After all, what exactly would Target framework?
Is the version of framework .NET for the entire project. Newer versions have more features, more features, and language specification, such as C#, becomes more advanced.
What is your function?
The framework is the toolkit implemented by Microsoft. Basically, all the non-primitive classes are part of it.
Changing it may cause problems in the application or server?
It depends. Changing to an old version can cause problems. Change to a new version, hardly, except for rare exceptions, but whose exceptions are properly documented on the Internet.
What are the disadvantages of being outdated?
Several, I would say. New features come out with some constancy. Asynchronous programming, for example, does not exist natively in version 4 of .NET. It needs to be added as an extra package. Newer versions tend to be better at performance and data security.
What is the relationship between the Entity Framework and the Target framework? What is the dependency between them?
The Entity Framework is dependent on the. NET version you are using. Version 6, for example, depends on the framework 4.5 for operation.
Updating one can affect the other?
Can.
Upgrading . NET to a newer version does not affect the Entity Framework. For an older version, it may affect.
Updating the Entity Framework may, in some cases, create an incompatibility with the . NET, but this only happens if the . NET version is too old.
Can I use a newer version of EF in an application with the old Framework?
Also depends. Version 6 still supports . NET 4.0. See this link for more information.
