Question

I am experiencing a strange issue with VS2010. We use TFS to build our API dlls and we used to reference them in our projects usign a mapped network drive that was fully tru

Answer 1

For those of you running a 64bit version of the TFS build service, I had to create the config file in the following path:

 C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\x64

And the file contents:

<?xml version ="1.0"?>
<configuration>
<runtime>
    <loadFromRemoteSources enabled="true" />
</runtime>
</configuration>

Answer 2

I had the same error and found my DLL was "blocked". Open up the DLL in explorer, right click -> properties -> press 'Unblock'.

Answer 3

In my case bunch of dlls were blocked.

To unblock all files in folder I used power shell with following command

dir -Path [directory path] -Recurse | Unblock-File

Answer 4

Adding the snippet below to the app.config file worked in my case. I'm Running Windows XP, with VS2010 service pack 1.

<configuration>
  <runtime>
    <loadFromRemoteSources enabled="true" />
  </runtime>
</configuration>

Answer 5

I got a similar problem and I finally got over with it by removing the licenses.licx file in the Properties folder of the solution.

Answer 6

Had the same problem and the config change didnt work. Only when i set Generate Serialization Assembly to off in the project properties did it work.
