Resolution:
I have 2 projects in a solution, and I am not sure why I am running into this error, when i building 1st project getting above error.
adding the following two line to <PropertyGroup> error are resolved
<Project Sdk=”Microsoft.NET.Sdk.Web“>
<PropertyGroup>
<GenerateAssemblyInfo>false</GenerateAssemblyInfo>
<GenerateTargetFrameworkAttribute>false</GenerateTargetFrameworkAttribute>
</PropertyGroup>
</Project>
once you have build project error will be resolved.
