@WuLex
i can understand anything。。

@markusschaber
Does anyone know good tools to model and generate state machines?
Something like UML StateChart editor, which then generates C# classes?
(Or does anyone know a better place to ask this question? :-) )
@WuLex Sorry, most of us don't speak chinese...

Hi guys, Is there any roadmap for http/2 implementation (client/server) on .net standard and .net core? I suppose there’s one for .net core 3.0, but couldn’t find anything for .net standard
Hirad Yazdanpanah
@hiradyazdan
@karelz ^
Karel Zikmund
@karelz
@hiradyazdan why do you need .NET Standard? Why is .NET Core 3.0 not enough?
Hirad Yazdanpanah
@hiradyazdan
@karelz well, I need a client implementation for Unity, I have found some non-official implementations, but was wondering if there’s any roadmap for .net standard in the future anyway
Karel Zikmund
@karelz
From that perspective it is unlikely, HTTP/2 relies heavily on our SocketsHttpHandler which won't work well on iOS and Android - they need native handlers there
so no plans today
Unity can choose to take SocketsHttpHandler from CoreFX I assume, but it is up to them / up to what they use
Hirad Yazdanpanah
@hiradyazdan
I see, thx, I try to track it down why SocketsHttpHandler not working well on mobile for Unity, afaik unity compiles to cpp for mobile anyway

anybody familliar with dotnet pack ?
trying to pack dll given by a vendor ... so we got managed and native dlls
I tried to create a nice csproj so that running dotnet pack would properly pack everything
i'm not sure what the folder structure but i attempted to get it like :
image.png
the csproj look like
<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <None Include="lib\netstandard2.0\ThirdPartDotNet.dll">
      <PackagePath>lib\netstandard2.0\ThirdPartDotNet.dll</PackagePath>
    </None>

    <None Include="runtime\win-x86\native\THIRDPARTNATIVE.dll">
      <PackagePath>runtime\win-x86\native\THIRDPARTNATIVE.dll</PackagePath>
    </None>
    <None Include="runtime\win-x86\lib\netstandard2.0\ThirdPartDotNet.dll">
      <PackagePath>runtime\win-x86\lib\netstandard2.0\ThirdPartDotNet.dll</PackagePath>
    </None>

    <None Include="runtime\win-x64\native\THIRDPARTNATIVE.dll">
      <PackagePath>runtime\win-x64\native\THIRDPARTNATIVE.dll</PackagePath>
    </None>
    <None Include="runtime\win-x64\lib\netstandard2.0\ThirdPartDotNet.dll">
      <PackagePath>runtime\win-x64\lib\netstandard2.0\ThirdPartDotNet.dll</PackagePath>
    </None>
  </ItemGroup>

</Project>
but the result is kinda disturbing

if anybody got an idea why it completly ignore the items from the runtime folder
if there's anybdy interested trying to make dotnet pack work
i attempted a "repro" here https://github.com/tebeco/PackageNativeLibAndWrapper/
TeBeCo
@tebeco
(there is a chance that dll in x86 and x64 are not respectivly x86 and x64 but i'll fix that later

Hi can someone help a beginner with winforms using the PieChart Example from Github? it works fine but when i try to put the pie in a winforms panel - it doesn't show. there is no error/exception. I have tried playing with the panel properties and form properties.

Given that IQueryable<T> extends IEnumerable<T>, that IQueryable<T> declares Where(Expression<Func<T, bool>>)) and IEnumerable<T> declares Where(Func<T, bool>), how does the C# compiler distinguish between both methods when using something like new List<int>().Where(x => x == 42) ?

Hi all, anyone worked with .Net Framework and Visio files? I would like to programatically add an image element via a console application in C#. Is there a doc/example I could reference? The flow is once a document is placed in a folder, I would like to add a watermark like status image at the bottom right. Thank you.

Hello. .NET, a developer platform for building apps, needs to have an editor provided as part of .NET release. VSCode is an excellent choice. VSCode would need to provide first class support for .NET.

Why dotnet publish do not copy wwwroot to output with -runtime linux-x64, but win10-x64 - is ok?
dotnet publish -c Release -o out -r linux-x64 --self-contained true /p:PublishSingleFile=true /p:PublishTrimmed=true /p:PublishReadyToRun=true
TeBeCo
@tebeco
is your csproj web sdk ? first line of the csproj itself
Artemov Ivan
@ZOXEXIVO
Is it Microsoft.NET.Sdk.Web (Blazor Server App template)
I change only runtime identifier to linux-x64 and wwwroot not copying
TeBeCo
@tebeco
got no idea out of this one, i suggest you to open an issue on blazor repo if it's specific to blazor SDK
also it's surprising that blazor that is a "client" tech has a wwwroot
blazor server side might be a bit tricky then
Artemov Ivan
@ZOXEXIVO
stop, of course - it's my bad
TeBeCo
@tebeco
?

@ZOXEXIVO
i just migrated my angular app and i have wwwroot in gitignore.
Local build works ok, but build on Linux server use git)

Hi everyone!
Quick question: is the Windows.Foundation.Collections namespace still closed source? Where would I report a bug or feature request?
Karel Zikmund
@karelz
@Marv51 yes, closed sourced. Report maybe through some Windows feedback channel? (no idea)
Marvin Rühe
@Marv51
@karelz Thank you!

Hello. Would appreciate any advice on how to improve the throughput performance of a gateway-like service with requests that have a lot of data. Currently simply copying HttpWebRequest stream to context.Request.Body (OWIN).
TeBeCo
@tebeco
Migrate to aspnetcore on dotnet core would be a huge throughput performance gain
Does that count ^^ ?
muzharab
@muzharab
Yes, I believe it does. So there is a big performance difference?
TeBeCo
@tebeco

Kind of a huge one based on the assumption that you don’t have a bottleneck in your code base
By that I mean that if what is slow is, for example, a hot path using explicit lock() it won’t save you

But it will be a rather great improuvment for both throughput and memory allocation (so less GC hit => less “freeze the world”)

But it means you’ll have to rewrite your app to be aspnetcore compliant
And your third part netstandard/netcore compliant
muzharab
@muzharab
ok. Yes, there will be some challenges with porting because of library-dependencies. Thank you very much for the suggestion.

We just upgraded our dev machines from VS 2017 to VS 2019. Now, during debugging, the "Tasks" View does not work anymore, showing the following message:

Viewing Task information for .NET Core 2.2 is not supported while the process is running. You can either re-target a newer version of the runtime, or view task information for minidumps of .NET Core 2.2.

Actually, the project is targeting .NET Core 2.1 (which is LTS version!), and one of the two affected machines has neither 2.2 SDK nor 2.2 runtime installed.

What's happening here, and how to fix it (except downgrading to VS 2017)?
