What are you seeing?

slnx is an XML SLN format.
.net9 added slnx support dotnet new sln -f slnx and latest VS opens and builds such solution.

src/Cake.Common/Tools/DotNet/Sln is missing slnx.

What is expected?

slnx parsing and serialization using the same library dotnet-sdk is using https://github.com/microsoft/vs-solutionpersistence.

Hi!
I'd love to work on this issue as my first contribution to Cake (and to open source in general)

From what I understand, the goal here is to implement parsing and serializing support for .slnx files using https://github.com/microsoft/vs-solutionpersistence. Before I get started, could you clarify where this functionality would be used within Cake ?

Currently, dotnet sln add/list/remove commands are invoked directly via the CLI, so i'm not sure where parsing and serialization would come into play. Is this intended for a future feature, or is there an existing use case I might be missing ?

Thanks in advance

Is this issue resolved? Correct me if I am wrong but I do not see any issues using .slnx.
