Compatability with .slnx format

[MPapst]

Description

Parse and map the newly supported slnx file format for solution files.

Previously mentioned in #1375, but with .NET SDK 9.0.2x now officially supported.

Usage Example

• Should work in the same way as the current solution file parsing.
• Should be completely transparent for the developer

Alternative

Use

[Parameter] readonly string Solution;

instead of a parsed solution-object.

Could you help with a pull-request?

Yes

This library provided by Microsoft could be used for that:

I would like to add an parser.

Would you prefer manual parsing or adding the MS parser?
An additional package (if that is even possible, haven't looked up the architecture) or inline?

Do we have any updates on this? It looks like with .NET 10 Microsoft is moving toward making the slnx format the default.

To be honest - I haven't started and do not plan to start without an answer with a preference from @matkoch .

FYI, if you don't rely on the parsing, you can simply switch from this:

[Solution] readonly Solution Solution;

to this:

[Parameter] readonly string Solution;

@MPapst maybe you could add this as an Alternative to your issue description.
