I need a working example of a Dockerfile for creating a .NET build server image.
No matter what I install, I get the following error, when try to build my projects with the container:
error MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.5.2" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.
My current Dockerfile looks like this:

What is missing here?

In order to transfer a Docker image from one server to another, what you need to do is first export the image to a file, then copy that file over from your current server to the new one using scp or rsync and finally load the image to your new server.
The Microsoft container ecosystem Run Windows-based or Linux-based containers on Windows 10 for development and testing using Docker Desktop, which makes use of containers functionality built-in to Windows. You can also run containers natively on Windows Server.
The docker build command builds Docker images from a Dockerfile and a “context”. A build's context is the set of files located in the specified PATH or URL . The build process can refer to any of the files in the context. For example, your build can use a COPY instruction to reference a file in the context.
Your dockerfile installs the 4.6 Targeting pack but no targeting pack for 4.5.2.
The files need to be in
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2
for MSBuild to resolve them correctly
