How to Install .NET SDKs

⚡ Quick Answer

To install .NET SDKs for LazyMagic: Check existing installations with dotnet --list-sdks, then download and install .NET 8 and .NET 9 SDK from Microsoft's download page if needed. If you have Visual Studio IDE installed, use the Visual Studio Installer to install any required SDKs.

What is the .NET SDK?

.NET SDK is Microsoft's latest software development kit for building .NET applications. New versions of .NET are released each year. At the time of writing we are on .NET 9.

Short Term Support (STS) and Long Term Support (LTS)

Microsoft releases alternates each year between a STS and LTS release. Even numbered releases are LTS and odd numbered releases are STS.

There is no stability difference among STS and LTS releases. Older releases are highly compatible with newer releases.

The LazyMagic Client libraries track the latest release available. This allows client applications, like MAUI apps and Blazor Webassembly apps to leverage the latest fast moving developments in client frameworks.

The LazyMagic Service libraries track the latest release supported by AWS. At the time of writing, this is .NET 8. AWS has a policy to only support LTS software. In our opinion, this makes little sense in the case of Microsoft's .NET platform, but there it is. Generally, the LTS versions of .NET, even if they lag a bit in features from the latest STS version, are more than sufficient for the development of service side software.

Because of the AWS limitation, we may require multiple versions of the SDK be installed.

As of Sept. 2025 you will need .NET 9 and .NET 8 SDKs.

Note that it is possible to use later versions of the .NET SDK on the service side. It does require a little extra work to build the containers (like Lambdas or ECS containers).

Step-by-Step Installation Guide

Step 1: Check Existing .NET Installations

First, check which .NET versions are already installed on your system:

dotnet --list-sdks

If you see the required versions of .NET listed, you can skip this installation.

Step 2: Download required .NET SDK (if needed)

📖 Official .NET Download Page
Select the required .NET SDK for your operating system

Step 3: Install .NET SDK(s)

Run the downloaded installer
Follow the installation wizard
Accept the license terms
Complete the installation

Step 4: Install MAUI Workloads

Run: dotnet workload install maui

Verification

To verify .NET SDK is properly installed:

Open a new command window or PowerShell
Run: dotnet --version
Confirm the version
Run: dotnet --list-sdks
Verify the required .NET SDK versions are listed
Run: dotnet workload list

Important Notes

Visual Studio Users: If you installed Visual Studio IDE, .NET 9 SDK is already included

Troubleshooting

Common Issues

Path not found: Restart your terminal after installation to refresh environment variables
Version conflicts: Multiple .NET versions are normal and won't conflict
Installation failed: Ensure you have sufficient disk space and administrator privileges

Next Steps

After successfully installing .NET 9 SDK, proceed to install the LazyMagic CLI Tool in the next step of the LazyMagic setup process.
