Maestro: Cannot build custom LocalNativeProvider

[gBecker]

Hi Jackie,

I'm trying to build a custom LocalNativeProvider for the latest MapGuideOpenSource Version (3.0) using the LocalNativeProvider-Tool from Maestro (build from trunk). As you can guess: it doesn't work! The custom LocalNativeProvider isn't build!

First, the tool tries to sign the dll's located in the "MapGuide .net assemblies directory" wich works, except for the none existing MapGuideDotNetApi.dll. I do not think that this is the reason for not building the custom provider, cause this file doesn't already exists in former versions of MGOS.

I think the root cause is the the tool can't find a specific dll named "NetTopologySuite.Merged.dll". You can see it in the log:

Thanks, Gunter

Ah, in my process of NuGet-ifying as much of Maestro's external libraries, I forgot to update the LocalNativeProvider build tool to use the new expected assembly set.

[jng]

OK this is a bit more complicated

because Maestro now targets C #6, the provider template tool cannot just shell out to CSC.exe to compile the provider assembly. We have to programmatically do this with the Roslyn APIs

[jng]

Ok, you should be able to build the local native provider against MGOS 3.0 now on trunk.

Unfortunately there is an error when trying the new build of the LocalNativeProvider:

Could not load file or assembly 'OSGeo.MapGuide.MaestroAPI.Native-3.0.0' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I think the LocalNativeProvider dll is missing the PublicKeyToken of the MaestroAPI as you can see in this report from .NET Reflector:

Assembly OSGeo.MapGuide.MaestroAPI.Native-3.0.0.dll, Version 0.0.0.0 Location: C:\Users\CSO\Documents\Visual Studio 2015\Projects\MapGuide3\MapGuide3\bin\OSGeo.MapGuide.MaestroAPI.Native-3.0.0.dll Name: OSGeo.MapGuide.MaestroAPI.Native-3.0.0.dll, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null Type: Library

Patch for ProviderTemplate

[gBecker]

I got it!

It wasn't the missing PublicKeyToken (maestroapi.key), but a wrong AssemblyName in ProviderTemplate. I fixed it in Code and created a patch.

[jng]

Fixed. Thanks for the patch.
