We're building a C# wrapper for a C library in embedded Linux, and we want to install it into the GAC of the target system.
To do that, I've used sn to create a keypair and mcs to compile the code:
sn -k keypair.snk
mcs /target:library -keyfile:keypair.snk -out:MyLib.dll src/*.cs
Now, once that's built, I use gacutil to inject it into the GAC with:
gacutil /i -gacdir /path/to/gac MyLib.dll
What I end up with is the correct file structure but the version number is set to 0.0.0.0:
.../usr/lib/mono/gac/MyLib
.../usr/lib/mono/gac/MyLib/0.0.0.0__3141592653589fff
.../usr/lib/mono/gac/MyLib/0.0.0.0__3141592653589fff/MyLib.dll
I want the version of the wrapper to match that of the underlying C code being used so my question is (hopefully) a simple one. Where is that current version coming from, and how do I get it to be 3.14.15.9 (for example)?
Add an assembly level attribute called AssemblyVersion to your C# source. This is usually added in a file named AssemblyInfo.cs :
Note: This is a cut/paste of an auto-generated project file, I updated the AssemblyVersion attribute and you only have to include the attributes you want the CIL assembly to contain
using System.Reflection;
//using System.Runtime.CompilerServices;
// Information about this assembly is defined by the following attributes.
// Change them to the values specific to your project.
[assembly: AssemblyTitle("Sushi.Task.Lib")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("SushiHangover")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("SushiHangover - 2016")]
[assembly: AssemblyTrademark("SushiHangover")]
[assembly: AssemblyCulture("")]
// The assembly version has the format "{Major}.{Minor}.{Build}.{Revision}".
// The form "{Major}.{Minor}.*" will automatically update the build and revision,
// and "{Major}.{Minor}.{Build}.*" will update just the revision.
[assembly: AssemblyVersion("3.14.15.9")]
// The following attributes are used to specify the signing key for the assembly,
// if desired. See the Mono documentation for more information about signing.
//[assembly: AssemblyDelaySign(false)]
//[assembly: AssemblyKeyFile("")]
Add that source file to the others that you are compiling.
Install it:
>gacutil /i Sushi.Task.Lib.dll
And retrieve the details:
>gacutil /l |grep -i sushi
