+# 💻.NET Installation Scripts for Linux, macOS, and Windows
+
+Sempre gostei de automação seja usando [Chocolatey](https://chocolatey.org/), Python, Bash, Powersheel etc... tenho até um [dotfiles (GNU/Linux Ubuntu e Windows 10)](https://github.com/neiesc/dotfiles), depois que fiquei sabendo que o dotnet tem uma documentação sobre instalar dotnet com scripts resolvi compartilhar, pois, pode passar despercebido para muitos.

+
+O site [.NET Install scripts](
+https://dotnet.microsoft.com/download/dotnet/scripts) como no próprio site fala scripts para instalar .NET Core no Linux, macOS e Windows. Na [documentação](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script?WT.mc_id=dotnet-35129-website) tem o modo de uso sendo bem simples:

+
+Exemplos para instalar versão LTS:
+
+No Windows:
+```powershell
+&powershell -NoProfile -ExecutionPolicy unrestricted -Command "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; &([scriptblock]::Create((Invoke-WebRequest -UseBasicParsing 'https://dot.net/v1/dotnet-install.ps1'))) -Channel LTS"
+```
+
+Linux/macOS:
+```bash
+curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --channel LTS
+```
+
+PS1: Caso você tenha o dotnet já instalado é recomendado você remover todos e instalar em forma de script como esse post mostra.
