TypeLite fresh install doesn't work - typelite

Question

I just installed TypeLite into my project via NuGet, but it doesn't work, and everything I've tried hasn't helped... This is the file that was created after installing:
<## template debug="false" hostspecific="True" language="C#" #>
<## assembly name="$(TargetDir)TypeLite.dll" #>
<## assembly name="$(TargetDir)TypeLite.Net4.dll" #>
<## assembly name="$(TargetDir)$(TargetFileName)" #>
<## import namespace="TypeLite" #>
<## import namespace="TypeLite.Net4" #>
<##output extension=".d.ts"#>
<##include file="Manager.ttinclude"#>
<# var manager = Manager.Create(Host, GenerationEnvironment); #>
<# var ts = TypeScript.Definitions()
.WithReference("Enums.ts")
.ForLoadedAssemblies();
#>
<#= ts.Generate(TsGeneratorOutput.Properties) #>
<# manager.StartNewFile("Enums.ts"); #>
<#= ts.Generate(TsGeneratorOutput.Enums) #>
<# manager.EndBlock(); #>
<# manager.Process(true); #>
This is the error I get:

If I choose "Debug T4 template" this is what I get:

If I add this to the file:
<## assembly name="System.Web.Http.dll" #>
Then I get:
Error Compiling transformation: Assembly 'WebUI, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'System.Web.Http, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'System.Web.Http, Version=5.2.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' MyApp S:\MyASpp\Scripts\TypeLite.Net4.tt 1
Unfortunately I haven't been able to figure out where that 5.2.2 reference is; everything in my projects is 5.2.3. If I take the file path to my 5.2.3 DLL and put that in (which is c:\packages... from nuget), it works.
I guess my question is why doesn't it find the DLL reference via the project, or is there a better way to do this? I won't want to have to hard-code paths in this file, ideally I wouldn't need to specify them at all, but I don't know how else to do it at this point.

Answer 1

Got the same error. In my case, all the files that I wanted to be handled by typeLite were in the same assembly so I soved the problem by restricting to the one assembly using the following (in the .tt file):
<# var ts = TypeScript.Definitions()
.For(Assembly.GetAssembly(typeof(MyWebProject.SomeClass)));
#>

Answer 2

T4 templates doesn't know anything about packages installed in your project, so it is necessary to add reference to used assemblies manually.
Obviously T4 is trying to load a wrong version of the library. I would check whether your bin folder contains the correct version of the assembly and I would try to reference the library from there.
<## assembly name="$(TargetDir)System.Web.Http.dll" #>
