Converts between Windows PDB and Portable PDB formats.
Pre-release builds are available from Azure DevOps public feed: https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-tools/nuget/v3/index.json (browse).
The converter is available as a command line tool as well as a library. Both are distributed as NuGet packages.
Pdb2Pdb.exe <dll/exe path> [/pdb <path>] [/out <path>] [/extract]
| Switch | Description | 
|---|---|
/pdb <path> | 
Path to the PDB to convert. If not specified explicitly, the PDB referenced by or embedded in the DLL/EXE is used. | 
/out <path> | 
Output PDB path. | 
/extract | 
Extract PDB embedded in the DLL/EXE. | 
/sourcelink | 
When converting to Windows PDB do not convert SourceLink to srcsrv format. By default both SourceLink and srcsrv are included in the converted PDB. | 
/nowarn * | 
Suppress all warnings. All warnings are reported by default. | 
/nowarn <n1,n2,...> | 
Suppress specified warning. | 
/srcsvrvar <name>=<value> | 
Add specified variable to srcsvr stream. Only applicable when converting to Windows PDB and /sourcelink is not specified. | 
/extract and /pdb are mutually exclusive.
Example: Create and build .NET Core Standard library and convert its Portable PDB to Windows PDB to be published to Symbol Store.
> dotnet new classlib
> dotnet build
> cd bin\Debug\netstandard2.0
> mkdir SymStore
> Pdb2Pdb MyProject.dll /out SymStore\MyProject.pdb
The package provides the following public APIs:
