Testing on windows, I get a few errors, logged as bugs://83396: .NET Core WPF app fails to buiild (No type converter, NRE). Might just be that the XAML needs to be adjusted from what .NET 4 used…

This is my test project: WPFApplication.zip (58.7 KB)

I tested last release and finally managed to build full project with Winforms and WPF on .net core 3.0 :slight_smile: But I had to change Settings to microsoft.windowsdesktop.app as main sdk/runtime and add Microsoft.NETCore.App.Ref as a package reference (to recognise WinForms). Then both frameworks compiled. Is that logical for You? I will test it more and let you know.

#14

Well, yes.

Ok are we mixing WPF and WinForms here? For WPF, which I tested with your last testcase, I had to drop Microsoft.NETCore.App.Ref from the references to make it build, because otherwise it got the wring WindowsBase.dll from that reference . I didn’'t test WinForms, and I;'m not sure if you’re supposed to be ab le to combine the two…

#15

Yes, mixing. Original project in .net 4.5 has both frameworks. New port to .net core also should have both. As I wrote earlier, this compiles now but I must check in VS 2019 if it works in design time and runtime.

#16

Ok, can you send m your fixed project for comparison?

#17

ConsoleApplication9_wpf_winforms.zip (134.0 KB)
This should be minimal test case. In my big project I see (Implicit) at WindowsDesktop reference. In this small project there is implicit notation. Does it matter ?

#18

EBuild will add one or more default packages, baed on the SDK type you selected, if they aren’t already referenced. if you have the reference in our project, it will show was normal; if you don’t, it will shows as “(Implicit)” to indicate that even though your project did not specifically (explicitly) specify it, it is still being referenced.

It should make no factual difference to what actually gets referenced, whether the package referent tis explicit or implicit.

#19

Update: looks like both packages are needed, but the dlls from Desktop need to take precedence over the ones from plain Core. What morons design this stuff? In any case, fixed for vNext.

#20

Thanks. Yes, a typical WIndows dll hell :frowning:

Purposely shipping an empty WindowsBase.dll in the core package is beyond dll hell, its malicious. WTF are they thinking…? :slight_smile:

Today I had internet offline for a few hours ( how to live with that :wink: ). I wanted to compile the project that we are testing but I got error :

Exception processing package reference Microsoft.WindowsDesktop.App.Ref:[3.0.0] : The operation has timed out

although the package is referenced implicit and exists on a local drive. Is that correct behaviour of Water?

#23

Hmm. Did you build this or another project that uses this package, before? of so, it should find it in the local cache. If not, the yes, int would have to go out get the package from NuGet servers.

I’ll try myself, here, what happens.

#24

Fwiw, new .NET Core app rebuilds for me clean, without internet connection:

Hmm, it looks as if the package is not in the cache (or for some reason it doesn’t get found in the cache)… This looks the same if you clean and build (not rebuild, rebuild actively ignores the cache), again?

#27

I made the clean build as you suggested.
Here are logs : build_online.txt (209.3 KB) build_offline.txt (12.2 KB)
In offline log file you will find error :

Exception processing package reference Microsoft.WindowsDesktop.App.Ref:[3.0.0] : The remote name could not be resolved: 'api.nuget.org'

But I have this package :

that is a REbuild. as stated before, REbuild will bypass the cache, so thats expected to fail.
