Edited Unassigned: Can't find MapControl in Visual Studio 2012 [24217]
I create a Winform project in Visual Stduio 2012 with .Net framework 4. Then install DotSpatial.Control and its dependency by NuGet.
Every thing is OK. But when I choose DotSpatial.Control to add toolbox items, I found there's no MapControl!
Can you tell me how to resolve? Thanks!

Closed Issue: Removing raster layers does not lead to consequent release of memory resources [23970]
I found a bug in loading raster files with dotspatial libraries (either with or without the use of Gdal libraries).
When loading a raster file the memory usage (executable size in memory) increases by almost 3 times the size of the input file.
Removing the newly loaded raster layer does not lead to a consequent memory release.
If I call myself GC.collect() some of the memory is released but not all of the memory increment due to the raster loading.
Loading again the same raster after removing it leads to a further increment of memory usage higher than after the first loading.
So the consequence is that this bug leads to a quick memory saturation if one is working with a number of raster layers.
I debugged my application when calling the "map1.addlayer()" but could not find where the bug is (the library code is too nested for my programming skills).
I think this is a strong bug for those working with raster data.
Comments: I did testing with this patch and memory releasing working perfectly. I'm closing this issue.

Commented Issue: File is not closed after Raster.Save() [23885]
Trying to open a tif raster file after calling Save method results in IOExcetpion "File is being used by another process"
Sample code:
```
AppManager app = new AppManager();
app.LoadExtensions();
IRaster raster = Raster.CreateRaster("test.tif", null, 20, 20, 1, Type.GetType("System.Single"), new string[1] { "" });
raster.Save();
File.Open("test.tif", FileMode.Open, FileAccess.Read, FileShare.None);
```
Even if I try calling Close and Dispose the error persists.
Creating a raster with same name results in error too:
```
AppManager app = new AppManager();
app.LoadExtensions();
IRaster raster = Raster.CreateRaster("test.tif", null, 20, 20, 1, Type.GetType("System.Single"), new string[1] { "" });
raster.Save();
raster.Close();
raster.Dispose();
IRaster raster2 = Raster.CreateRaster("test.tif", null, 20, 20, 1, Type.GetType("System.Single"), new string[1] { "" });
```

Not reproduced with latest DS.
This code working fine.

raster.Save();
raster.Close();

// .... do something with file

Commented Issue: Saved Int32 value in DBF is read as Int64 [24177]
If have created a test to write Int32 values with the FeatureSet to the DBF. When reading the data back a cast exception is thrown, because the FeatureSet reader has determined that the value is of type Int64. It should be Int32..

Commented Issue: Poor performance using AddShape [23740]
I need to create point layer with many points. The performance is poor. Tracing into DS source, the slowdown occurs in DotSpatial.Data.FeatureSet Vertex property. Each time a shape is added, all prior shapes are iterated through and their vertices are reset. So as the shape file grows, the performance gets slower and slower.
I don't understand the code well enough to know if this is be design (to perhaps reset some indices) but it results in unacceptable performance.

New Post: DotSpatial "TrackingLayer"?
The point drawing code I supplied was just for informational purposes. You will need to come up with your own data to draw. The arrowInfo was very application specific to drawing direction arrows.
To draw polygons, you should do something like this:
_dsDrawUtil.Symbolizer = DSDrawingUtil.CreatePolygonSymbolizer(....);
_dsDrawUtil.DrawPolygon(...);
You should be able to pass null for the shClip argument to DrawPolygon if you do not need to clip. I vaguely recall that I had to add clipping when I had data that extended WAY outside the normal window extent. I think it was something to do with GDI+ not liking window coordinates greater than a 16-bit number or something along those lines.

Commented Issue: ProjectionInfo.Over not used in Reproject.ConvertToLatLon [23809]
Reproject is not taking source.Over into account before it calls Adjlon near the end of ConvertToLatLon. I suggest to wrap the line with
if (!source.Over)

xy[i * 2] = Adjlon(xy[i * 2]);

DotSpatial assumes that ShapeFiles with PointZ have four values (x, y, z and m). Our ShapeFiles that are PointZ only have three values (x, y and z).
