Get started

To get started with ASP.NET Core in .NET 6 Preview 5, install the .NET 6 SDK.

If you’re on Windows using Visual Studio, we recommend installing the latest preview of Visual Studio 2019 16.11. Visual Studio 2022 Preview 1 is also releasing today and .NET 6 Preview 5 is included in that release. If you’re on macOS, we recommend installing the latest preview of Visual Studio 2019 for Mac 8.10.

To get setup with .NET MAUI & Blazor for cross-platform native apps, see the latest instructions in the .NET MAUI getting started guide. Be sure to also check out the Announcing .NET MAUI Preview 5 blog post for all the details on what’s new in .NET MAUI in this release.

Note: .NET MAUI is not yet supported in Visual Studio 2022 Preview 1. For .NET MAUI development, please use the latest preview of Visual Studio 2019 16.11 instead.

To install the latest .NET WebAssembly tools for ahead-of-time (AOT) compilation and runtime relinking, run the following command from an elevated command prompt:

dotnet workload install microsoft-net-sdk-blazorwebassembly-aot

If you’ve installed the .NET WebAssembly workload previously, you can update it to .NET 6 Preview 5 by running the following command from an elevated command prompt:

dotnet workload update

Note: There is a known issue with installing optional SDK workloads using the .NET 6 Preview 5 SDK included with Visual Studio 2022 Preview 1. To workaround this issue, install the .NET 6 Preview 5 SDK from https://dot.net/get-dotnet6 after installing Visual Studio 2022 Preview 1.
