Bug fixes
- When configuring the Body field of the Send Mail activity using
String.Formatin some projects, the value disappeared after saving and reopening the project. - An
Unable to cast object of type 'Microsoft.VisualBasic.Activities.VisualBasicValue'1[System.Object]' to type 'System.Activities.Argument'validation error occurred when setting the default value of an argument of type String in some StudioX projects. - Auto Arrange did not work as expected in some Windows - Legacy Flowchart projects.
- An expression of type
string.Format("Test {0}", str_text)used in the Body field of the Send SMTP Email activity was incorrectly converted intostring.Format("<P><SPAN>Test </SPAN><SPAN>{0}</SPAN></P>", str_text)when reopening the workflow. - Workflows could not be troubleshot when using a Testing Robot license.
- The cases of a Flow Switch activity were auto arranged when reopening some flowchart workflows.
- The connection of the False branch in a Flow Decision activity disappeared unexpectedly in some flowchart workflows.
- Both design and runtime packages were created after publishing some libraries even if the Separate Runtime Dependencies option was disabled.
- Solving Git conflicts in projects that included Excel files could corrupt those files, preventing them from being opened.
