[Bug] `System.InvalidOperationException: There is an error in XML document (0, 0).`

[WhiteBlackGoose]

I cannot reproduce it properly, it may or may not occur. Here's the stacktrace:

Unhandled exception. System.InvalidOperationException: There is an error in XML document (0, 0).

I just added additional diagnostics for this case (130f0fb)

[WhiteBlackGoose]

Hmmm, why can it be happening though?

Also mb constrain the exception to InvalidOperation one? 😅

To find out you need to debug the disassembler, here is how you can do it: https://benchmarkdotnet.org/articles/contributing/disassembler.html#how-to-debug-the-disassembler

With all the improvements we did for diassembler in 0.13.2 this issue should be gone now
