Resolve: unknown type: System.Diagnostics.DebuggerBrowsableState

NETMF & Gadgeteer
1

Hi all - I believe I’ve made some sort of common mistake, but I can’t for the life of me figure out what it is.

A program that I wrote and debugged yesterday is “suddenly” not working anymore (note the quotes, I MUST’ve done something, of course!)

The output from debug is the following:


Found debugger!

I am running the 4.3 Version of .Net Micro Framework, and the corresponding Libraries.
Could it be that I am simply missing some framework Library? According to the Object browser, the missing type “System.Diagnostics.DebuggerBrowsableState” can be navigated to, but exerience has taught me that namespaces are not necessarily tied to the dll. Any input largely appreciated!

@ andre.m - Thanks!

The trick was to add the namespace and enum manually. Wonder why it worked yesterday though

3

The same problem after updating to GHI Electronics NETMF SDK 2015 R1. Adding enum manually doesn’t work.

4

I’ve just gone through this exercise, and the usual hack did work for me. How did you add the enum? Is it in the right namespace? Can you post the code you are using?

5

Yes, I’m using exactly the same code and it doesn’t work for me.
Cerb40
.NET MF SDK 4.3.1.0
GHI SDK 4.3.7.10 (2015 R1)
VS2015

6

BTW, is it OK that I installed netmf-v4.3.2-SDK-QFE2-RTM but dlls version is 4.3.1.0?

7

And one more bug: I can’t use foreach loop for strings after that SDK update.

8

Yes, it has additional references. Working version of my project is here: imBMW/Sources/NET-MF at master · toxsedyshev/imBMW · GitHub
(Devices/V2)

9

I tried to add that enum to both main app and my dll (I don’t use any other dlls except NETMF and GHI) - the same problem.

Regarding string enumeration, I don’t care - changed foreach loop to for loop and improved performance this way :slight_smile: Now I want to fix the bug with enum that prevent my project to run.

10

Attached references of the solution. Tried to add enum to both projects.

11

BTW, I removed mscorlib from references and when I add it back to the projects - nothing is happened.

12

After several tries of removing/adding references and VS restarting, hack with adding enum started working!

But anyway, it should be fixed.

@ digitaldias - have you added an issue to bug tracker?

Any news here? I have the same problem.
