System.Web.pdb does not contain source-stepping information (.NET 472, .NET 4.8) #138

Open daiplusplus opened 4 years ago

daiplusplus commented 4 years ago

The source-code for Systdm.Web.dll is available, as is a System.Web.pdb file, however VS states that the PDB file doesn’t contain the extra source-stepping debug information.

This happens with the System.Web.pdb versions for .NET 4.7.2 and 4.8.

The same is true for System.Web.Extensions (4.0)

As a work-around, I used ILSpy to generate a PDB - but it had errors generating it so it’s a bit flakey.

for me as a workaround jetbrains dotPeek worked fine (without any errors) just remember to use generated (decompiled) C# files along with PDBs
