Rider

• Trusted projects
  • Introduced the concept of trusted projects to mitigate the risks associated with opening projects from unknown and untrusted sources.
  • When you open a project, Rider doesn’t execute any code from it and checks whether it is trusted or from a trusted location.
  • If the project currently is not trusted, the IDE will ask you to choose whether to open it in safe mode or full-trust mode. If the project currently is not trusted, the IDE will ask you to choose whether to open it in safe mode or full-trust mode.
  • If you open a project in safe mode, the IDE will disable all potential code execution upon opening. Since this makes it impossible to build an accurate project model, many IDE features, such as error highlighting, will be disabled. However, you can still browse the project’s contents and open its source files in the editor.
  • To avoid showing warnings for every project, the IDE allows you to define trusted locations. Projects in directories specified as “Trusted Locations” are always considered trusted.
  • To ensure that you get the untrusted project warnings only when something out of the ordinary is happening, It is recommended to add the directory where you usually create projects to your trusted locations.
