.NET Core Web API Newtonsoft.Json Nuget Dependency Warning

Question

I have the following Web API solution structure with three projects in a .NET 5 Web Api

.  
+-- Api.csproj  
|   +-- Dependencies
|   |   +-- Projects
|   |   |   +-- Infrastructure.csproj
|   |   |   |   +-- Dependencies
|   |   |   |   |   +-- Projects
|   |   |   |   |   |   +-- Core.csproj
|   |   |   |   |   +-- Packages
|   |   |   |   |   |   +-- Serilog.Sinks.Telegram (2.0.1)
|   |   |   |   |   |   |   +-- Newtonsoft.Json (11.0.2)

When I build Infrastructure.csproj, it succeeds, but 2 strange issues

• Build warning Infrastructure.csproj : warning NU1603: Serilog.Sinks.TelegramClient 2.0.1 depends on Newtonsoft.Json (>= 10.0.0) but Newtonsoft.Json 10.0.0 was not found. An approximate best match of Newtonsoft.Json 10.0.1 was resolved.
• Looking in the \debug folder, I don't see any dlls for Serilog or Newtonsoft.

When I build Api.csproj, it succeeds, but again strange issues

• Build warning Infrastructure.csproj : warning NU1603: Serilog.Sinks.TelegramClient 2.0.1 depends on Newtonsoft.Json (>= 10.0.0) but Newtonsoft.Json 10.0.0 was not found. An approximate best match of Newtonsoft.Json 10.0.1 was resolved.
• Build warning Api.csproj : warning NU1603: Serilog.Sinks.TelegramClient 2.0.1 depends on Newtonsoft.Json (>= 10.0.0) but Newtonsoft.Json 10.0.0 was not found. An approximate best match of Newtonsoft.Json 10.0.1 was resolved.
• Looking in the \debug folder of the Api.csproj, I do see Serilog and Newtonsoft dlls.
• The Newtonsoft dll in debug has a version of 12.0.3.*

My Questions:

1. Is it right that there are no Serilog or Newtonsoft dlls in Infrastructure.csproj output folder?
2. Why am I getting a warning about Newtonsoft for the Api.csproj build when the dll is correctly put into output folder and the version is greater than the warning?
