NLOG Error

[Anonymous]

I am getting the following NLOG Error when I do
FileTarget _target = new FileTarget();

Error: {“LayoutRenderer cannot be found: ‘longdate'”}

StackTrace:

Heya GregJ,

Got your comment ref the using statements. Completely agree that they should also be given in the article, I’m updating it now.

Regarding your exception can you please tell us what platform, i.e. .net2, .net3.5, ios, …?

Regards,
Marc

I am using .net4 on windows 7.

This is a really strange error, we’ve never had any issues with NLOG in windows. To help debug the problem could you possibly download the source zip bundle, if you have not already, and run the ExampleConsole project (enable logging when prompted) to see if your get the same exception?

It worked using the example project. The differences I see are that I am using
NetworkComms within a class in a library I wrote.

Then the main application is creating an instance of that class.

I also notice that the ExampleConsole refrences NLOG directly, which I am not able to do from my libarary because it errors out and says the methods are available both in NLOG and NetworkComms.

Some questions that should find a solution:

1. Are you enabling logging from within your object instance or the top level application?

2. Are you referencing the merged single DLL, i.e. Core/Complete, or the individual DLLs?

3. Can you elaborate what you mean by “I also notice that the ExampleConsole refrences NLOG directly, which I am not able to do from my libarary because it errors out and says the methods are available both in NLOG and NetworkComms.”
Once you reference the NetworkCommsDotNetCore.dll you should be able to add namespace references to NLOG without issues?

I fixed it. I was referencing complete. Changed to Core and then referenced NLOG. Issue resolved.

Brilliant. Many thanks for the update.

It’s worth noting that the complete DLL already contains NLOG so if you use the complete DLL you should not reference NLOG additionally.

Marc

After some further testing I discovered this error is caused by a version bug between .Net4 and .Net4.5 assemblies. The single DLLs were built on a windows 8 machine which turns out was secretly using .Net4.5 assemblies, which then breaks if run on a machine which only has .net4. A quick fix is to use either the .net3.5 or .net2.0 build or install .net4.5 but in the long run we will find a way of ensuring this workaround is not necessary.
