and videos. In this category we have services like: Computer Vision, Content Moderator as well as Emotion, Face and Video API.

Computer Vision

The most broad is Computer Vision. It allows to extract a set of features from images. We can get a general description of the image, tags with the information that image contains, general information about faces present in the image. It can also recognises celebrities. To enable that we need to put that into details parameter.

Vision API recognises Steven Seagal

To control what API returns, we can use VisualFeatures query string parameter.

Interesting values is Adult, which analyses and image whether it might be NSFW. If you get a lot of links of images which you don’t know whether should be displayed on work computer you might want to run it by Vision API and check adult section

There are parameters that values close to 1 might indicated that the content might not be suited for work. Quite a nice feature of Microsoft Vision API.


Faces API focus only on one element of the images – mainly recognising people’s faces that are present on images. If you remember a Nikon advertisements that presents it’s new Face priority focus – this is what you get from this feature.

But that’s not all. We get additional information about ears, nose, eyebrows are mouth.

Faces API in use


That’s one is simple – we get the person’s emotions on that picture. Pretty awesome.

Emotions API in use


This one allows us to get insights into the video providing features like face or motion detection, image stabilisation. It is also possible to use before mentioned features on the provided video. Navigate to and check the example located in the “Analyze in Near Real-Time” section. It. Is. Amazing.

Do you know what was the rant, a couple of months ago, about this picture?

Or do you wonder how that calculates (correctly or not) your age works? If you are interested in – the read on. Read More

Why my Visual Studio zoom is at 150%?

If you happen to see my Visual Studio at my normal day work you might notice that my font is big. Is my sight that bad? And it’s not that I’m sitting 10 meters from the screen. Not at all…
