Differences between Microsoft .NET 4.0 full Framework and Client Profile
The Microsoft .NET Framework 4.0 full installer (32- and 64-bit) is 48.1 MB and the Client Profile installer is 41.0 MB. The extracted installation files are 237 MB and 194 MB respectively, and once installed, they are 537 MB and 427 MB.
This is a difference of 110 MB. What difference is there between the two packages?
When is it preferable to install the Client Profile instead of the full .NET Framework?
What's new in .NET Framework 4 Client Profile RTM explains many of the differences:
When to use NET4 Client Profile and when to use NET4 Full Framework?
NET4 Client Profile:
Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).
NET4 Full framework:
Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes:
o ASP.Net apps
o Server-side ASMX based web services
o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.
o Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)
However, as stated on MSDN, this is not relevant for >=4.5:
Starting with the .NET Framework 4.5, the Client Profile has been discontinued and only the full redistributable package is available. Optimizations provided by the .NET Framework 4.5, such as smaller download size and faster deployment, have eliminated the need for a separate deployment package. The single redistributable streamlines the installation process and simplifies your app's deployment options.
You should deploy "Client Profile" instead of "Full Framework" inside a corporation mostly in one case only: you want explicitly deny some .NET features are running on the client computers. The only real case is denying of ASP.NET on the client machines of the corporation, for example, because of security reasons or the existing corporate policy.
Saving of less than 8 MB on client computer can not be a serious reason of "Client Profile" deployment in a corporation. The risk of the necessity of the deployment of the "Full Framework" later in the corporation is higher than costs of 8 MB per client.
A list of assemblies is available at Assemblies in the .NET Framework Client Profile on MSDN (the list is too long to include here).
If you're more interested in features, .NET Framework Client Profile on MSDN lists the following as being included:
And the following as not being included:
