Let's discuss where VB is going and interact with some of those that are making it happen!
Still getting used to gitter myself; so want to make sure that everyone is aware that there are several "rooms" related to VB.NET: https://gitter.im/VB-NET to see the full list. Please be sure to check out and join the other rooms you might be interested in.
Are there any plans to add VB.NET to ASP.NET Core 3.0 in the near future? I’m not talking about vbhtml or Web Pages, but creating new ASP.NET Core and Web API VB.NET projects using VB.NET for the code behind files. I would argue this is the biggest show stopper for Web Apps VB.NET developers trying to move to new technologies like .Net Core (and yes I know you can create console apps and class libraries using VB.NET).
You can do this today. There just aren't any templates, because the whole story is a bit complex. Much of that complexity is on the client side. Here's a link: https://devblogs.microsoft.com/vbteam/combining-angular-visual-basic-and-net-core-for-developing-modern-web-apps/ If someone wants to put a template together on this, I'm happy to get it publicize it and work on a good OSS location for it (which might be in ASP.NET)
Hi Kathleen, thank you for the info. I did read the blog post and downloaded the project. What makes it a little confusing to me is that the Web API code is mixed up with an Angular project. Do you know if there are any examples like this one but with the VB.NET Web API project separated from the SPA client project? I would also be very interested on seeing something similar but with a Blazor project. Thanks!
@MarceloJGaray I'm in the process of trying to wrap my head around Blazor as well; unfortunately, I really haven't found very many examples and it appears that a lot of the #Blazor (client side) stuff is a little behind the release of VS2019. There is a ton of converstation taking place in the https://gitter.im/aspnet/Blazor; so much so that I've kind of had to stop monitoring it due to being too busy with other commitments. However, just spending a few days monitoring it was very informative and there seems to be a lot of great people working on the project. In the end, I too would like to see some really solid samples around Blazor; if after getting my head wrapped around all this, I might put something together if someone else doesn't get to it first. (It's kind of foreign to me since I'm primarily a native client dev... where web development is done out of necessity, not by choice. ;-) )
One of the folks working on Visual Studio asked me the following, and I wanted to get other people's opinion. Thoughts?
I’m working on a “Target-typed completion” feature where the user can reduce the completion list down to only items of the type expected at a given location (or implicitly convertible types).
For completion in C#, see the first gif in dotnet/roslyn#34655
There would normally be tons more items in the list, but the user has clicked the “Target type match” filter at the bottom of the completion popup (left/right arrows in this screenshot), so the list has removed everything except these symbols which are actually valid at that location.
For completion in Visual Basic, I’ve gone and done the same experiment and I get a list with over 100 extra symbols, all from the Microsoft.VisualBasic assembly. While technically valid at a location expecting an Integer, these extra items make it hard to find the symbols that were easily discovered in C#.
So I think the questions are:
- Should we be blocking some or all of these symbols from showing up?
- If so, what heuristics should it be based on? Belonging to Microsoft.VisualBasic? Some other heuristic (or combination of heuristics)?
Please let me know what you think. 😊
Not exactly language.
(And, in VB, the line between UI Tools and Language is very blurred. ;-) )
Ah... gotcha... all of the "helper" variables (vbNNN). Is there the ability to have it be "just my stuff"? Where it would only contain things that are clearly part of the active source (solution) and include elements that are clearly api specific (as in the animated example you pointed to)?
Ignoring the VB runtime members might be good.
But like, I've recently come to appreciate that I never want to see anything in the list related to LINQ. I know there's a Where and a Select and like 50 other things around and I don't care to see them. Kinda miss Common & All. The IntelliSense doesn't need to be driven by the Option Strict setting at all, but you may want to look at only giving symbols with a Widening conversion, particularly widening reference conversions for complex times and maybe even identity conversions for the primitive value types. If it comes up.
I have been playing with 16.1 preview 3 and Comment after Line Continuation works as expected in .NET SDK projects but not in the IDE of a test project. Programmatically is works everywhere. Formatting is very strange in the IDE. I hate to complain because the ability to put comments virtually anywhere really aids in documentation. Identical programs after entered in VS IDE

@KathleenDollard The enabling issues were reported but not under Roslyn.
I had a wierd "repeat key" issue in VS19 occur last night in my live-stream; I had a writeline using a literal string that was about 40 characters long. I duplicated this line and set out to replace all the characters with a literal string containing nothing but spaces. When I toggled the insert key and then held down the spacebar... it worked for the about the first 10 characters and then randomly started skipping existing characters placing spaces randomly for the rest of the string. Anyone else ever see something like this?
Hi Marcelo, you may want to follow this thread. It's received quite a bit of traffic lately and in it, @KathleenDollard has promised a RoadMap update soon.

Hi folks, this (https://stackoverflow.com/questions/60021378/calling-constructor-from-shared-method-c-to-vb-net/) got me wondering: Would it be a good idea for the
Call statement to allow for "naked" object creation expressions?
