I am currently running SQL Server 2014 and trying to execute a stored procedure that sends out an email using sp_db_sendmail which is failing with the following error.
An error occurred in the Microsoft .NET Framework while trying to load
assembly id 65549. The server may be running out of resources, or the
assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or
UNSAFE. Run the query again, or check documentation to see how to
solve the assembly trust issues. For more information about this
error: System.IO.FileLoadException: Could not load file or assembly
'sqlwebrequest, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'
or one of its dependencies. An error relating to security occurred.
(Exception from HRESULT: 0x8013150A) System.IO.FileLoadException:

Originally the sp_db_sendmail was working but since moving the database that calls the code to a new server I am getting the above message.
I have made the owner of the database the same as it was on the original server "sa" and also set the database to be "Trustworthy" which seems according to relevant googling should fix the problem, but still no luck.
Any further suggestion would be appreciated.

Here's line 15 of Context.vb:
Database.SetInitializer(New MigrateDatabaseToLatestVersion(Of Context, Migrations.Configuration))
A pretty straightforward database call, I'd say.
However, when I bumped back down to EF6.2, the error stopped.
I'm finding plenty of references to the individual exceptions here on SO, but nothing I've found so far quite fits the context of the combination of the three taken together with what the code is doing (general database access).
Do I need to alter my DAL code somehow in order to accommodate the EF6.4 update? Were there some breaking changes?

This occurs under both EF6.2 and EF6.4.
If this is occurring on your remote deployment and not your local development environment after upgrading the EF version then I would suspect there is an issue with the deployment process.
Check the web.config in the deployed build to ensure that there are no EF-related runtime version dependency version overrides. (EntityFramework.dll and EntityFramework.SqlServer.dll)
Check the EntityFramework.dll assembly version between the deployed file on the remote server and your working local instance.
Copy the deployment from the remote server into a local folder, point IIS at it and then hook VS up running your project using Attach to Process on w3wp.exe. Set a breakpoint somewhere in the code and check that it remains a "hot" hit-able breakpoint and not an inactive one stating something along the lines of "The breakpoint will not currently be hit. The source line does not match..." This would indicate that the deployed code does not reflect a current, complete rebuild of what you are running in VS.
If you are using an automated build:
Check that dependency DLLs are not being checked in and that the build machine is actively resolving NuGet packages properly.
Check your references for EF, both before you upgrade the EF version (Source control revert all changes, use what was last built and deployed) Under the project explorer under References, select EntityFramework and check the path listed. It should be pointing to:
{Your solution folder}\packages\EntityFramework.6.2.0\lib\net45\EntityFramework.dll
If it is pointing to anything like a \bin\debug etc. folder, remove the reference and repair to point at the NuGet package.
If NuGet packages folder is checked in, make sure this folder is complete and up to date in source control. When checking in nuget folders (as opposed to package version locking) I find this needs to be done from Explorer / TFS as normal VS checkins won't include them in pending changes. (unlike /bin folder changes if you accommodate them.) package folder updates can be skipped when initial checkins were made but then things like .ignore files are added/updated causing newer .dll files not to be updated.
Check for any stale or mismatched project files (.csproj/.vbproj) in your local environment vs. what is in source control. Often these can get flagged at some point as "Excluded Files" resulting in the automated build using out of date references.
Have a check through these and see if that identifies anything.
I'm using EntityFramework version 6.1.3.
I copied migrate.exe from EntityFramework version 6.1.3 package tool folder to bin folder of my website.
My web site is compiled and published to production environment with x86 CPU and target framework 4.5.1
I run the following command:
D:\Sites\MatrixPortal\bin>migrate.exe
d:\sites\MatrixPortal\bin\MatrixPortal.BL.dll
/startUpDirectory="d:\Sites\MatrixPortal\bin"
/startUpConfigurationFile="d:\Sites\MatrixPortal\Web.config"
and i get the following error:

(Exception from HRESULT: 0x80131047)

when i try this:
migrate MatrixPortal.BL.dll /verbose
i get other error:

also tried this:
http://www.azurefromthetrenches.com/command-line-entity-framework-code-first-migrations/
and created a file called Redirect.config with the following content:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<bindingRedirect oldVersion="0.0.0-6.1.3" newVersion="6.1.3" />

</assemblyBinding>
</runtime>
</configuration>
but got the same error as above :(
In my case I got the error because I wrote migrate .\MyAssembly.dll instead of migrate MyAssembly.dll.
See Common Problems documentation section.
SOLVED!
I've Published the web site project with x86 target cpu, and apparently it wasn't really x86, i don't know why, maybe a bug?
After changing Publish to any cpu it worked. i was able to run migrate.exe without an error using the following arguments:
migrate.exe MatrixPortal.BL.dll /verbose /startUpDataDirectory="D:\Sites\MatrixPortal" /startUpConfigurationFile="D:\Sites\MatrixPortal\Web.config"

Nevertheless I got a similar scenario running with power point and had to do the following steps to get rid of the error you describe:
Run Microsoft Management Console (mmc.exe)
Add Snap-In for "Component Services"
Search for Computers\My Computer\DCOM Config\Microsoft Office Power Point Slide\ (you may search for something that sounds correct for your word-scenario)
Open Properties > Tab "Security"
"Launch and Activation Permissions" > Edit ...
Add your application pool user to this list and allow "Local Launch" and "Local Activation"
I am working on a MVC 2 application. I deployed an MVC 2 application to IIS 7 and it doesn't work. This is the first time deploying MVC application. I believe I configured it well, but get blank page.

I have an application that is being hosted in medium trust environment (godaddy). I am getting strange problem that occurs periodically when I am trying to use the application.
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I have read a bunch of other posts that talk about issues running in a medium trust environment. My question really goes to trying to understand why it works sometimes and other times I get the above message. When error occurs it will eventually correct itself. And obvously if I recycle IIS that fixes is as well. I'm hoping their is a workaround for this.
Based on the callstack it looks like it related to esablishing the connection and trying to load the MetadataWorkspace from my assembly. My MetadataWorkspace is contained in my App_Code folder for my web app.
