SonarCube not able to scan C# Code via AzureDevOps

I have Prepared a Azure Devops pipeline where i tasks are as follows

  1. UseNuget
    2 Nuget Restore
    3 Prepare analysis on SonarQube
    4 Build Solution
    5 Test Assemblies
    6 Publish Test Results
    7 Run Code Analysis
    8 Publish Quality Gate Results

I found that in logs although files with.cs extensions are scanned but in dashboard of SonarQube only Xml & Jscript are shown. Tried on SonarQube version 6.5 and 7.0 ( same results)
