Problem building BizTalk solutions with standalone MSBUILD

We are in the process of setting up a build server for BizTalk 2010 for one of our customers. Naturally we wanted an installation that was as clean as possible and we were very pleased to find out that we only need the “Project Build Component” from the BizTalk installation and not a full-blown BizTalk or even Visual Studio to build the BizTalk project. The description of the project build component clearly states that “Project Build Component enables building BizTalk solutions without Visual Studio” and MSDN confirms that no other component should be needed http://msdn.microsoft.com/en-us/library/dd334499.aspx.

We installed the .NET SDK and the project build component and started testing.

We started off by building some shared schema solutions and it worked just fine but when we tried building a project with some more BizTalk artifacts, schemas, mappings and pipelines, boom!

The “MapperCompiler” task failed unexpectedly. System.IO.FileNotFoundException: Could not load file or assembly ‘Microsoft.VisualStudio.OLE.Interop, Version=7.1.40304.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The system cannot find the file specified. File name: ‘Microsoft.VisualStudio.OLE.Interop, Version=7.1.40304.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.

That is a bit odd since “Project Build Component enables building BizTalk solutions without Visual Studio” and yet it complains about a missing Visual Studio assembly?

Unwillingly to give up and install Visual Studio we started investigating what would break the build. If we removed the mappings and just build the schemas and pipelines, it worked. If we added one of the xml-schema-to-xml-schema mappings, it worked. If we added one of the flat-file-schema-to-xml-schema mapping, boom! I am not sure why a flat file schema is different from an xml schema from the mappings perspective but apparently it is.

Eventually we decided to install Visual Studio and BizTalk Developer Tools on the build server and now we are able to build this project as well.

This is not that big of an issue for us since we didn’t have to install and configure a full-blown BizTalk with a SQL Server but the MSDN article is misleading and it took us a while to give up and install Visual Studio.
