Pull request overview
This PR updates the SDK's target framework from net10.0 to net11.0 throughout the repository. Despite the PR title saying "Update the sdk target to net10.0", the changes actually update FROM net10.0 TO net11.0, aligning with the next .NET version. The PR includes updates to build infrastructure, test projects, MSBuild targets, and supporting code changes to leverage net11.0 features.
Key changes include:
- Updating the SDK version in global.json to 11.0.100-alpha.1.25614.102
- Updating SdkTargetFramework and NetCurrent properties to net11.0 in Directory.Build.props
- Adding net11.0 to supported target frameworks and updating test data structures
- Code improvements leveraging newer .NET APIs (StringBuilder.Append with repeat count, partial class for EventSource)

Shouldn't this be just 10.0.0?

It's also failing the test step I think as it appears to be failing in InstallDotNetSharedFramework because 10.0.0 is already installed (and lastexitcode doesn't get set). Seems like it doesn't actually set the last exit code if it skips the install and that breaks the script
The install-scripts won't always set last exit code like if the runtime is already installed so pre-set it.
…on't have an 11 runtime yet. There's not a good central place to set this as different tests use different DBPs so try setting this in the run tests script

@marcpopMSFT this is a shipping file in the SDK and can't use this repo's infrastructure:
C:\Program Files\dotnet\sdk\10.0.100\Sdks\Microsoft.NET.Sdk.BlazorWebAssembly\targets\Microsoft.NET.Sdk.BlazorWebAssembly.5_0.targets

We could avoid these hardcodes in the future if SDK would expose a latest TargetFramework property. I think there's a tracking issue for that somewhere here in this repo, cc @baronfel
