Hey folks,
I'm facing a new problem. I have a library, created for "normal" .Net.
Now I want to use this library in an .NETMF project and I get the warning message "The project 'NeonMika.Config' cannot be referenced. The referenced project is targeted to a different framework family (.NETFramework)"
I expected that and thougt i just could change the framework in the properties page, but this is not working (just can choose from different .Net versions, not .NETMF)
In one sentence: Is there an easy way to use an .Net libaray?
Greets, Markus
Edit: I guess I should ask, do you have sources for this library? If not, ignore everything below :-)
I don't currently have access to a CF project file, but I don't think that there is an automatic way to do this so you might need to manually change the project file to include the appropriate targets, versions, etc. Once you have that building, you will most likely have a bunch of build errors as a result of using methods/classes that may only exist in big .NET which you can fix as you find them. I would use '#if CF' for the fixes so that the project is preserved for big .NET too and makes maintenance easier. I believe you can also conditionally include references/files in the project file (e.g., <Include condition=" '$(someCFIndicator)' = 'true'>MyCFFile.cs</Include>). If I get time tonight I will play around with this and see if I can help some more.

Yes, i have the source code, and it's not very big, but i'm just interested
I know that i just could create a netduino project, copy the cs files into this directory, add this files to the project and compile it. But from this moment on, i would have to maintaince 2 projects (.net and netmf) doing exactly the same...
It would be great if you can give me more information about "manually changing the project file"... Or about this topic in general. I hope you find somd time tonight
But already thanks for your help

We have a lot of libraries (10,000's or 100,000's of lines code) which we build for .NET MF, .NET CF, and .NET.
The .NET CF and .NET assemblies are often one-and-the same, but I find that we end up P/Invoking quite a bit and build "helper" libraries to fill in missing features in .NET CF...so we tend to build multiple projects for simplicity sake.
In theory, you should be able to build one project and switch between configurations to build it for .NET MF vs. .NET. Assuming that Visual Studio understands how to target different frameworks for different project configurations. Very interesting indeed.

You could create different configurations and condition on that configuration.
<Import condition=" '$(Configuration)' != 'CF' " Project="Microsoft.Common.Targets" /> <Import condition=" '$(Configuration)' == 'CF' " Project="Microsoft.CompactFramework.Common.Targets" />
and include any special files and references similarly. I think you'd have to code this up manually at first. I've mostly seen people creating separate project files, but the conditional approach should work.
Again, if I have time tonight, I'll try to create a template (not of the VS variety) for this.
