我根据 vs 2019 上的此链接安装了 Microsoft Reporting Services Projects VS2019 扩展和 ssdt ：https://learn.microsoft.com/en-us/sql/ssdt/download-sql-server-data-tools-ssdt ?view= sql-server-ver15

我在 vs 2019 中有 wpf 核心项目，但是当我右键单击并选择添加新项目时，没有可供选择的报表项目。我们如何将 .rdlc 文件添加到 wpf 核心项目？

I have this method:

public async Task<int> RemoveClassify(RemoveClassifyVm vm)
{
    return await _db.UserAccesses
        .Where(UserAccess => vm.userAccessIds.Any(userAccessId => userAccessId == UserAccess.Id))
        .ExecuteUpdateAsync(UserAccess => UserAccess
         .SetProperty(UserAccess => UserAccess.ClassId, null)
        );
}

but get error : Error CS0121 The call is ambiguous between the following methods or properties: 'SetPropertyCalls.SetProperty(Func<TSource, TProperty>, Func<TSource, TProperty>)' and 'SetPropertyCalls.SetProperty(Func<TSource, TProperty>, TProperty)'
