error when using RenderToFile

Oct 21, 2009 at 4:52 PM

I am getting this error after upgrading to Visual Studio 2010

Error 17 Running transformation: System.TypeLoadException: Could not load type 'Microsoft.VisualStudio.TextTemplating.ITextTemplatingEngineHost' from assembly 'Microsoft.VisualStudio.TextTemplating.10.0, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Any idea as to why?

To expand on the above - if I create a script template and run it with no modification I get the above error also.  I am using VS2010 Professional Beta 2.

Same problem here.

@Rob: Have you found a solution already?

Tried looking in 'Microsoft.VisualStudio.TextTemplating.10.0.dll' and that interface is not implemented although the documentation indicates it should be?


To overcome, have changed my T4 code to not use rendertofile so all it now created to a single file rather than to multiple files which meant I no longer need to use T4Toolbox so can remove the include. 


Let me know if you want to know any more details.

If you are using Beta 2, please install build of the toolbox.

Oleg, Rob,

Thanks for your quick responses. Will check changes later today.

Kind Regards,
