Have you tried to adapt the proof to the pointwise situation?

comment weakly open subset in $M[0,1]$ (the space of finite measures on $[0,1]$)
What are the continuity points of a measure $f \in G \subset M[0,1]$?

comment Linear programming in Hilbert spaces
There seems to be a typo in question 1, should it be "...implies $C$ is closed in ..."?

comment Estimates of $L^2$-orthogonal projection in $H^1$ and $H^{-1}$-norm
If $M_k \subset L^2(\Omega)$, $Q_k w \not\in H^1(\Omega)$, hence $\|Q_k w\|_1$ is not defined. And similar, $Q_k w$ is not defined for $w \in H^{-1}(\Omega)$.

You did not substitute the integration boundaries.

comment Is the complex Banach space $C([0,1])$ dual to any Banach Space?
Can the function $f$ with $f(t) = 1-2\,t$ for $t<1/2$ and $f(t) = 2\,t\,\mathrm{i}$ for $t \ge 1/2$ be written as a convex combination of two extreme points?

comment a question about prove an exponential matrix function can be infinitely differentiable
Calculus for matrix functions can be found in, e.g., Bhatia's Matrix Analysis, Theorem V.3.3.

comment Adjoint operator on Banach space
The most trivial counterexample would be the zero operator $T = 0$ from $X = \{0\}$ into an arbitrary Banach space $Y$.

I have expanded my answer. Note that your sequence only converges in the weak-* topology, but not in the weak or the norm topology.
