"GenerateResource" task CLR2 runtime error

Question

My app keeps getting this error (I'm using VS 2013, VB.NET, and Windows 8.1, by the way):

Could not run the "GenerateResource" task because MSBuild could not create or connect to a task host with runtime "CLR2" and architecture "x86". Please ensure that (1) the requested runtime and/or architecture are available on the machine, and (2) that the required executable "C:\Program Files (x86)\MSBuild\12.0\bin\MSBuildTaskHost.exe" exists and can be run.

The app is for .NET 3.5 (3.5 and lower versions get me this error). I try to run the app again. Sometimes, it works; sometimes, the error comes back.

I already tried looking up for answers at Google and the answer they gave me turned out to be: "Your build's username is too long" (they said that 20 characters or more cause the error), but it's not true. My user name is 5 characters only. Anyway, I don't think my build's username's length has anything to do with it; it makes no sense.

Does anyone know what is wrong with 3.5 and lower versions? Thank you.

Answer 1

This fixed the issue on my machine:

To resolve it, go to your csproj file and add the following line under the default property group:

<PropertyGroup>
    ...
    <DisableOutOfProcTaskHost>true</DisableOutOfProcTaskHost>
</PropertyGroup>

Clean and rebuild solution worked for me.

Adding this in each project is a cumbersome task. So you can set it in the environment variables.

Click Start>> Right-click Computer >> Properties >> Advanced system settings >> Click Environment Variables button to open the dialog, then under the System variables section, click New… button, type the Variable name = DISABLEOUTOFPROCTASKHOST, and type the Variable value = 1, then click Ok.
