TL;DR Since the original download is no more, here's what I found on the dell forums:
Standalone package: Microsoft Update Catalog - KB4457144
I had the exact same error message (apart from the directories) on Win7 with a newer VC++ redist already present.
The package contains the KB2533623 that we want. Details of KB4457144: September 11, 2018—KB4457144 (Monthly Rollup)
After installation and a reboot, dotnet new console
goes through without an error.
Dell forum source: Microsoft Windows 7 Update KB2533623 needed to install Dell Update Package (DUP)
I faced the same error and I checked my Web API Program.cs
class and found that: .UseIISIntegration()
is missing. I added it and the problem solved.
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args).UseStartup<Startup>().UseIISIntegration();
}
Though it is very late but I am trying to list steps to solve this issue hope, this helps! I followed the solutions provided on this link but in my case the deployment environment was the issue. listing down the steps I followed to fix this.
In my case there was windows7 x64 and according to this instruction: https://docs.microsoft.com/en-us/dotnet/core/install/windows?tabs=net50
Windows 7 SP1 ESU - Microsoft Visual C++ 2015-2019 Redistributable 64-bit / 32-bit
There was no KB3063858 on my machine. After installation my application has started.
(I uset asp net 5)
