var sampleMethodInvocation = syntaxRoot
.DescendantNodes()
.OfType<InvocationExpressionSyntax>()

var sampleMethodSymbol = semanticModel.GetSymbolInfo(sampleMethodInvocation).Symbol;
var referencesToSampleMethod = await SymbolFinder.FindReferencesAsync(sampleMethodSymbol, document.Project.Solution);
