Symptoms
When trying to enter play mode, I am receiving the error below:
error CS0131: The left-hand side of an assignment must be a variable, a
property or an indexer
Cause
The CS0131 error is caused when the = assignment operator does not have a variable, property or indexer to the left hand side of it.
Here is how the error appears in this example:
error CS0131: The left-hand side of an assignment must be a variable, a
property or an indexer
Resolution
The error CS0131 is resolved by adding a variable, property or indexer to the left hand side of the = assignment operator.
