This exception was originally thrown at this call stack:

Inner Exception 1:
COMException: Unable to load report.
Here is my code to load the rpt file to the viewer
ReportDocument rpt = new ReportDocument();
rpt.Load(#"D:\sample.rpt");
reportviewer.ReportSource = rpt;
reportviewer.Refresh()
So far, I have tried;
Double checking my destination where the .rpt file is
Deleting everything in the TEMP folder
Setting my printjob to -1
And reinstalling both 32 and 64 bit runtime
Any ideas how to fix this? Any help are appriciated!

I have installed the connector below one
https://dev.mysql.com/downloads/connector/net/
but not working
I am using the 5.0 framework
this is the screenshot of the error in visual

Have you tried with the following installation?
PM> Install-Package MySqlConnector -Version 1.3.1
This could be a workaround!

.NET WinForms: Cound not load System.Runtime

I was writing an app for a friend who wanted an easy way to use Morse Code.
I was attempting to use an External Library that I wrote with Morse Code support, and when I try to call it, I get this error, in an External "Control.cs" file. I found happened in both Visual Studio and JB Rider, though Visual Studio gives a different error as it can't debug external sources.
My usings are:
using CainsSharpTools; // <= This is my Library
using System.Diagnostics;
using System.Windows.Forms;
And my function call looks like this:
private void buttonEncode_Click(object sender, System.EventArgs e)
=> textBoxMorse.Text = MorseCode.Parse(textBoxPlain.Text).Value;
The error is
System.IO.FileLoadException: Could not load file or assembly 'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

FWTools/GDAL error in release version

I'm using FWTools and SharpMap (with gdal_sharp) to build an application. And I have a weird error. Loading a raster layer runs great in Debug mode, but in Release it throws an Exception in SharpMap.Layers.GdalRasterLayer in the constructor when calling
_projectionWkt = _gdalDataset.GetProjectionRef();
The full exception is:

The weird thing is that in Debug everything works fine. The build setup is exact, both .Net 4.0, x86 Platform.
Any ideas?
Thankyou in advance

I ran into similar problems but after using the current compiled binaries from Link the problem was fixed. I documented the steps that worked for me at http://vipassanaandenvironmentalinformatics.blogspot.co.nz/2013/03/getting-started-with-c-and-gdal.html.
Hope this answer is still of help to others.

It seems to be a problem with Windows 8 and it's DEP implementation along with .Net 4.0. I'm using a C++ dll in a wrapper, and the OS does not let it execute. It could be solved by editing the DLL or turning Data Execution Prevention off.

pls any one help me on this .....pls i am stuck in this for whole day

To check the machine's installed wmp codecs:
Go to WMP, press alt to get the menu, select Help->About... then click Tech Support Info. It will generate a report which amongst other things lists all the supported audio and video codecs.
Do this on both machines, Hopefully this should reveal the missing codec.
