带有.net core 3.0的ICollectionView [英] ICollectionView with .net core 3.0

问题描述

我正在将项目从经典的.net迁移到.net core 3.0.我在ViewModel ICollectionView接口中使用它，但.net core 3.0框架无法识别它.

I'm migrating my project from classic .net to .net core 3.0. I use in my viewmodel ICollectionView interface and it is not recognized in .net core 3.0 framework.

我添加了几个nuget软件包以尝试使其正常运行，但是没有运气.

I added several nuget packages to attempt to make it work, but with no luck.

Microsoft声称System.ComponentModel定义了icollectionview(

Microsoft claims System.ComponentModel defines icollectionview (https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.icollectionview?view=netcore-3.0), but it is not found. I also tried to include windowsbase, but it's not found either.

我的环境有问题吗?我错过了什么吗?

Is my environment faulty ? Did I miss something ?

感谢您的帮助.

这是一个可在.netcore3项目下编译的小类:

Here is a small class to compile under a .netcore3 project:

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello World!");
        ICollectionView col =new CollectionViewSource().View;
        col.Filter = null;
        col.Refresh();
    }
}

感谢ALFA for Microsoft.Windows.SDK.Contracts在.net核心上提供ICollectionView接口，但不幸的是，它还不完整:未实现过滤器和刷新.

Thanks to ALFA for Microsoft.Windows.SDK.Contracts which offer an ICollectionView interface on .net core, but unfortunatly, it is not complete: Filter and refresh are not implemented.

推荐答案

您需要从以下位置编辑项目文件 YourProjectName.csproj :

You need to edit your project file YourProjectName.csproj from this:

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

<PropertyGroup>
   <TargetFramework>netcoreapp3.0</TargetFramework>
</PropertyGroup>

对此:

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

<PropertyGroup>
   <TargetFramework>netcoreapp3.0</TargetFramework>
   <UseWPF>true</UseWPF>
</PropertyGroup>

对我有帮助.
