What should .net framework version be for an addin targeting only Visual Studio 2010?

Question

The projects in an Addin solution, targeting only Visual Studio 2010 can have .net framework 3.5 or 4.0?

Does this cause a problem?

PS: And are there any restrictions for TFS integrated addin versions?

Thank you in advance.

Answer 1

You target 4.0:

Per the plugin migration document from Microsoft:

Update the following project properties. (In the Solution Explorer, under the project node, click Properties.) in the Application tab, change TargetFramework to the .NET Framework 4

You may find significant value in the Visual Studio Integration SDK documentation. Best of luck.
