Syntax: b[reak] [ClassName.Method | FileName:LineNo] | [module!ClassName.Method+IlOffset]
Examples:
[p#:0, t#:5] mdbg> b LowLevelDesign.Samples.MySqlWebEventProvider.CreateCommandText
Breakpoint #1 bound (LowLevelDesign.Samples.MySqlWebEventProvider::CreateCommandText(+0))
To delete a breakpoint: del[ete] [#num], eg.
[p#:0, t#:9] mdbg> b
Current breakpoints:
Breakpoint #1 bound (LowLevelDesign.Samples.MySqlWebEventProvider::CreateCommandText(+0))
[p#:0, t#:9] mdbg> del 1
Conditional breakpoints can be created using the when statement:
[p#:0, t#:0] mdbg> b TraceReader.cs:33
Breakpoint #1 bound (line 33 in TraceReader.cs)
[p#:0, t#:0] mdbg> when BreakpointHit 1 do "p line"
[p#:0, t#:0] mdbg> when
1. when BreakpointHit (Number=1) do: p line

To show sources at the current location use sh[ow] [lines], eg:
[p#:0, t#:6] mdbg> sh

77:* {
78 // choose the table to which we will write events
79 String eventsTable;
The source path can be set using pa[th] [pathName]:
[p#:1, t#:4] mdbg> pa
After the source path is set the debugger somehow is able to resolve source files relevant paths.
To print a variable value use: print [var] | [-d], eg.
[p#:0, t#:6] mdbg> p -d

- Getting source code from a source server from Mdbg http://blog.ranamauro.com/2010/02/getting-source-code-from-source-server.html
Usage: mdbg [program [ arguments... ] ]
mdbg !command1 [!command2 !command3 ... ]
When program name is entered on the command line, the debugger
