Thanks for the quick reply.

Lucky me, I got the installation for the Visual Studio Extension 2.0.0 still in my pc and could downgrade it again. Now everything is working again :)
Thank you so much for your help!!!

Best wishes

I am running into this problem with 2.0.2-final for both the VS extension AND the NuGet packages. It worked for the briefest of moments late last night... then I checked in my work and quit for the day. Did a pull first thing in the morning (nothing had changed) and nothing. All I get is this:

ZbuModelsBuilder: Starting 11/19/2014 12:26:00 PM.
ZbuModelsBuilder: ZbuModelsBuilder failed to generate code: Exception: Response status code does not indicate success (Forbidden)
"API version conflict: client version (0.0.0.0) is not compatible with server version(2.0.2.31)."
ZbuModelsBuilder:    at Zbu.ModelsBuilder.AspNet.ModelsBuilderApi.EnsureSuccess(HttpResponseMessage result)
   at Zbu.ModelsBuilder.AspNet.ModelsBuilderApi.ValidateClientVersion()
   at Zbu.ModelsBuilder.CustomTool.CustomTool.ZbuModelsBuilder.GenerateRaw(String wszInputFilePath, String wszDefaultNamespace, IntPtr[] rgbOutputFileContents, UInt32& pcbOutput, String& errMsg)

Over and over and over again. I uninstalled, re-installed using every method available to me and nothing works. I have even pulled the source down and run the console application against my local site... same problem. The "client version" ALWAYS EQUALS 0.0.0.0.

Damn, I was pretty sure I got rid of those pesky versionning issues!!! Looking at it ;-)

Is there a solution to this? I'm also running in to this problem and i dont have the 2.0 VSIX (if thats even work?)

@Robert - it is possible but it involves a fair bit of jiggerey pokery configuring the Nuget packages/dependencies.  See this thread

Thanks Barry. I did manage to solve this but in the end It just worked when i did reinstall everything (ModelsBuilder, ModelBuilder Site integration and ModelsBuilder VSIX) I think it was that The System.Collections.Immutable was bumped to a higher version, but I'm not at all sure..

Have released 2.0.3 which should take care of most versions issues.

I've got the VSIX extension 2.0.0. Zbu.ModelsBuilder and Zbu.ModelsBuilder.AspNet are 2.0.3-final. When I try to run the models builder I get the following exception:

ZbuModelsBuilder: Starting 27-01-15 10:35:44.
ZbuModelsBuilder: ZbuModelsBuilder failed to generate code: Exception: Response status code does not indicate success (InternalServerError)

Any idea what this could be?

2.0.0 VSIX won't work w/ latest versions - upgrade VSIX. Though you should have got a nicer message.

On the release page of 2.0.3 it says this: "You do not need to upgrade the VSIX extension as it is unchanged since 2.0.0.".

We've still got some websites running on Zbu.ModelsBuilder 2.0.0-final. We don't want to upgrade those. It would be nice it we could have 1 VSIX extension that works on both Zbu.ModelsBuilder 2.0.0-final and Zbu.ModelsBuilder 2.0.3-final.

My bad. 2.0.0 vsix should indeed work with 2.0.3 website - let me check.

OTOH cannot do a vsix that works with 2.0.0 AND 2.0.3+ website because 2.0.0 website does not have the required plumbing to support a "more recent" VSIX. Was added later on which is why 2.0.3 VSIX will talk to 2.0.2 website (because 2.0.2 has the required plumbing to support a "more recent" VSIX -- basically it accepts that the VSIX tells it to please support it).

I understand that you cannot do a vsix that works with 2.0.0 AND 2.0.3+ website, but I've still got the vsix 2.0.0 version which was always compatible with 2.0.0 website and shoud also work with the 2.0.3+ website right? So vsix 2.0.0 should work on both versions.

Jeroen

Exactly, and why vsix 2.0.0 fails is something I cannot explain at the moment - looking into it. I suspect something weird happening with WebAPI - some ppl report what you see (version is null) while others report that version is "0.0.0.0" which does not make much sense either.

So for now it's best to just use vsix 2.0.0 for 2.0.0 website and vsix 2.0.3 for 2.0.3 website. Too bad you can't have multiple versions of the vsix installed. Need to uninstall and reinstall it depending on the website version.
