Here's how to install the new runtime in Visual Studio and Visual Studio for Mac. ## 1\. Install .NET Core 3 Azure Functions v3 runs on .NET Core 3\. To install .NET Core 3, visit [Download .NET Core](https://dotnet.microsoft.com/download/dotnet-core?WT.mc%5Fid=functionsv3-codetraveler-bramin&ref=codetraveler.io). I recommend selecting the latest `LTS` version. `LTS` stands for `Long Term Support`, meaning that Microsoft is committed to supporting this specific version of .NET Core with bug fixes for approximately 2-3 years. As of today, the current `LTS` version of .NET Core is [.NET Core 3.1](https://dotnet.microsoft.com/download/dotnet-core/3.1?WT.mc%5Fid=functionsv3-codetraveler-bramin&ref=codetraveler.io). ## 2\. Update the CSPROJ Let's ensure our `csproj` file has been updated for Azure Functions v3\. We'll need to set the following three things: - [**Target Framework**](https://docs.microsoft.com/dotnet/standard/frameworks?WT.mc%5Fid=functionsv3-codetraveler-bramin&ref=codetraveler.io) is `netcoreapp3.1` (or higher) - [**Microsoft.NET.Sdk.Functions** NuGet Package](https://www.nuget.org/packages/Microsoft.NET.Sdk.Functions?ref=codetraveler.io) is v3.0.1 (or higher) - **AzureFunctionsVersion** is `v3` Here is an example from my GitTrends app: [https://github.com/brminnick/GitTrends/blob/master/GitTrends.Functions/GitTrends.Functions.csproj](https://github.com/brminnick/GitTrends/blob/master/GitTrends.Functions/GitTrends.Functions.csproj?ref=codetraveler.io) ```xml netcoreapp3.1 v3 PreserveNewest PreserveNewest Never ``` ## 3a. (Visual Studio) Update Azure Functions Runtime **Note:** If you're using Visual Studio for Mac, skip to the next section Let's now install the Azure Functions Runtime for [Visual Studio 2019](https://visualstudio.microsoft.com/vs?WT.mc%5Fid=functionsv3-codetraveler-bramin&ref=codetraveler.io) 1. In [**Visual Studio**](https://visualstudio.microsoft.com/vs?WT.mc%5Fid=functionsv3-codetraveler-bramin&ref=codetraveler.io), select **Create a new project** ![](https://storage.ghost.io/c/dc/c2/dcc2e43e-24f8-46bb-a899-9c446f3ef794/content/images/2020/02/Screen-Shot-2020-02-12-at-3.31.20-PM.png) Visual Studio, Create New Project 2\.

Conclusion Updating to Azure Functions v3 requires a couple steps: - Installing .NET Core 3 - Updating our `csproj` - Updating Visual Studio's Azure Functions Runtime If you'd like to see an existing Azure Functions project using v3, feel free to check the Azure Functions Backend in my GitTrends app: [https://github.com/brminnick/GitTrends/tree/master/GitTrends.Functions](https://github.com/brminnick/GitTrends/tree/master/GitTrends.Functions?ref=codetraveler.io) ![](https://storage.ghost.io/c/dc/c2/dcc2e43e-24f8-46bb-a899-9c446f3ef794/content/images/2020/02/EQm9wkaUYAADq2V-1.jpeg)
