ASP.NET Core — Switch .NET Core SDK Version

2 min readJul 31, 2019

In .NET Core, sometimes, we need to install different .NET Core versions for different applications, then the problem is how we switch .NET Core version for different applications.

Prior to talking about the solution, there are some commands which are really useful to know what versions you have installed on your server

List all .NET Core SDKs

dotnet --list-sdks

List all .NET Core Runtimes

dotnet --list-runtimes

List all .Net Core info

dotnet --info

Two solutions how to switch .NET Core SDK version

Create a global.json file, then put it under the folder which you want to switch .NET Core SDK

{
    "sdk": {
      "version": "2.2.300"
    }
}

If you have a .csproj file, you can change the TargetFramework element

<PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
    ....
  </PropertyGroup>
