TitleCannot add a new assembly to Developer Studio for OpenEdge
URL Name000036394
Article Number000159724
EnvironmentProduct: OpenEdge
Version: 11.x
OS: Windows
Other: Progress Developer Studio for OpenEdge
Question/Problem Description
Attempting to use a third-party .NET assembly in Developer Studio but cannot to add it to Referenced Assemblies.

Attempting to use a third-party STPadLibNet.dll .NET assembly in Developer Studio but cannot to add it to Referenced Assemblies.

One of the following errors occurs:
Add Assembly References
The following library could not be loaded:
Assembly Load Failure
The following assemblies failed to load and will not be added to assemblies.xml:
STPadLibNet, Version=, 

Since the control has both visual and non-visual classes, it is possible to add the control to the toolbox and then to a form.
The form can be run and a property of the control displayed without errors. However, when the Project  is restarted, the assembly cannot be loaded again; forms is not visualized, etc.
Using PROASMREF.exe to add the assembly directly to assemblies.xml initially succeeds. However, the failure occurs when Developer Studio is loaded; the assembly then shows an error.

Per documentation for the control, creating PROASMREF.EXE.CONFIG with the appropriate entries has no effect.

PROWIN32.EXE.CONFIG already contains the useLegacyV2RuntimeActivationPolicy setting. 
Using the same assembly in OpenEdge Architect 10.2B works as expected.

Steps to Reproduce
Clarifying Information
According to the documentation for the control:
.NET 4.0
The .NET 2.0 runtime activation policy must be enabled in order to use the STPadLibNet.dll components in .NET 4.0 based projects. The 'app.config' file must be edited within the project as follows for this purpose:
<?xml version="1.0"?> 
 <startup useLegacyV2RuntimeActivationPolicy="true"> 
  <supportedRuntime version="v4.0"/> 
Error Message
Defect/Enhancement NumberDefect PSC00246846 / OE00223889
Eclipse JVM process (javaw.exe) also requires a .config file containing additional configuration information. 
Manually add the missing configuration details, using the following steps:

1) Create new .config files: 

For OpenEdge 11.0, 11.1, 11.2:
<Install location>\DeveloperStudio3.X\jre\bin\javaw.exe.config 

For OpenEdge 11.3+,

2) Add the following entry to each .config file: 
<loadFromRemoteSources enabled="true" /> 
<startup useLegacyV2RuntimeActivationPolicy="true"> 
<supportedRuntime version="v4.0"/> 
3) Open <DLC>\bin\prowin32.exe.config in Notepad. Change this entry: 
<loadFromRemoteSources enabled="false" /> 
To "true", e.g.: 
<loadFromRemoteSources enabled="true" /> 
4) Restart Developer Studio for OpenEdge.

It should now be possible to add and use the STPadLibNet assembly as expected.
