added support for csproj parsing

[macnev2013]

Description

This PR adds support for parsing csproject file in the dotnet project.

Potential Issue

• This parser may not return the exact version of the dependancy since the parser is based of csproj file.
• Solution: To avoid such issue we can use the lock files as described below.

Projects with Lock files

Lock file provides constant versioning for the dependancies present. To generate a lock file,

• Add the following options to your csproj file.

  <PropertyGroup>
    <RestorePackagesWithLockFile>true</RestorePackagesWithLockFile>
  </PropertyGroup>

• Once this configuration is added, run dotnet restore - this will generate a package.lock.json file in your repo.
