You have to update .csproj file to support C# 8.0 version and enable nullable option,

  <PropertyGroup>
    <LangVersion>8.0</LangVersion>
    <Nullable>enable</Nullable>
  </PropertyGroup>

How to edit .csproj file?

  • Right click on GUI Version 1 project -> Click on Edit Project file -> Update file with above two tags -> Reload project.

Alternate way:

  • Right click on GUI Version 1 project -> unload project -> Edit project File -> Update file -> Reload project.
