Add support for Visual Studio 2026 and .NET 10

[luronumen]

Actual Result

• The MudBlazor template is not listed in Visual Studio 2026
• dotnet new mudblazor command creates the project to net9

Expected Result

• The MudBlazor template should be listed in Visual Studio 2026
• dotnet new mudblazor command should create the project to net10

Steps to Reproduce the Issue

1. Install the Visual Studio 2026 available at: https://visualstudio.microsoft.com/
2. Run the following command to install the MudBlazor template: dotnet new install MudBlazor.Templates
3. Open the Visual Studio 2026: Verify that the MudBlazor template is not listed
4. Run the following command to create a MudBlazor Server application: dotnet new mudblazor --interactivity Server --name MyApplication --all-interactive: Verifiy that the application is created for net9 instead of net10

I have the MudBlazor template listed, even without reinstalling it.

Perhaps you didn’t select the option to migrate all settings from VS 2022.
I’d suggest doing something like this:

dotnet new --uninstall MudBlazor.Templates
dotnet new install MudBlazor.Templates

If it still doesn’t show up, I’d recommend using Send Feedback → Report a Problem in the IDE, as we’re not responsible for the template installation process. There are no special requirements from MSFT for VS 2026, so it should work out of the box.

As for the .NET 10 templates themselves, we probably won’t rush to update them until the next major version of MudBlazor is released. This way, we can avoid having to redo things back and forth, as our resources are limited.

Hi @ScarletKuro,

Thank you so much for your quick reply!

Exactly! Instead of updating Visual Studio from version 2022 to version 2026, I uninstalled version 2022 and then installed version 2026.

By updating this way, I simulated a clean installation of Visual Studio 2026, which showed that even after installing the template, it is not shown as an option for project creation, as you can see in the images below:

This problem is probably happening because when doing a clean installation of Visual Studio 2026, only .NET 10 is installed, and since the template is for .NET 9, it is not listed when creating a new project. Does what I said make sense?

Same problem here ...

The template seems to only have built-in support for net9.

Does what I said make sense?

If you have only .NET SDK 10 installed, it makes sense that you don't see it in the VS UI, as it only supports .NET 9.
You can install .NET 9, create project and then just manually upgrade it to .NET 10, it will work.

The template seems to only have built-in support for net9.

Yeah, you can create the .net 9 templates and upgrade it.

[edson-v-schmitt]

Yeah, you can create the .net 9 templates and upgrade it.

Not sure if this was an attempt at a cheeky joke ... but ... if I'm manually upgrading between .net versions then why am I using the template at all?

Anyways ... I'll have a look at the repo and see if I can suggest a PR to add the ability to generate templates in multiple different TFMs.

[w3ori]

There is no option for .NET 10 now.

This works for me: #507
