Microsoft.Cci.Pdb.PdbDebugException: Unknown custom metadata item kind: 6 - Raspbian #13

Hi, I'm trying to debug one of my projects on Raspberry PI (Raspbian). When I start debugging, I'm getting this:

Fatal error: Microsoft.Cci.Pdb.PdbDebugException: Unknown custom metadata item kind: 6 at Microsoft.Cci.Pdb.PdbFunction.ReadCustomMetadata (Microsoft.Cci.Pdb.BitAccess bits) [0x00000] in :0 at Microsoft.Cci.Pdb.PdbFunction..ctor (System.String module, ManProcSym proc, Microsoft.Cci.Pdb.BitAccess bits) [0x00000] in :0 at Microsoft.Cci.Pdb.PdbFunction.LoadManagedFunctions (System.String module, Microsoft.Cci.Pdb.BitAccess bits, UInt32 limit, Boolean readStrings) [0x00000] in :0 at Microsoft.Cci.Pdb.PdbFile.LoadFuncsFromDbiModule (Microsoft.Cci.Pdb.BitAccess bits, Microsoft.Cci.Pdb.DbiModuleInfo info, Microsoft.Cci.Pdb.IntHashTable names, System.Collections.ArrayList funcList, Boolean readStrings, Microsoft.Cci.Pdb.MsfDirectory dir, System.Collections.Generic.Dictionary`2 nameIndex, Microsoft.Cci.Pdb.PdbReader reader) [0x00000] in :0 at Microsoft.Cci.Pdb.PdbFile.LoadFunctions (System.IO.Stream read, Microsoft.Cci.Pdb.BitAccess bits, Boolean readAllStrings) [0x00000] in :0 at Microsoft.Cci.Pdb.PdbFile.LoadFunctions (System.IO.Stream read, Boolean readAllStrings) [0x00000] in :0 at Pdb2Mdb.Driver.Convert (Mono.Cecil.AssemblyDefinition assembly, System.IO.Stream pdb, Mono.CompilerServices.SymbolWriter.MonoSymbolWriter mdb) [0x00000] in :0

Then the application runs, but without Visual Studio catching exceptions or breakpoints. I was able to debug almost almost empty console app with just Console.ReadLine(); in it.

Same issue for me, except that the application won't even run.

I think there may be some conflict with other visual studio extensions. Could you check it?

gerardwknight commented 8 years ago

I get the same error Visual Studio 2015 Community Edition connecting to the remote debug server running on a Beagle Bone Black C with Debian. How do I check for a conflict with other extensions?

gerardwknight commented 8 years ago

The pdb error is resolved by using an updated version of pdb2mdb, see http://stackoverflow.com/questions/36900315/how-can-i-remotely-debug-a-c-sharp-net-4-5-winforms-application-on-a-raspberry

but then breakpoints don't work at all, with anything more complicated than a hello world app with a console.WriteLine breakpoint.

Did you use the latest version, v1.0.7?

gerardwknight commented 8 years ago

Yes I used v1.0.7, I'm going to try and use MonoDevelop softdebugging on the same system, and see if that works. I will let you know how it goes. Is there anything else I can do to help diagnose the problem?

techcap commented 8 years ago

@mikolus @etlam5123 Could you check the mono version? When I used mono v3.x, I get same errors. After updating to v4.2.3.4, the problem was solved.

techcap commented 8 years ago

@gerardwknight Could you explain more detail about "with anything more complicated than a hello world app"? Now it doesn't support the breakpoint on user threads.
