How could I compile the code has interceptor with roslyn code analysis package

[WeihanLi]

Hi there, I'm trying to compile C# code contains an interceptor, if I compile the code directly, would get an error likes below

error CS9137: The 'interceptors' experimental feature is not enabled in this namespace. Add '<InterceptorsPreviewNamespaces>$(InterceptorsPreviewNamespaces);CSharp12Sample.Generated</InterceptorsPreviewNamespaces>' to your project.

we could define the InterceptorsPreviewNamespaces property in a project file, then how could I specify the InterceptorsPreviewNamespaces for the Roslyn runtime compile process?

Thanks very much

Find it, we could update the Features, for example:

var parseOptions = new CSharpParseOptions()
    .WithFeatures(new KeyValuePair<string, string>[]
    {
        new("InterceptorsPreviewNamespaces", "CSharp12Sample.Generated")
    });
