Hello, how are you?
I'm trying to find a solution for this problem and I'd like to know if some of you have seen something like this.
I develop a web application which use MapGuideAPI (MapGuideApiDotNet) and it was running well on .NET Framework 2.0. However, that application was updated to .NET Framework 4.0 and when the web page tries to initialize MapGuideAPI, using the method MapGuideApi.MgInitializeWebTier(webconfig.ini), I receive an MgUnclassifiedException.
I tried to update my MapGuide to 2011 version (actually I'm running 2010 version) but the error persists.
But the most uncommon behavior is that after trying to run the application some times, the error doesn't occur.
I'm running Windows XP SP3, IIS 5, MapGuide2010 and Visual Studio 2010 w/ .NET 4.0. I've made some tests in a server running Windows 2003 R2 and IIS 6 but the same error appears.
Any comments or solutions, please let me know.
Check out the useLegacyV2RuntimeActivationPolicy setting in your web.config file (google for it. It's a common issue with loading CLR 2.0 assemblies into a CLR 4.0 process)
Hi Jackie, how are you?
Thanks for the tip. I checked at MSDN Library how to use this parameter and set it in my web.config file but unfortunately it didn't work.
I'm still looking for a solution to this issue and I'll publish it if I find it.
I am also experiencing this issue. It has been intermittent and we are at a loss as of now. Any help would be greatly appreciated.
MapGuide has not been migrated to asp.net 4.0 yet. So please make sure your app pool is using asp.net 2.0.
Yes, the AppPool running this is 2.0, as you can see by the .NET version line at the bottom of the image I attached.
We do have .NET 4.0 installed on this server running in a different AppPool. Are there any known issues with that configuration?
Have you ever checked the version of MapGuide assemblies your are referecing? You should alsways copy all *.dll from <MapGuide WebExtension>\www\MapViewerNet\bin to <yourApp>\Bin folder.
And make sure your are using the same file webconfig.ini as the one in <MapGuide WebExtension>\www\ when initialize webtier.
You may get some unexpected problems if you are using different versions.
