I have a AzureFunctions project that I needed to upgrade to .NET standard 2.1 (from 2.0) All of my other projects in the solution load and compile correctly but this AzureFunctions project is throwing this error:
Error System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified. File name: 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'
I've verified all the nuget packages are updated, what else could it be?
Thanks!
Some times you receive this error because you have referenced a library/nuget package that target the incompatible .Net standard. example: If you create project that target to .Net Core 2.2 and you try to add the library which target .net standard 2.1 then you will get the same error because .Net Core 2.2 is compatible with .net standard 2.0 or lower so you can add package/library that target to .Net Standard 2.0 or lower version.
