Null check indicator ideas for NT8

One day I just had the sh*ts with NT8 having brush freezing/disposal issues when left idle for a while ie. possible multi-threading issues.
I decided to write some extension methods that might help with this. (Warning: these are not thoroughly tested!)

eg.

 

Code

// normal code for freezing a brush Brush myBrush = Brushes.Red; myBrush.Freeze();

I've written an extension that checks it for null before freezing it:

 

Code

// extension code instead Brush myBrush = Brushes.Red; myBrush.NotNullFreeze();

Also disposal of SharpDx objects:

 

Code

SharpDx.Direct2D.Brush myBrushDx; // Dispose by if(myBrushDx != null)       myBrushDx.Dispose(); //Extension instead myBrushDx.NotNullDispose();

I've also created an opacity extension:

 

Code

Brush myBrush = Brushes.Red; myBrush = myBrush.ChangeOpacity(int Opacity); // or double Opacity myBrush.NotNullFreeze();

You can also use the 'NotNull' extension to check for null values within Linq statements. Please peruse the actual indicator for some ideas. You will find the extensions within the Addons folder called Sim22BrushExtensions and Sim22NotNullExtensions. The actual indicator does nothing, it's just for the code: Sim22_NullSample.

You need to make sure in the declarations you set: using Sim22BrushExtensions; using Sim22NotNullExtensions;

I'd appreciate anyone having a play and suggesting ideas. I won't be able to answer for a few days so I hope I wake to find some interesting comments
