To ensure the LocalNative provider assembly you built works, you should run the assembly with the Maestro API test runner Copy the LocalNative provider assembly and its supportng dlls to the Test directory of the SDK Edit the ConnectionProviders.xml file to include an entry for your LocalNative provider assembly. The name of the provider must be Maestro.LocalNative and the type must be OSGeo.MapGuide.MaestroAPI.LocalNativeConnection If you built the LocalNative provider against the 32-bit MapGuide .net assemblies, run MaestroAPITestRunner.exe to run the test suite If you built the LocalNative provider against the 64-bit MapGuide .net assemblies, run MaestroAPITestRunner64.exe to run the test suite If the test runner reports 0 test failures, your LocalNative provider has passed validation.
