[FileNotFoundException: Could not load file or assembly ‘JetBrains.Annotations, Version=18.104.22.168, Culture=neutral, PublicKeyToken=1010a0d8d6380325’ or one of its dependencies.

The workaround is to include the JetBrains.Annotations.dll in the bin folder of the application.
Use Nuget package manager console to install the exact version missing. Select the Web project as the default project (to install into that project) in Package Manager Console and enter this command:
install-package JetBrains.Annotations -version 22.214.171.124
The above is for version 126.96.36.199, for more info regarding downloading old versions of nuget packages, see this link:
