Once you've successfully decompiled an assembly, it's possible to save it as a Visual Studio project file (.csproj), which can significantly expedite the process of recovering lost source code from older assemblies. dotPeek offers the capability to locate local source files using PDB files, or alternatively, to retrieve source code from various source servers like Microsoft Reference Source Center or SymbolSource. Additionally, dotPeek functions as a symbol server, providing the necessary information to the Visual Studio debugger for effective assembly code troubleshooting. Many features of dotPeek are derived from ReSharper, including both contextual and non-contextual navigation options, usage searches, and various views for code structure and hierarchy. You can utilize the Find Usages feature to track down every instance of a symbol, whether it be a method, property, local variable, or another type of entity. The Find Results tool window is particularly useful, as it allows you to organize usages, easily navigate among them, and access them directly in the code view area. Overall, dotPeek proves to be an invaluable tool for developers dealing with legacy code and assembly management.
