[jira] [Commented] (THRIFT-5143) Can not use .NET std Thrift.dll in
.NET Framework due to missing dependency
[ https://issues.apache.org/jira/browse/THRIFT-5143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17077421#comment-17077421 ]
Mario Emmenlauer commented on THRIFT-5143:
------------------------------------------
I'm under the impression that in effect, the current .Net Standard bindings just work only in .Net Core 3.0 or later. I could not get them to work in .Net Framework and also not in .Net Standard (which is slightly crazy, but that's just it).

> Project: Thrift
> Issue Type: Improvement
> Components: netstd - Library
> Affects Versions: 0.13.0
> Reporter: Mario Emmenlauer
> Priority: Minor

> I could build Thrift .NET Std quite easily with dotnet on MSVC and Linux. However when trying to use it in a .NET Framework project, I can not get past the following error:
> {{src\gen-netstd\MyThriftAPI.cs(54,23): error CS0012: The type 'ValueTask<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. [C:\data\Debug\WPFGui\WPFGui_w0ude4yv_wpftmp.csproj]}}
> I've spent by now almost a full day to try different variations of workarounds. What I could find on the web was:
> * Switch to a newer .NET Framework. But 4.7.2 did not help.
> * Remove the reference to "System.Threading.Tasks.Extensions" from Thrift. This causes an alternative transitive reference to "System.Threading.Tasks.Extensions, Version=4.2.0.0" (last digit zero instead of one) instead, but does not help
> * Build Thrift with netstandard2.1 instead of netstandard2.0. This causes further undefined references of netstandard2.0.
> * Install "System.Threading.Tasks.Extensions" 4.5.3 from NuGet. This did not make any difference
> I'm at the end of my wit here. Did other people experience this problem, and/or who can use Thrift for .NET Std in a WPF application? Any tips or tricks? Help would be greatly appreciated!
