Problem with deploying pulse counter

I am trying to make a pulse counter with this example: [url][/url]

When starting the project in debug mode i get the following error:
Invalid native checksum: GHIElectronics.NETMF.System 0x74F83809!=0xC032A004
Link failure: some assembly references cannot be resolved!!
Assembly: FEZ Domino Puls Counter test ( needs assembly ‘Microsoft.SPOT.Native’ (4.1.2821.0)
Assembly: FEZ Domino Puls Counter test ( needs assembly ‘GHIElectronics.NETMF.Hardware’ (
Assembly: Microsoft.SPOT.Hardware (4.1.2821.0) needs assembly ‘Microsoft.SPOT.Native’ (4.1.2821.0)
Error: a3000000

All these assemblys are added as references and i get no compile errors. The only info i have found on this issue so far is that it could be a wrong version in either the FEZ SDK, .NET MF or the FEZ Domino firmware. I have downloaded and installed all this from the GHI site, and as far as i can tell all my versionas are correct.

[b]My FEZ Domino has:
ClrInfo.clrVersion: 4.1.2821.0
ClrInfo.targetFrameworkVersion: 4.1.2821.0

The NETMF SDK for NETMF v4.1 is SDK Version 1.0.15 (June 30, 2011)

MFDeploy and all the dll’s in \v4.1\Assemblies\le is v4.1.2821.0[/b]

Do any of you have an idea of what i am doing wrong and how to fix it?

Welcome to the forum!

Remove the references from project and then re-add them.

Thaks! Removing and re adding solved my problem.
After spending one full evening doing everything else the solution was oh so simple :-[

Thakyou for the quick response!


I’m having the same problem. Can’t wait to get home tonight to see if this fixes it :slight_smile:
