VSCode: Project is created without sln but expects one

[jojorne]

Describe the bug

If you do a dotnet new avalonia.mvvm, a new project will be created.
If you try to edit any axaml file, you'll get a must build first warming.
This warning never goes away! Upon a closer inspection, I noticed this:

[info] parser process args: C:\WINDOWS\system32\cmd.exe,/d,/s,/c,"dotnet "~\.vscode\extensions\avaloniateam.vscode-avalonia-0.0.29\solutionParserTool\SolutionParser.dll" "~\GetStartedApp\GetStartedApp.sln""

It calls for a SolutionParser which there is no sln file to parse.

By doing a dotnet new sln followed by dotnet sln add fixed the issue.
