How can I deploy .NET v4.0 application on target environment without .NET v4.0?

Question

How can I deploy .NET v4.0 application to some target servers where installing .NET v4.0 is not an option? Recompiling to v3.5 is not feasible too because I have been using Task Parallel Library. Should I use NGen.exe? Does anyone have the experience?

Answer 1

You can't. If there is a dependency on .net 4 then the framework must be installed as well.

Your only options are:

1. Convincing the server owners to install .net 4
2. Remove usage of any 4.0 framework dependencies and retargetting your application.
3. Deploying to different servers that do have .net 4 installed.

Answer 2

You cannot. An application compiled for framework 4.0 will require framework 4.0 to run. Alternatively you can expose the functionality written for framework 4.0 through webservices and consume them through a 3.5 client.

You do not. Point. They also can not run Linux or MAc software.

Does anyone have the experience?

Yes. I dont deploy it. If it is a customer - no way. If it was my job to make the software for them to run, I get fired, as I should for not asking first.
