Migrate to SLNX

[askpt]

Requirements

Description:

We must migrate our solution files from the traditional .sln format to the new .slnx format. This change is necessary to take advantage of the enhanced features and performance improvements offered by the .slnx format.

Tasks:

• Identify all existing .sln files in the repository.
• Convert each .sln file to the .slnx format using the .NET CLI.
• Update any build scripts or tools referencing .sln files to use the new .slnx files.
• Test the new .slnx files to ensure they work correctly with our existing development and CI/CD workflows.

Notes

For more information on the .slnx format and how to migrate, please refer to the official documentation: https://devblogs.microsoft.com/dotnet/introducing-slnx-support-dotnet-cli/

seeing that we're using dotnet-format x.sln in pr validation request, may need to wait for the dotnet-format slnx support in SDK, which may support in 9.0.300 in April servicing release

Thanks for reporting this. We could do dotnet-format --verify instead, but since this is nice to have only, we can wait until the next servicing release.
