Problem Unit Testing T4 Templates in VS2008

Hi,

I am using unit tests to test my templates, using the Engine and the TemplateHost class.

string rootDir = Directory.GetCurrentDirectory();
IDictionary<string, PropertyData> arguments =
new Dictionary<string, PropertyData>();

arguments["myarg"] = new PropertyData(1, typeof(long));
TemplateHost host = new TemplateHost(rootDir, arguments);

host.TemplateFile = "myfile.t4";

Engine engine = new Engine();
engine.ProcessTemplate(File.ReadAllText(host.TemplateFile), host);

The instruction engine.ProcessTemplate just stop the test with the error

Test method mymethod threw exception: System.EntryPointNotFoundException: Entry point was not found..

Microsoft.VisualStudio.TextTemplating.ITextTemplatingEngineHost.get_TemplateFile()
Microsoft.VisualStudio.TextTemplating.Engine.ProcessTemplate(String content, ITextTemplatingEngineHost host)
mymethod() in myfile.cs: line 78

I am using VS2008, GAX Feb 2008 and GAT for VS2008.

Any idea?

Thanks in advance

Hi,

Actually GAX is still using a text template 8.1 assembly version, so what you can do is fix your reference (which actually should be 9.0) and use the 8.1 version or you can also add the following assemblies redirects in your devenv.exe.config:

<dependentAssembly>
<assemblyIdentity name="Microsoft.VisualStudio.TextTemplating" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Microsoft.VisualStudio.TextTemplating.VSHost" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
</dependentAssembly>

hth.
