Assembly Explorer allows opening multiple assemblies and keeping a list of open assemblies and folders. You can traverse and explore all open assemblies. Expanding an assembly node lists namespaces within the assembly, which can be further expanded to types and type members, as well as assembly references, resources, and metadata. You can double-click any type to decompile it or fetch source from a symbol server (depending on your settings).
tip
To learn assembly properties (for example version, company, copyright), double-click the assembly in the Assembly Explorer and study the [AssemblyName].cs file that opens.
You can easily search symbols in all assemblies loaded in the Assembly Explorer — just use Search Everywhere (Ctrl0T or Shift twice) or Go to SymbolCtrlAltShift0T commands.
To switch the Assembly Explorer view, choose Assemblies on the title selector of the Explorer window:
