LINQKit LinqKit.Core 1.2.5 is not compatible with net8.0

Doesn't appear the latest version is supported yet, even though you have create LinqKit.Microsoft.EntityFrameworkCore for 8.1.5.

error NU1202: Package LinqKit.Core 1.2.5 is not compatible with net8.0 (.NETCoreApp,Version=v8.0). Package LinqKit.Core 1.2.5 does not support any target frameworks.

Any update on when this might be enabled?

It supports .NET Standard 2.1

So .NET should work ?

Dec 06 '23 09:12 StefH

All I know is that the compiler won't build in a net8.0 project.

@Fosol When creating a default .NET 8 console app:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="LinqKit.Core" Version="1.2.5" />
  </ItemGroup>

</Project>

With this code:

using LinqKit;

namespace ConsoleAppLinqCore
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var predicate = PredicateBuilder.New<Program>(true);
        }
    }
}

The application compiles fine:

And runs fine:

I tried LinqKit and LinqKit.Microsoft.EntityFrameworkCore, however both failed to compile.

I'll try LinqKit.Core and see if it works.

Dec 07 '23 16:12 Fosol

Both LinqKit and LinqKit.Microsoft.EntityFrameworkCore can be used in a .NET 8 console app (I did some tests), however the LinqKit NuGet is not what you would want to use, because for backwards compatibility reasons, this package has a dependency on the old EntityFramwork version 6.x

Dec 08 '23 08:12 StefH

I don't know how you're getting it to work. When I build it fails with any of the libraries.

With LinqKit.Core <PackageReference Include="LinqKit.Core" Version="1.2.5" /> Package LinqKit.Core 1.2.5 is not compatible with net8.0 (.NETCoreApp,Version=v8.0)

With LinqKit <PackageReference Include="LinqKit" Version="1.2.5" /> Package LinqKit 1.2.5 is not compatible with net8.0 (.NETCoreApp,Version=v8.0)

All are in projects with the following.

Are you using Visual Studio 2022 ?

Dec 12 '23 16:12 StefH

I'm using vscode.

dotnet --version = 8.0.100

Dec 12 '23 16:12 Fosol

PS C:\projects\ConsoleAppLinqCore> dotnet --version
8.0.100

VSCode:

Dec 13 '23 07:12 StefH

I have a new project

dotnet new console

Here is my test.csproj file.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>

    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="LinqKit" Version="1.2.5" />
  </ItemGroup>

</Project>

Here is the error on dotnet restore or dotnet build.

error NU1202: Package LinqKit 1.2.5 is not compatible with net8.0 (.NETCoreApp,Version=v8.0). Package LinqKit 1.2.5 does not support any target frameworks.
error NU1202: Package LinqKit.Core 1.2.5 is not compatible with net8.0 (.NETCoreApp,Version=v8.0). Package LinqKit.Core 1.2.5 does not support any target frameworks.

I don't know why this doesn't work. I don't know what's different with my computer.

But that error is coming from somewhere.

Dec 13 '23 13:12 Fosol

You are using Linux or Apple or Windows?

Dec 13 '23 14:12 StefH

Windows 11 Enterprise

Sorry, I cannot help you.

Adding a the package to an empty project gives this output for me:

Thanks for taking the time to look into it. I'll attempt it on another computer and see what happens. Perhaps I need to reinstall the SDK.

Dec 13 '23 16:12 Fosol

@StefH can we reopen this ticket?

The error disappears if I change to LinqKit 1.2.4, but I need to test the application to see if it works.

Jun 12 '24 20:06 Fosol

This error still exists even when using LinqKit:1.3.0

error NU1202: Package LinqKit.Core 1.2.5 is not compatible with net8.0 (.NETCoreApp,Version=v8.0). Package LinqKit.Core 1.2.5 does not support any target frameworks.

Essentially none of the versions of LinqKit work in with net8.0.

@Fosol Can you please provide an example project?

Sep 19 '24 06:09 StefH

Well the most amazing thing occurred today. After rebooting my system it worked... Here are the things I did over the last day that may have been related.

1st Possible Action

I was trying to resolve the above issues so I cleared nuget cache.

dotnet nuget locals all --clear

This didn't fix the issue. However, I didn't reboot after doing this.

2nd Possible Action

This is unlikely related, however it is something I was actively doing on my machine.

The Windows Security tools would not open. I looked around the internet how to fix it. I did everything that has been posted on the subject. Rebooted several times. Eventually I my Windows Security tools started working again.

And voila now today I am able to build with the latest version of LinqKit. After over a year of having this issue, it magically disappeared.
