//The only problem is that SecurityProtocolType in .NET 4.0 doesn’t have an entry for TLS1.2,

add the type parameter to the method instead of the class, and use a different function name

// Type parameter on the method - the compiler infers the type:
StopWatch.MeasureFunction(() => 42);
StopWatch.MeasureFunctionDisposable(CreateSomeDisposableThing);

// Type parameter on the class - you must specify the type:
StopWatch<int>.MeasureFunction(() => 42);

// Type parameter on the class and the method - you must specify the type for the class, but it's not used by the method:
StopWatch<object>.MeasureFunctionDisposable(CreateSomeDisposableThing);
