Hi SaiPrasadReddyY,

I checked your project and Ideed I found some differences in these dependencies:

CookieManager 2.0.0
Microsoft.AspNetCore.Http.Features 2.0.0
Microsoft.Extensions.Primitives 2.0.0

I can confirm that for all of these in my project (that builds without problems) the version included is 2.0.0 and the target platform is netstandard2.0.

Please could you check the import for these dlls (I am aware that at the moment this way of resolving dependencies is quite tricky)?

Regards,
Giuseppe
